Twostroke AL emulates the Twostroke 01’s performance in a refined Smoothweld Premium Aluminium 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. Suntour’s XCM 32 fork and a 760mm alloy bar head a part-Shimano Deore 11-speed groupset, with XCD23 wheels and Maxxis Rekon Race tires.

ACCELERATED COMPOSITES EVOLUTION TECHNOLOGIE + (ACE+)
ACE+ not only runs through thousands of virtual prototypes using Stiffness, Weight and Compliance as key influencers, but now includes a fourth key factor in the prototyping, Aerodynamics.


INTEGRATED COCKPIT SYSTEM (ICS)
The aesthetic simplicity and innovative functionality of the Integrated Cockpit is the epitome of Swiss engineering and design. ICS keeps cables and housing in their place: out of sight.


D-SHAPE SEAT POST
Improved seatpost design removing any excess materials, providing aerodynamic benefits and extra compliance.


BOTTOM BRACKET AND TORSIONAL STIFFNESS
Renowned for its power transfer, the new Teammachine SLR goes one step further with a wider bottom bracket contact area provided by the new downtube shape and the optimized carbon layup.
