TECHNOLOGY
Internal Cable Routing
Trek routes shift and brake cables through the frame to keep things clean and simple. And it looks great, too.
Suspension Lockout
Locked suspension means your fork remains inactive, increasing pedaling efficiency. Perfect for extended road sections where efficiency is more important than bump absorption.
Blendr Stem
Bontrager stem technology lets you clip your gear directly to the stem for clean looks, maximum user friendliness.
