Key Features

  • In tune with the times

    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 achieve performance on easy trails.
  • Assertive choices

    Our Prorace 5.9 already solely designed for a single chainring 1x (one by) drivetrain around the SRAM SX Eagle 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 design

    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.
