BMC URS AL ONE Disc Gravel Bike 2022
Simple and reliable, BMC's UnReStricted AL ONE Disc Gravel Bike has been designed for those who like to venture far from the beaten track. The aluminium frame and carbon fork benefit from Gravel+ geometry for stable, predictable handling off-road, with a slack head tube angle and longer wheelbase providing plenty of confidence. There are mounts for rack and mudguards along with top tube bosses and bolts on the fork legs for attaching luggage too, making the bike ideal for extended trips into the wilderness.
With tubeless-ready 45mm wide WTB Riddler tyres, rough and challenging terrain can be tackled with confidence and comfort, whilst the DT Swiss C1850 SPLINE wheelset adds reliability and strength to the set up. SRAM’s 11-speed Apex 1 groupset is a good match, offering dependable shifting across the 11-42 tooth cassette with large, easy to operate paddles and just a single ring up front for simplicity.
