TheKaiser Added a reply to Nerding out on Brakes shall we? Not another tech deraliment
5/20/2024 2:27pm Are you saying that the flexed piston seals, which would normally roll back the pistons when the lever is released after a short pull, will slowly creep back along the piston under a long sustained pull as is done by strapping the lever down for an extended period? So it is kind of like advancing the pistons by squeezing the...

5/20/2024 2:20pm I have heard that rational before regarding keeping the system pressurized helping rid it of bubbles, and I just don't get how that would be helpful. In my experience, the opposite is what you want, as with a vacuum bleed the bubbles expand hugely and therefore have greater buoyancy. Going up/down in pressure rapidly could maybe help, as can vibrating...

5/3/2024 11:36pm Thank you for posting that master cylinder bore info! Companies frequently publish and even tout their caliper piston sizes as a feature but I haven't ever seen the equivalent for master cylinders leaving a big "?" when it comes to determining actual hydraulic leverage.

5/3/2024 11:27pm Wow man, I've just been catching up on this thread, great work on your fork! From the vids the newest revision looks to be working beautifully. I remember the twin shock Cannondale DH bike that had a similar "travel envelope" that was measured in square inches rather than linear inches, and it always seemed like a neat idea even if...

4/26/2024 1:07pm Do any of you peeps know if those Lewis brakes, that Intense is now using, have the same cylinder sizes in the lever and calipers as the Trickstuffs they are copying? I am curious if they have the same hydraulic leverage, or did they just copy the look while going for different mechanical advantage?

So I have two frames, one is a chinese open mold, and boy have those come a long way in the last few years. Geometry is close enough, and they seem well built. However, its still chinese open mold, so internal headset routing (I can't express how much I hate this now that I own one), no UDH, terrible internal cable routing, bolts keep coming loose even with locktite, not enough rear shock clearance, etc. However, when its working it rides excellent. Here is a good place to start on building your own: https://www.emtbforums.com/threads/m820-bafang-cef50-frame-lightweight… My other frame is a ebike-version...

11/21/2023 1:28am Hey Ham, Your Bafang build sounds really interesting. I've mostly seen their hub motors, but recently came across their mid-drive motor on the new Vitus MTBs, and I dug the promised serviceability and lower entry cost, although that Vitus is somewhat of a tank. From what you're describing though, it sounds like you built yours up from scratch, using an...
