I can get a shoelace wrapped around that contraption from here

Appears to be some sort of belted purse.

This is simple physics and 100% an incorrect way to install a rotor, assuming they intend to use it to stop the bicycle while it's moving forward and brake on the left side. Imagine the force vectors a brake applies and the constraints of material. It's quite achievable to bend or fold a rotor. It's much more difficult to expand its outer diameter. And that's exactly the directions forces are applied when the rotor is installed incorrectly vs. correctly. Not sure how that happened at the top level of the sport, but then I have worked at a "top" bike...

Mass dampers are legit, but they need to be finely tuned (weight, spring, damper) for specific oscillations and frequencies. I have my doubts whether any of that is going on in the pits. Normal mountain biking, the terrain is so varied you could never find something to work everywhere. Race track maybe? But when you see the BS mounting methods, it doesn't instill a lot of confidence in the engineering.

I know someone else has mentioned this before but some teams mounting of mass dampers is laughable. If it’s not a good positive connection it’s going to create even more vibration. Zip tied to the frame. Giant running it on the back of a plastic number boards. Flavor of the month.

You are probably definitely in the wrong thread if you think everyone should be happy with codes or saints

It’s purely a thought experiment. It seems like the trend of the last couple years for frame designers is reducing pedal kickback and/or the interaction between pedal forces and suspension movement. The prevalence of high pivots is a result of this. Taken a step further, Pivot and Specialized have done tons of work on their frame designs with 2 chain. I’m just curious if the 2 chain design could be taken even a step further if combined with an e-bike motor.

So instead of the motor driving an idler that's connected to the cassette, the cranks spin a different shaft, with a different cog on it (sorta like an idler) and that cog is connected to the cassette. I got what you were stating before, but it is basically the same. The one large challenge with the setup you are talking about is the packaging of the motor output shaft, and the sprag clutch. Ebike motors use a series of reduction gears to step down the rpm that the motor is happy (and efficient) operating at and mating that with an...

I have a question regarding the 2 chainz style drivetrains and e-bikes. I know almost nothing about e-bikes so maybe what I'm about to describe already exists. Will we see e-bikes that have a motor setup similar to the Specialized DH bike with 2 chains? Meaning, instead of e-bike motors essentially being built around the bottom bracket and using a conventional chainring to connect to the rear hub/cassette, could the motor have it's own independent drive ring/sprocket that's not connected to a chainring or centered around the BB. This could allow for different suspension layouts that perform better because designers...

Hi everyone, Andi Sykes here! I covered the China Cycle Show for Vital last week, and I've finally had time to edit some YouTube videos together of my coverage. Hope everyone is ok with me posting here, and please give me a shout if you have any questions about the bikes seen in China.

They have been using the Enduro seat stays on this and the previous iteration of the bike. Old one has sandwich hanger, new one has udh

I comment on the other site, but I draw the line at pedal assist. Once you're introducing a throttle it stops being an E-MTB and starts being a motorbike with MTB geo.

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. 🤡

Id rather read through 20 pages of brake derailment in this forum than watch that whole video at full volume.
