it does not cause front end wandering. What is Seat Tube Angle? Running 64 on 150 29er. The same head angle for trail and enduro????? Other things being equal, a bike with a steeper head angle with steer more sharply and a bike with a slacker head angle will be more inclined to travel in a straight line. So if theres one key takeaway point, its that you shouldnt be afraid to experiment with settings, adjusters and riding position. But just like the seated posture example given above, thats going to be a difficult change to instil, especially if youve been riding for any length of time. 68 seems to be a fairly normal head angle for a hardtail, and assuming the same 30% sag and 150mm full travel the frame will rotate forwards by 2.16 (to 70.16) and 7.44 (to a gnarly 75.44) respectively. As GD states, for tapered forks the lower bearing will be external. Head tube angles range from about 66 degrees (gravity-oriented mountain bikes) to 74 degrees (razor-sharp road bikes). a perfectly-upright seat tube would be 90 and would decrease in angle as the tube tilts backward). Granted, small changes in tyre size arent going to bring about dramatic shifts in geometry, but changing wheel size certainly will. Over forking the Scout by 10mm would probably result in a similar head angle anyway. And lowering or raising your stem can help redistribute your weight on the bike. Our two seat angles, actual and virtual, are both measured from level with the top of the head tube. the bike with the 67 degree headtube angle has a 13.6 inch bottom bracket height while the 65.5 degree has a 14.1 inch bottom bracket height. But just like running different tyre sizes front and rear, theres nothing to stop you from having a 29er wheel up front and a 27.5in out back. Quick Answer: How To Measure Bike Head Tube Angle, Question: How Is Bicycle Head Tube Angle Measured, Quick Answer: How To Measure Top Tube Length, Quick Answer: How To Measure Bicycle Head Tube Length, What Factors Determine Top Tube Angle In A Bicycle Frame, Question: How To Measure Top Tube On Bike Frame. Its only about 1/180th that bad. At that time, I was trying to adapt a full-suspension trail bike into a downhill race machine. 63 degree 170/180 travel and downhill bikes too anything slacker is too slack in my experience. I then calculated where the shock needed to be mounted in order to achieve the numbers I so desperately desired. A more effective approach would be to simply lower your stem height by 5mm. The ideal head tube angle for trail bikes seems to be in the 67-68 degree range, and seat tube angles have settled around 74 degrees across the board. Let's say you have a bike with a 66-degree head tube angle and want to make it more relaxed. A couple of degrees steeper than 65 would still give some confidence compared to your current set up. >>> How to set up mountain bike suspension. Other things being equal, a bike with a steeper head angle with steer more sharply and a bike with a slacker head angle will be more inclined to travel in a straight line. A full DH bike doesn't have a 67 degree head angle. Thats all! So BB drop looks more important than seat tube angle! Measurements are rounded to the nearest millimetre. you must really be onto something here. Sep 15, 2008. Going . Gave me the sense that it had been designed to work rather than sell purely on the geo being moar slack than everyone else (looking at you every single manufacturer). Also, there are plenty of shocks that have the same eye-to-eye length, but different strokes, and by changing the stroke and travel, the dynamic geometry changes due to the increased suspension sag, even if the static numbers are identical. Slacker is better up to a point. Honestly till I started riding moto a lot I would have agreed with you. To calculate the effect of raising a stem, add 0.96cm of rise for every 1.0cm of quill . Trillion Prime 999 frame (or $1,300 USD if you can find a way to get it shipped) photo: Trillion Cycles This poll is perpetuating the misconception that HTA matters all that much, as you said its the sum of all things and the long front center that matter. 