Comas 3D 20º Stem

Comas 3D 20º Stem

Description and materials
- Bike trials flat stem from young brand Comas, created by Biketrial World Champion Dani Comas.
- Developed and tested by Comas team riders Sergi Llongueras, Vincent Hermance and Eloi Palau.
- This stem is a pioneer for introducing the 20º rise instead of the common 25º or 30º.
- This allows for a riding position that best suits current frames and handlebars’ geometries.
- The stem body is 3D forged in one piece of 7050-T6 aluminium, without welds, which increases strength, stiffness and overall reliability.
- The front clamp is made in one piece and uses 4 bolts, for even and dependable clamping.
- Compatible with Ø31.8mm Oversized handlebars (most trials handlebars).
- Flat steerer clamp, with each bolt at the very end of it for uniform tightening.

· 130mm long and 20º rise (130mm x 20º).
· 140mm long and 20º rise (140mm x 20º).
