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...

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...
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...

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 🤣

No chat and no discussion please, I prefer my social media experience to be unsociable, impersonal, and completely lacking in any perspective. This thread says its just for rumors and so only rumors should ever be posted here. 🤡

That "patent" alone is the best justification to burn the US patent office to the ground.

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...

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...

Designed for an OEM pre-covid so ancient history. Still do a bit of custom linkage work for various people. Using a split clamp chainstay like the Orbea Rallon (and many steel bikes) with the below bearing layout is pretty much perfect. The main axle would be torqued to basically finger tight and then locked using the split clamp. Ideally the...

From an industry perspective Enduro is almost ubiquitous for a few reasons: 1. They offer a lot of bicycle-specific sizes that can be very hard (and relatively expensive) to source elsewhere. They are one of the few suppliers with a wide range of max complement small bearings. Max complement is a big improvement in load capacity for the specific use...

Its not crazy at all to think that he is making more than an engineer at the company, almost any other sport is like this. Its just a bike company we are talking about its not like you need to pay an engineer 250K a year.

TEAMROBOT Liked a reply to forum topic How would you measure pedal kickback?

12/26/2024 12:36am
Thanks Blake, this is exactly the discussion I'm hoping to have on here. What sort of difference would you expect to see in the data? Bike using more travel, using less, more force at the rear axle, or less? My hunch is the bike with bad pedal kick will use less travel because it's getting hung up on the chain/anti-squat as it's trying to compress. (I think this would produce more measurable force at the pedals, too, because you're getting more force in your feet as opposed to absorbed by your rear spring).

The focus of this being the way they wrote the number 4 which is still a bit different and not focused on the caliper itself which is completely different is kind of funny. When are we gonna start talking about what color crayons taste best cause i feel like we are getting pretty close?

Engineers take the raw data, think through what they see, decide what is happening and make changes to the suspension. Then repeat the run and look at the data again. That's where the engineering part comes in, you interpret the raw data, you don't need the software to tell you if it is good or not. What you see is what you get and it's on you to determine if it is indeed good or bad. Having raw values at least gives you some confidence you are seeing the real thing vs. "add x clicks" where you have no idea...

Bit of a late reply but I am just seeing this thread. 1kHz is the bare minimum for linear data. Nyquist is a good start but shaft speeds can easy peak to 5m/s. to log at a positional accuracy of better than 1mm you would need to be 5khz+. That being said unless you are doing damper development where you...
