Highlights and information
BMC Fourstroke: Cross-Country Precision Meets Trail Versatility
Wheel Size: 29" | Travel: 100mm
The BMC Fourstroke is designed for riders who demand exceptional performance on race day but also value the joy of a versatile trail bike. With its lightweight carbon frame and advanced suspension, the Fourstroke ensures optimal power transfer, precise handling, and unmatched comfort on rugged terrain. Whether you’re conquering technical racecourses or enjoying a casual ride through the woods, the Fourstroke adapts effortlessly, delivering a smooth and controlled ride in every scenario. Its refined geometry and innovative features, such as the Advanced Pivot System (APS) suspension, guarantee maximum traction and efficiency without compromising speed. The Fourstroke is a high-performance cross-country machine ready to tackle any challenge.
Why the BMC Fourstroke Stands Out
The Fourstroke is built around BMC’s cutting-edge Advanced Pivot System (APS) suspension, providing unmatched stiffness, traction, and pedaling efficiency. This system ensures that the bike excels on both technical climbs and fast descents. The lightweight carbon frame is engineered for maximum durability and compliance, while thoughtful details like integrated cable routing, chainstay protection, and fork stoppers enhance performance and reliability. With geometry designed for cross-country racing—featuring a longer reach, slacker head tube angles, and steep seat angles—the Fourstroke balances stability and agility. It even accommodates two water bottles, making it an ideal companion for endurance races and long trail adventures.
Who Should Ride the Fourstroke?
The BMC Fourstroke is perfect for competitive cross-country racers and adventurous trail riders alike.