65 - 66 degrees is pretty slack for XC. Head tube angles and the changes to them in mountain bike world seem to be one of the more misunderstood concepts. Bikes with a short head tube lower the front end of the bike, reducing the frontal profile of the rider, improving aerodynamics. I suppose I could have run a lower front end to compensate but it would make it harder to lift the front end and it didn't solve the fork binding. The head angle is the angle from horizontal, to the angle that your fork sits at. The gap is closing between the like of Pole and Nicolai and everyone else. Ibis, on the other hand, is using their low offset forks to be able to run a less extreme head-tube angle: 65.9. By changing just the rear wheel, you dont get the full 19mm of BB drop that would render most bikes un-rideable, but it will lower the BB height by 10mm and chip approximately 1 off the head angle. Proud owner of a new Bronson? Slacker angles (closer to 63) are often seen on aggressive mountain bike styles such as enduro and downhill. Long seat tubes are unnecessary especially with 200mm droppers coming out. I'm 5'6" and just got on a medium Transition Sentinel and starting to set pr's on strava, I was on a 170 F/R medium Capra before, 420mm reach and 65.5 ha on the Capra vs 450mm and 64ha on the sentinel and seattube length 450 capra vs 400 sentinel. I have short legs, too, and two bikes, one with 73 degree seat tube, another with 74 or 75, I haven't been able to exactly measure, but it handles . 17 degree stems are available, this number being chosen because it will result in a horizontal set up when used with a 73 degree head tube angle, which is probably the most common or at least about the average head tube angle (90 degrees minus 73 = 17). 65-ish is for Dh race bikes. Bumping the fork travel up by 20mm, to 150mm, will slacken the head angle by approximately 1 and increase the front centre measurement by 10mm. Is there a noticeable difference in a bike with a 67 degree head tube angle compared to a bike with a 65.5 degree head tube angle. Stay in low for a slack 66-degree head tube angle. YouTube was founded by Steve Chen, Chad Hurley, and Jawed Karim.The trio were early employees of PayPal, which left them enriched after the company was bought by eBay. Reach. "Slack HTAs are only for steep tracks". That could be something as simple as the rear tyre buzzing the back of the seat tube, or something as sinister as the seatstay bridge smashing into it. Alternatively, it could be something more complex, like installing an angle-adjust headset to lengthen the front end for increased stability, or give the bike a more rearward weight bias. According to a story that has often been repeated in the . Head tube angle often shortened to head angle is measured from the horizontal to a line running down the centre of the fork steerer tube. Start with a top-down approach, as its the easiest to implement. In the example outlined above, it could also be that the rebound damping on the shock is too slow, so it cant recover quickly and actually holds the rear suspension down mid-turn. At 66 degrees, this 29er was even labeled "unridable" by some particularly vehement keyboard warriors. . Seat tube angle is the angle of the seat tube relative to the horizontal plane, measured from behind the seat tube (e.g. FoxyOne74 2 yr. ago I went from a 69 degree head tube angle to 66 this year. Affectionately known as a mullet bike, fitting a 27.5in rear wheel is a great head-angle hack on older 29ers. Geometry before travel for me. Under 66 seems fine but above that especially with 150mm forks and you are just asking for trouble. On a 150mm-travel trail bike, the variation in head angle can be as much as 8 from the fork topped out to fully compressed. Honestly till I started riding moto a lot I would have agreed with you. The current Specialized S-Works Stumpjumper is only a degree slacker, at 66.5. Reversing the process steepens the head angle and raises the BB height. My journey into understanding and adjusting bike geometry began in earnest over two decades ago. It looks cool but didn't give much confidence. Enter your email address below to receive a monthly email newsletter from MBR. I hope) I'm finding I need less and less "mechanical" advantages and am preferring a more "spicy" bike to keep the trail alive. A 67.8 degree head tube angle makes it one of the steeper on the list, but what's not steep is the $1,789.99 price tag for a complete bike with a 110 Shimano Deore drivetrain. In fact, the latest Specialized Enduro and Stumpjumper both come stock with offset shock hardware at the link end of the shock to offer high and low geometry settings. When we look at bike geometry, were looking specifically at static numbers with the bike un-weighted. That doesnt sound like much, but because the shock is leveraged, these small changes quickly add up. One way to do it would be to simply bend your arms more to help shift your weight over the front end and actively load the front tyre. And by slightly, we mean 5mm, which is less than the acceptable variation in the axle-to-crown height of a fork. The head angle is the angle from horizontal, to the angle that your fork sits at. 44mm is the internal diameter of the head tube, which obviously has to be larger than the steerer. Definition: The horizontal distance from the bottom bracket to the centre of the top of the head tube. 5 questions marks????? bike right now and it rules at resorts and full DH. Cookie Notice The TCR Advanced road race bike (we'll go with ML sizing for Giant) has