Key Features
Unique forming capability produces an exceptionally profiled titanium frame that delivers 30% more lateral stiffness and related performance versus leading round-tube Ti frames.
Larger reach, slacker HT angle and shorter rake contribute to optimal stability at high speed on rougher terrain, all while being easy to load the front when cornering.
Stronger and stiffer front triangle can handle the most aggressive riding. Enabled by the integration of a Rudy Ultimate fork, offering 40mm of travel, to deliver the needed compliance up front.
Optimized design accommodates tires up to 27.5 X 2.1"
Standard BB-386 titanium bottom bracket shell optimizes lateral stiffness where it counts. T-Lab’s meticulous post-machining ensures a “creak-free” ride and increase the lifespan of BB's.
UDH compatibility ensures easy derailleur replacement, smoother shifting, and better drivetrain protection.
