Spotted this one in the Jan/Feb. issue of Pull Magazine: Michael Von Sothen’s custom OS20 Alpha prototype.
This rig is tricked out.
Check out this spec list (in addition to the OS20 wheels), it features:
- Hydraulic disc brakes
- Gates belt drive (with a custom split dropout)
- 20 mm axles
- One-piece CNC’ed BB junction
- 3-D headtube.
That’s a lot of stuff going on here.
