Is This Linkage Fork the Future of Suspension? - Crankworx Whistler 2017
Stupid. A novel solution to a problem that doesn't exist. I don't see this design having good lateral stiffness and this just adds a bunch of pivots to wear out and add slop to the system. I want to see data on why this is better, not some dude riding it and saying "Yeah, feels good." Adding so much complexity needs to be justified, seems like they just wanted to make something different for the sake of being different

Morpheus Cycles' DJ Prototype - First Look
I'd like to see FEA on the frame, especially rear dropout area. There is a good reason why 99% of bike frames have a rear triangle where the tubes go from nodes on the chassis straight to the rear axle, not 5 in. in front of it. Way to take a steaming shit on the learning's of structural engineering Morpheus... please don't get into architecture or bridge design

Fyxation Steely HT Riser Bar 3" rise
$25 USDThe Steely HT is where you turn if you need strength and stiffness in a wide bar.
Borrowing from BMX construction, the 29” wide Steely HT is built for modern freestyle rigs. The Steely HT has a 22.2 clamp and a knurled surface to prevent slip and offers a 3” rise. Available in matt black only.
Specifications:
• Rise: 3" (75mm)
• Width: 29" (735mm)
• Clamp: 22.2mm
• Upsweep: 2˚
• Backsweep: 9˚
• Weight: 540g
WILL SELL THE STEM PICTURED FOR AN ADDITIONAL $15

a picture tells a lot. the long moment arm on the rear dropout will stress where it mounts to the frame much more than a regular dropout. why react a large torque when tubes are most efficiently used in compression and tension? I'm sure it is strong enough, but it could be made stronger or lighter by using a proper rear triangle. also fatigue life will be reduced

exactly.. why react a large moment from the when tubes are most efficiently used in compression and tension? It doesnt make any sense from an engineering standpoint

Morpheus Cycles' DJ Prototype - First Look
a picture tells a lot. the cantilever dropout will stress where it mounts to the frame much more than a regular dropout. why react a large moment when tubes are most efficiently used in compression and tension? as a mechanical engineer I dont see any engineering advantage to this design, seems like they made it worse just to be different

stupid rear dropout design... the rear tubes are used most effectively when put as close to a pure compression and tension scenario as possible. why in the hell would an "engineer" offset the rear wheel so much that there is a large moment which has to be reacted by the frame. There is absolutely no reason for this and I dont see what they are trying to do with the short rear triangle... effective CS length does not change just because the triangle is smaller