a 73 head tube angle, a 45mm fork offset and 57mm of trail. The Defy Advanced endurance road bike sits between the . As well as thomson, 3t also do a 17 degree version of their arx team. I reckon I'd be quicker on a slack 6" bike than a steep 8". With 8mm shock bolts, offset hardware typically offers 2mm of offset at each end, increasing to 3mm with 6mm shock bolts. Currently on the new GT Sensor (130x130)* as my trail bike. Is a 67 degree head angle slack? And given that theres no rule about running the same tyre size front and rear, we can use this to our advantage to manipulate the numbers. Also, because fork platforms tend to span a travel range, oftentimes the exact same chassis is used from 140mm travel all the way up to 170mm, with nothing more than an air-spring assembly change. Now though, the tools at our disposal for tweaking geometry are much more sophisticated, so theres really no need to break out the Black & Decker if you want to slacken your head angle or lower your BB height. Shorter travel 65 ~130-140mm 64-63 150-170mm. 50.5 B. You also have everything else in between. And thats because there is a 19mm difference in height from the contact patch to the axle between a 27.5in and 29in wheel when both are shod with the same tyre. Experimentation is key to understanding how different adjustments impact handling, so we recommend doing it in bite-size chunks, one change at a time. or which one would be better suited for downhill, ahh sorry made a mistake read the years previous model, its actually only a half degree difference in head tube angle and same BB height. They feel almost exactly the same, geo-wise, to me except the 29er carves harder and rolls over shit faster, off camber hi lines are so much more fun now. And lets face it, no one, especially taller, heavier riders, needs to make climbing harder than it already is. So the poll stated like this makes no sense. We call these top-down changes, as they all alter weight distribution and handling without physically changing the geometry of the bike. It might not seem like much but those small adjustments, compared to a 70 degree HA/ mostly an older bike, make a difference. but it all comes down to what terrain you're on. Traditional BMX frames use a 71-degree seat tube angle, but we have found a number of frames using a 70-degree and 69-degree angle as well. And while that sounds like a tiny change, because it alters the position of the single heaviest component on the bike you, the rider youll be amazed at how big a difference it can make. Cross country bikes have steeper head angles, whilst downhill bikes have slacker head angles. For more information, please see our Weve shown how your bikes geometry influences things, now we look at how you can manipulate components and settings to improve your shape on the bike. As covered above, we do see more variation between the 29ers than the 27.5 bikes, which I found particularly interesting. How do you measure head tube width? The sharper the head tube angle, the better your handling will be. With any shock swap or reduction, including something as simple as offset hardware, always check clearance at bottom-out. I was super happy to see the numbers on that bike. So in many cases you dont even need to change your fork to increase the travel simply replacing the air-spring assembly will suffice. The angle of the head tube is related to the ground. It works much in the same way as a flip-chip, but instead of flipping the shock mount in the frame, offset shock hardware changes the effective eye-to-eye length of the shock. Saddle position and seat angle has very little impact on the overall handling of the bike, when it comes to seated climbing, fore-aft saddle position can be game changing. I more was poking at the fact we've got a chainstays thread, a reach thread and now a head angle thread all being recirculatedand they are all driving at the same thing. "get a bike to handle well". Changing the head angle will also impact steering geometry, but well save that for another time. Measure the inside diameter of your frames head tube You will need to measure (in millimetres) the inside diameter (ID) of the top of the head tube (above pic) and the bottom of the head tube (pic below). You can use one or both sets of offset hardware to fine-tune the degree of geometry change, and which option you go for will largely be determined by tyre/frame clearance at bottom-out. Major manufactures are gradually moving towards what the others have already figured out (like Pole), that the distance of the front wheel from the BB is what matters most and its a combination of fork offset, reach, and HTA that determine this. If youre still with us, congratulations, as thats a lot of tech info to digest in one sitting. One of the biggest mistakes we see taller riders make is slamming the