BMC Twostroke AL Two Deore Mountain Bike 2021
With a versatile cross country inspired character, the BMC Twostroke AL Two Deore Mountain Bike is a perfect choice for any rider looking to explore a variety of off-road trails.
The frame is realised in a high grade of aluminium to deliver efficient power transfer and strength while keeping the weight to a minimum. The spritely ride afforded by the frame is joined by the composure of the partnering RockShox Judy TK fork that increases line precision across rough ground thanks to its 100mm of metered travel.
Stability, reactivity and balance are gifted by the aggressive, racing geometry while strong, 29” wheels team up with wide tyres to roll with greater fluidity across the harshest of terrain. The Shimano Deore 12-speed configuration gives crisp and accurate gear shifts while the matching Deore hydraulic disc brakes stop with power and composure regardless of trail conditions.
