    Fork offset experimenting

    Yeah CSU are compatible across wheel sizes for current generation lyrik, gives a lot of options, but a bit expensive ti test haha. In fact, many variables such as wheel diameter and head angle also impacts steering behavior, a given offset doesn't yield consistent feel across different bikes...

    Pole Bikes hates Ridemonkey

    I agree with you that people should be more open to try things out without preconceptions but I don’t see it incompatible with the scientific method: build, measure, learn. The fact that theories developed from shaker rigs, wind tunnel or CFD simulation experimentation proved less effective than...

    Dumb 'New Geometry' question...

    I wasn't implying you didn't test well or anything, sorry if it came out like that! My point was that many things alter the perceived reach on a bike other than the actual reach. Just to illustrate my point with actual numbers; On a medium 2018 transition patrol with a raceface 35mm rise race...

    Dumb 'New Geometry' question...

    Maybe the way the bikes were set up was giving you a much more than the additional 5mm reach as many setup changes make a bigger impact on fit than a 5mm change on reach. It seems crazy but on the exact same bike, you can easily add 20mm of effective reach (horizontal distance from feets to...

    chains and suspension - i have questions.

    Maybe I was not clear in my first post, there will be performance change if wheel speed (not riding speed) is slow which happens quite often as you can lock up wheels riding fast in choppy terrain. So disconnecting freehub mechanism has definitely an effect, is it enough to have a big impact on...

    chains and suspension - i have questions.

    I agree that for a bump to generate pedal kickback, it is heavily situational and makes the use of pedal kickback figures mostly out of context. Cassette angular velocity caused by the various contributor of chain lengthening has to exceeds wheel angular velocity and the situation needs to be...

    Talk Me Out of a Capra 29?

    I think he is talking about a geometry number which does not exist right now, the "In context ST angle". I did not verify but I'm pretty sure he is right when saying that when you are actually climbing, his bikes are steeper than most if not at. This is because his bikes are climbing in the top...

    Talk Me Out of a Capra 29?

    I agree progression is not really meaningful. Let's take the capra 2017 vs 2018 in 27.5 The capra 2017 has ~65% progression vs ~55% for the 2018, both have ~170mm travel. What you are actually feeling is the wheel rate which is the firmness of the suspension, lower wheel rate means the...

    Talk Me Out of a Capra 29?

    Sorry if I sounded rude! that was not the goal. My comment was about you said it was sad people thought they needed such information, my point was just that it is as relevant as anything. I'm with you that between 60 and 70 % progression it's pretty much a gamble but having previous...

    Talk Me Out of a Capra 29?

    Higher spring rate and more progression both give you higher wheel rate. However, higher spring rate alone affect wheel rate across all travel range, including at top out, where you don’t often need a higher wheel rate, it also lower sag so geometry and negative travel is affected (could be for...

    Talk Me Out of a Capra 29?

    Yeah for sure, it does not mean that slower riders can't like more progressive bikes but fast, and agressive riders need more progression because they put more energy in the bike, the trail does too because they ride faster and do bigger gaps. They do need more damping too and that is taken...

    Talk Me Out of a Capra 29?

    Yeah as you said, leverage ratio impact the wheel rate by modifying both spring forces and damper forces, in contrast playing with the spring characteristics does also impact wheel rate but not in regards to damping forces. So you could basically have 2 bikes with different leverage curves but...

    Talk Me Out of a Capra 29?

    I really don't think so, wheel rate (vertical trail feel) is depends on MANY factors including frame progressivity and this is very important in most situations on a bike, even a bike travel that is so often discussed is really just a mean to alter wheel rates for a given amount of energy you...

    This is what's wrong with The Industry™

    I agree that evaluating products using a test protocol from the manufacturer of one of them make it seems like they lack independence but are you positive the test was developed by Syntace? I know Zedler also offer a multi-load test protocol. However, I think it's very nice that they make this...

    New Whip? New toys for the dependable steed?

    I too like the django with more sag and most of my non DH bike for that matter. I never got along with the % of sag, I feel that and absolute amount of negative travel would be more appropriate convention. For my type of riding, I prefer to have between around 50-70mm of negative travel...

    New Whip? New toys for the dependable steed?

    If you are talking about the Django he rode this year, it didn't have much in common with a stock bike but it was not an exercise that was part of a new chassis development. It had a 160mm lyrik, with a -2 degree angleset, longer stroke shock and machined troy links to fit the trunnion. Main...

    Shimano M820, No Chain Guide. How Risky?

    I rode my dh bike wihtout the chain guide's lower pulley for several months with no dropped chain. When the chainguide broke, I could not replace it before my race run and just decided to tighten the clutch and give it a go. It went well so I had no reason to replace the pulley.

    Bromont Lodging

    How long will you stay in Bromont? Motelbromont is good but if you plan to be a group or stay for more than a couple of days it might be a good option to look into renting a house/condo.