saddle all of the way back on the head of the post to create more space in the cockpit. The problem I see is that steep head angles don't corner as well with the front end prone to folding. A 65 deg head angle on a typical hardtail will actually be more like a 67 deg full-sus . For commercial purposes, the 29er has been around much longer than the 27.5. As a rough estimate, each 20mm of travel added will correlate to a one-degree difference in the head tube angle. Shorter travel 65 ~130-140mm 64-63 150-170mm. The slacker head tube angle really only feels more challenging on switchbacks and tighter singletrack turns. Being told not to slouch in the chair is all well and good but it doesnt do much to actually change your habits. Length 1 = 90-100mm Length 2 = 100-110mm Length 3 = 110-120mm Its enough to drop the BB height by 7mm and slacken the head angle by 0.4. Does 1 degree head angle make a difference? I used to run a 62 head angle and found that on flat terrain I had to weight the front so much the rear it would slide out too easily when cornering. Head tube angle plays a significant role in how a bike handles. The slackening of head tubes over the last dozen years have wholeheartedly disproved this. Speshy's top end Epics now comes with a 66.5-67.5 HTA's. I have read the other thread about chainstays and again agree with you that short chainstays are rubbish. I'll agree if you throw a 63ish HTA on a bike that For short travel I think 63-64 is too slack for the same reason I think sub 63 is too slack for longer travel forks unless you are riding very steep terrain. Head tube angles range from about 66 degrees (gravity-oriented mountain bikes) to 74 degrees (razor-sharp road bikes). Its in the noise, however, that we can begin to manipulate the geometry. So slam that saddle forward on the head of the seapost and start to gain the benefits of a more forward riding position on the climbs. The bearing may be marked 36-45. The first number refers to the inside bearing contact with the headset race or centering cone. Depending on your frame and fork compatibility, angle sets can offer anything from +/ 0.5 of adjustment to +/ 2. Shortening the eye-to-eye length compresses the suspension linkage, lowering the BB height and slackening the head angle, without the shock actually being compressed. It just forces you to take a wider line with your front tire. What is slack, then, really? This means the fork of the bike is going to stick out farther, creating a more stable ride at high speeds, but also be slower handling. elevate the head of the bed at a 90 degree angle; and initiate a nutrition consultant for diet modification and food . These could be as straightforward as fitting smaller-volume tyres to lower the bike and increase stability. so 66 degree versus 65.5, LOL. The range of adjustment that can be achieved with offset shock hardware is restricted by the shock eyelet diameter and the size of the shock mounting bolts. The head tube angle is the angle of the head tube in relation to the ground. Designed originally as a way to tension the chain on singlespeeds that dont have slotted dropouts, the eccentric bottom bracket makes for a great geo-hack if your bike has a BB30 shell. A different tyre has also helped. Effective (HT Top): The length of an imaginary level tube extending from the center of the seat tube axis to the top of the head tube. As a general rule, you can expect trail bikes to have 64-66 head angles, XC bikes too have higher angles, enduro bikes around 63 and downhill rigs in the low 60s. Head tube angles range from about 66 degrees (gravity-oriented mountain bikes) to 74 degrees (razor-sharp road bikes). The seat tube angle can alter the overall feel of the length of the frame without changing the top tube length. And lots of bikes come over-forked as standard for this very reason. I'm riding a 65 deg. There are other variables that play into the equation. Ever get the feeling that youre hanging too far off the back of the bike mid-turn? One of the easiest and most affordable ways to adjust bike geometry is with offset shock hardware. Rolling your handlebar forward or back is another simple way to alter weight distribution without having to change the stem length or height. #15. Plonk a rider into the mix and complexity increases by a factor of 10. Love you Vital but this is kind of a funny question. Privacy Policy. Now, given that most flip-chips offer less than 7mm of BB height adjustment, it should be clear why one frame cannot be optimised for both wheel sizes. I'm not riding at the limits of the bike, not even my own limits most of the time. Very responsive, fast, maneuverable, even with a 73 degree or so, relatively laid back head tube, which would be typical of a TT or tri-bike, to keep the short wheelbase from becoming squirrely. And thats the real beauty