BMC URS 01 ONE Gravel Bike 2022
Sitting at the top of BMC's UnReStricted range, the 01 ONE Gravel Bike benefits from a premium quality carbon frame, top-tier components and SRAM’s finest electronic groupset.
Differentiating it from most gravel framesets, the UnReStricted 01 ONE has an elastomer in its seatstays that provide 10mm of micro-suspension. This is enough to add a little bit of extra comfort but also helps a lot with traction and control off-road, keeping the rear tyre in contact with the ground for better grip. The bike’s modern geometry is equally helpful, with a slack, 70° head tube and long wheelbase for more stability and confidence when things get tricky.
Mudguard mounts, rack points and bosses for a top tube bag extend the bike’s remit to longer trips when the potential to add a hub dynamo light might also come in very handy. BMC’s Integrated Cockpit System helps the bike’s svelte looks by hiding the brake hoses away in the stem and more exposed sections of the carbon frame are covered by sturdy protectors.
SRAM’s proven RED AXS groupset with its innovative ratios and intuitive operation is a great match for this top-end build. The 10-52 Eagle cassette ensures a huge range of gears are available via the large paddle shifters and the fully wireless design means that there is never an issue with cable stretch or dirt fouling the shifts. RED hydraulic disc brakes offer fantastic power, reliability and consistency whatever the weather.
Lightweight ENVE G23 wheels with WTB Raddler tyres complement the bike’s performance perfectly, rolling rapidly over the ground and gripping tenaciously in a variety of conditions. Both the wheels and the tyres are tubeless-ready, so offer better puncture protection, comfort and traction off-road.
