In tune with the timesOur new Prorace frame made of Supreme 5 aluminium alloy is perfect for mountain biking and cross-country cycling. Its geometry is adapted and designed around 29-inch wheels from XS to XL to make it easier to tackle roots and other stony ground, as well as easy trails
Assertive choicesOur Prorace 3.9 is already solely designed for a single chainring 1x (one by) drivetrain around the new Shimano Deore 12-speed groupset. Combined with Boost technology on the fork and frame, it offers a gain in stiffness in the wheels and frame, as well as in ease of use.
A sleek designAt Lapierre, design is part of our culture. This is why, in the first Prorace model and above, the internal routing of the cables and ducts provides both an aesthetic and mechanical solution.