of using an angle set; it doesnt have a big impact on BB height. Especially when a new crown steerer assembly is likely to set you back 300. That could be something as simple as changing your stem height, sliding the saddle forward on the seatpost, or bending your arms more to achieve a more dynamic riding position. Bye, Federico By rejecting non-essential cookies, Reddit may still use certain cookies to ensure the proper functionality of our platform. With this information do you think they would handle about the same? You'll usually be pretty close in estimating your head tube angle at 73 degrees (road) or 71 degrees (MTB). Brass hardware tends to be the most affordable as its soft and easy to machine, but if you want something more durable, Burgtecs Ti offset shock hardware, at 19.99 per end, is hard to beat. The head tube length is measured from the bottom to the top of the head tube. So if youre actively trying to bias the weight distribution of your bike, youll need to take the opposite approach at either end of the bike to have a noticeable impact. The latest issue of MBR is out now, and as. EG, STA and rear center plays Well that is why we stated clearly that "yes, we do realize that this question is a bit strange in isolation, given the large number of other variables in frame design and intended use and all that, but we still think there is merit to discussing it in its own right," so no bonus points to you Captain Obvious for pointing that one out. Yes, changing the geometry of your bike sounds daunting, but bear in mind that the end goal is simply to manipulate the centre of gravity of the rider. Slack Head Angles Not only does it make the suspension more progressive, to better resist bottoming, it ups the travel to 160mm and lowers the BB height by 2.5mm, so the dynamic BB height will be even lower. The slacker (lower) head angle will give slower steering response (but by contrast will be more stable). Full Member. 4. Thats because the head angle is not vertical so, the longer the head tube, the further back the top of it becomes, and so the shorter the reach measurement. . It's worth noting, though, that 29ers tend to have steeper head angles than 27.5in bikes and/or they have forks with different fork offset numbers. Standover Height: The standover height of a bike is the distance between the ground and the top of the top tube. Slacker head tube angles 63-66 degrees (DH/FR) . This means the fork of the bike is going to stick out farther, creating a more stable ride at high speeds, but also be slower handling. Otherwise, it feels 100% easier going downhills and normal on most sections of trail. If I'm comfortable with the front I ride better, the rear doesn't matter nearly as much. The 90s were a crazy time in mountain biking and custom shock links that boosted travel with no regard for leverage rate or geometry were popular. Its like trying to change how you sit at your desk. We measured our size large test bike and found an effective top tube length of 633mm and a moderate 464mm reach. My bike has 460mm chainstays, 520mm reach but I still had to ride way over the front when I had a 62 head angle when riding flat terrain. Just like that, your bike now has a 65.5-degree head tube angle. Three oclock and nine oclock offer the same range of adjustment, but instead of altering the BB height, they change the horizontal position of the BB relative the front and rear axles. This length improves comfort and increases traction for going uphill. And because the fork is angled, reducing the fork offset also raises the front end of the bike slightly. Motorbikes have more travel and thus with sag their head angles end up steeper. Balanced geometry with a 75-degree seattube angle puts the rider in a powerful pedaling position on climbs, while a slacker 66-degree head angle boosts confidence and control on technical descents. And even more so now that most forks are available in multiple offsets. There will also be an associated increase in BB height, so if the bike already has a relatively high BB, its probably better to use an angle-adjust headset or offset shock bushings. Ground-up changes act on the bike itself. I have to admit to be part of the hypocrisy: Love you Vital but this is kind of a funny question. Original cup type is not often possible, as usually ZS type change to EC type to give enough room to tilt the bearings. a perfectly-upright seat tube would be 90 and would decrease in angle as the tube tilts backward). Start customising Lets say you want to load the front tyre more to increase grip on flat corners. One of the best geometry hacks that flies under the radar, is the eccentric bottom bracket. Switching to a fatter tyre up front and a smaller one on the rear wont change the BB height much, if at all, but it will slacken both the head and seat angle a touch.
