BMC Twostroke AL THREE Disc Mountain Bike
Performance, functionality, aesthetics and value combine perfectly in the BMC Twostroke AL THREE Disc Mountain Bike. It brings the design and geometry of the carbon model to a refined smoothweld premium aluminium frame, which is paired with a RockShox Judy Silver TK fork with PopLoc Remote, to soak up bumps and big hits, giving more control over rough terrain. Integrated protection over the chainstays and downtube protect the frame from chainslap and rock strikes.
There's clearance for modern-style wide tyres up to 58mm and the bike rolls on strong wheels fitted with Vittoria Barzo 2.25" tyres, an XC offering that excels on mixed terrains. Shimano Deore 12-speed components ensure smooth, precise shifts across the wide-ranging cassette, while the hydraulic discs ensure easily modulated stopping that's effective in the dry, mud or rain.
