BMC Twostroke AL THREE 29" Mountain Bike 2022
At the heart of the BMC Twostroke AL THREE 29" Mountain Bike is its nimble and strong Premium grade hydroformed aluminium frame that encourages the rider to test their limits on fast and technical XC-style terrain. The frame has smooth welds and internal cable routing to promote a crisp and clean aesthetic, while a moulded chainstay cover and chain suck plate stop its paintwork from getting damaged.
The RockShox Judy TK R fork uses its plush, bump-smoothing suspension to tame technical trails and works in tandem with the frame via an aggressive geometry, urging the rider to attack climbs and thunder across the roughest surfaces. Bombproof, 29" wheels and voluminous, grippy Vittoria tyres grant rapid changes of direction, and the wide-ranging Shimano Deore 1 x 12-speed gear configuration allows smooth passage over all topography. Shimano hydraulic disc brakes are charged with the stopping duties and do so with confidence-inspiring power and accuracy.
Highlights
- A versatile, agile and confidence-inspiring hardtail suitable for all XC style trails
- Premium hydroformed aluminium frame with smooth welds is light and reactive
- The frame offers clearance for up to 58mm wide tyres
- Internal cable routing keeps the aesthetics clean and crisp
- Moulded covers on the chainstay, a chain suck plate and helicopter tape on the downtube protects the frame
- A RockShox Judy TK R fork cushions the trails and increases control with its plush suspension
- A 67˚ head angle, long front-end and 75° seat angle helps the rider attack steep and loose terrain with perfect weight distribution
- Strong, reliable 29" wheels and wide, grippy Vittoria tyres tame any trail
- Shimano Deore 1 x 12-speed gears are accurate and give a huge range of ratios for any terrain
- Shimano hydraulic disc brakes are precise and powerful
