The bike that made history at Leadville

Why We Love It
Inspired by the rocky surfaces, dynamic corners, and punchy climbs of Allied's legendary Back 40 trail, BC40 is a second-to-none modern XC racing bike with legs to take on much bigger trails. Its lightweight, high-performance carbon frame and progressive geometry deliver fast accelerations and race-day sharpness. Its World Cup talent extends to the 120mm suspension travel that also sets it up as a do-it-all weekend trail sled, delivering uncanny levels of control and confidence beyond its category.
