Start your dream mountain bike build with BC40’s frameset. It’s the perfect canvas to create your one-of-a-kind ride with custom components and head-turning custom paint.
BC40 was born in the OZ and tested against the endless singletrack we’re lucky enough to call our backyard. But we didn’t design it just to flick around local tracks. We designed it to conquer Leadville, the world-renowned Race Across the Sky. And it did, setting the new women’s course record in 6:48:55. Race. Play. BC40.
Inspired by the rocky surfaces, dynamic corners, and punchy climbs of our 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.
World Cup athlete and World Champion Kate Courtney trusts BC40 to race to peak performances every time she takes to the start line. And no matter the build you chose on your BC40, you’ll experience the same high-performance frame ridden by the world’s best.
The BC40 is now 100g lighter than before. In fact, by optimizing its carbon laminate schedule to carve out any excess weight, we’ve made the frameset stiffer all around, too, without sacrificing any of BC40’s renowned strength. That means all the power you’re putting down gets into the ground as you fly up the climbs.
