The BMC 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.
SRAM’s SX Eagle 12-speed groupset and Level brakes are matched with a Suntour XCM 32 fork, XCD23 wheelset and Vittoria Barzo tires.
