With 29’’ wheels that allow you to get over any obstacle, a comfortable and modern geometry, the Prorace has been designed and developed for cross-country trials. Rigid and precise, the aluminium semi-rigid is for novices and competition enthusiasts. It provides rigidity when picking up the pace again and steering accuracy; the Prorace 3.9 could let you gain precious minutes on your favourite routes. A true companion to push the limits. With the Prorace, wake up the competitor within you.
Our 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
Our 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.
At 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.
