BMC Twostroke 01 FIVE Disc Mountain Bike
BMC's Twostroke 01 FIVE Disc Mountain Bike is an aggressive hardtail XC bike that excels on a range of terrain. The progressive geometry is confidence-inspiring on steep sections and loose surfaces, perfectly distributing weight through a 67° head angle, long front end and 75° seat angle. The Twostroke 01 premium carbon frame incorporates Tuned Compliance Concept (TCC) XC, which brings tuned vertical deflection to smooth the roughest trails, allowing you to push harder on the pedals. A RockShox SID Select fork with OneLoc Sprint Remote does a good job of soaking up bumps and hard hits, improving control when things get rough.
Integrated covers protect the frame from rock strikes and chain slap, and all cables are routed internally, reducing contamination and enhancing aesthetics. The frame is also compatible with a dropper post if preferred.
A mix of SRAM Eagle 1x components delivers smooth, precise shifting and powerful braking. Clutch technology in the rear derailleur stabilises the chain, and a 10-52T cassette provides a huge range of gears to assist you up steep or tricky climbs. DT Swiss XR 1700 29" wheels fitted with Vittoria Barzo tyres ensure smooth, fast rolling and excellent traction.
