BMC UnReStricted 01 THREE Disc Gravel Bike 2022
The BMC UnReStricted 01 THREE Disc Gravel Bike uses all of BMC’s road racing knowledge and applies it to the world of gravel bikes, ensuring a fast, high-performance ride with enough comfort for long off-road adventures.
MTT (Micro Travel Technology) adds 10mm of suspension to the rear of the bike, ensuring that the rear wheel remains in contact with the ground for better traction and control along with protecting the rider from any bumps. The carbon layup also contributes to the bike’s comfort as does the D-shaped carbon seatpost, both of which help to reduce the transmission of vibrations through the bike. Handling-wise, the long wheelbase and slack head tube angle give plenty of confidence and stability whilst the geometry also places the rider centrally over the bike for more balanced weight distribution. The frame also features mounts for racks and mudguards, greatly increasing its versatility.
Fully wireless, SRAM’s fantastic 12-speed electronic Rival eTap AXS drivetrain provides instant shifts from just a light touch on the large paddles, moving the chain across the wide-range cassette effortlessly. The hoses for the hydraulic disc brakes run internally through the stem and into the frame so they won’t interfere with any luggage. Both the WTB Raddler tyres and DT Swiss G1800 Spline wheelset are tubeless-ready in order to take advantage of improved traction, fewer punctures and more cushioning that use without inner tubes can bring.
