A light, responsive and strong Premium grade aluminium frame unites with a SUNTOUR XCM suspension fork to make the BMC Twostroke AL SIX 29" Mountain Bike a lively, composed and accurate ride over any XC-style trails and tracks. The frame and fork are complemented by robust 29” wheels that seemingly roll through obstacles, and high-volume WTB tyres increase traction on steep climbs and in fast corners.
An aggressive geometry positions the rider with perfect balance, allowing them to attack technical ascents and loose surfaces. The Shimano Deore 1 x 10-speed gear configuration offers a wide range of ratios so that any topography can be tackled with success, while the hydraulic disc brakes, also from Shimano, afford accurate and reliable stopping power in all conditions.
