Whether it's tearing around an XCO track or setting your personal best up a local hill, the Twostroke has you covered.
Twostroke AL emulates the Twostroke 01’s performance in a refined Smoothweld Premium Aluminum frame. Inspired by the Fourstroke and a fighter jet, it offers the perfect blend of performance, functionality and aesthetics, with radical geometry, wide tire clearance and integrated protection to combat technical terrain. SRAM NX and SX Eagle drivetrain with SRAM Level T brakes, XCD23 wheels and RockShox Judy Silver fork make a well-rounded package.
- Radial Geometry - A 67° head angle, long front-end and 75° seat angle to attack steep and loose terrain with the perfect weight distribution.
- Internal Cable Routing - Improved durability and a clean, understand look.
- Integrated Protection - Molded covers on the chainstay, an integrated chain suck plate and a helicopter tape on the downtube ensure durability and a sleek design.
- Wide Tire Clearance - Fully compatible with the new generation of wide XC tires.
