BMC UnReStricted LT ONE Gravel Bike 2022
As well as the Tuned Compliance Concept Gravel carbon frame, the 10mm of Micro Travel Technology makes a very noticeable difference to the ride, in terms of both comfort and traction on bumpy climbs. Similarly, the fork has 20mm of suspension that has been specifically tuned for gravel riding, adding lots of control without detracting from the bike’s efficiency. When added to the 42mm of tyre clearance, there is plenty of scope for this bike to tackle terrain far outside the usual gravel bike remit.
The geometry has been developed to complement the bike’s capabilities, with a slack, 70° head tube angle and long wheelbase for stability whilst mudguard and rack compatibility further increase the bike’s versatility; there is even cable routing for a dynamo light hub for extended adventures.
Without any gear cables to stretch or get contaminated, the shifting from SRAM’s 12-speed Force eTap AXS drivetrain is fantastically fast and reliable, with large levers that are easy to hit on bumpy trails. Light 700c carbon wheels and 40mm WTB Raddler tyres combine to give the bike a nimble, fast-rolling feel and as both are tubeless-ready comfort, grip and puncture resistance are all increased.
