Sierra Flat Black

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!

TT I Top Tube

20.8" TT is the 2019 model with 74.5º head tube angle

EBS Brake kit NOT included

Replacement stickers included
