SIERRA Sierra Flat Black
After another amazing year for Sergio Layos, we made a small change to make his signature frame even better. Sergio has decided to make the move back to a 75º head tube angle.
The frame features internal and external gussets, multi-butted and tapered tubing, an Investment Cast seat post clamp with the Horizontal Cut System, removable EBS style brake mounts and Investment Cast Dropouts with integrated chain tensioners!

This product is covered with Lifetime Warranty.
