7/2/2025 10:13pm Fun fact, leverage ratio is the derivative of Y wheel position with respect to shock position. You can save a lot of time spent doing equations for wheel force knowing that.

7/1/2025 11:59am It's free to use for non-commercial usage. Small businesses can get in touch for alternative pricing. Basically it's the honor system that get's audited occasionally for non-compliant usage. If you want to write your own solver I highly recommend avoiding all of the graphical approximations used and just solve the force matrix. Once you have that the antis are trivial...

7/1/2025 9:40am To my knowledge I’m the only public alternative ( https://syn.bike). Not to speak for Cascade but I believe he developed his own equation solver. You can’t model AR/AS without the shock as shock position still has an impact. Neither software effectively models flex-pivots because it requires applying a measured angular spring rate to the effective pivot. That being said, the...

6/27/2025 3:32pm The crown on Podium is hollowed out. We tested multiple variants with more and less material removed, that's how we settled on the exact amount of hollowing there is on the production fork. We refer to these holes as "lightening bores". As Charlie noted, we were chasing the sweet spot of stiffness to satisfy our pro athletes and weight was a secondary concern. Some other USD forks on the market are lighter and while they may work well for many people out there, they are not being raced by the best riders at the highest level. We chose the name...

6/27/2025 3:13pm no one is denying that the product that goes to press camps isn't dressed up for the best experience. they're just stock products, however. there's nothing special about them aside from prep, so a "camp" product feeling amazing is certainly within the capabilities of every customer fork, right? if i bought at $2000 fork and it didn't feel amazing, i'd sure be asking fox or the dealers why and would get them to make it feel that way or give me my money back.

6/26/2025 12:42pm No. Time and and time again it has been explained to you that the flex does not mean additional axle travel.

6/26/2025 12:42pm FWIW carbon fibre damps a lot more than metals. And a handlebar can also be somewhat damped 😉 Aaaand I'm out. I think we ran the course of the debate and are spinning in circles.

6/23/2025 4:35pm I think a lot of people get caught up in viewing the shock and spring as one unit. You can look at them as separate entities and the impact of a flex stay makes more sense. The total spring forcing the bike back to top of travel is the combination of the flex stay and the spring on the shock. The damper controls rebound of the entire rear end, so as long as the rebound tune is good for the combined spring rate you’re good.

6/20/2025 11:04am The talk of a flex stay rear triangle as undamped is not really true. It is only undamped in the same way that your coil spring on a shock is "undamped". Both are constrained springs; neither can move on their own without being impacted by the damper of shock. This is completely different to something like the spring effect from...

6/20/2025 8:41am This is derailing tech rumours a bit but the chattery feeling is almost certainly due to the effects on braking and not from the impact on the spring rate at the shock. Torsional revolute is the correct model but it's a fairly high rate. With a long lever arm (and a very small angular displacement) like a seat stay this...
synBike Added a reply to Have We Been Measuring Sag Wrong? (and how to fix it...)
6/16/2025 12:49pm This 1000%. Sag is a nearly useless measurement for anything other that a very initial baseline for setup on a new bike. Depending on the kinematics and dampers involved you might be anywhere from 22-32% sag between platforms with an optimum setup. The real question is not if we are measuring it correctly but if we should we be measuring...

5/29/2025 8:48pm i added to my post above with more clarification, FYI. IMO it doesn't come down to shimano (or any brand launching a product) being the problem in this case. they have a launch coming up (they said, june 5). they have to get their product and info in the right places before the launch. it's a kook or two at these places (OE, shops, brands, media, who knows) who are posting things they don't have a right to post. if shimano asks vital to remove stuff but not other outlets, it must mean our viewers are actually important 🤣

1/7/2025 1:24am You can get sealed units from Enduro in a handful of good sizes like the 7001 2RS MAX. I actually have no idea why you don't see these more; they are almost without doubt a better option for high load suspension pivots like the main pivot. They really do need some preload mechanism though so that could be part of...

1/6/2025 3:10am I believe Santa Cruz use inner seat-to-seat spacers in most applications so no preload (or based on the link tolerance so unpredictable). Once thing that Santa Cruz does perfectly is using single seal bearings and a zerk fitting to pump grease in the back of the bearing and out the seal. So much better than manually trying to clean and...
