BMC URS One Apex Disc Gravel Bike 2021
The full carbon frameset shaves all unnecessary weight away but still possesses vast amounts of lateral stiffness for efficient power transfer and handling accuracy. This reactive and assured character is complemented by the cushioning gifted by the innovative Micro Travel Technology that is seamlessly integrated into the seat stay to seat tube junction. This suspension format affords 10mm of travel to the rear of the bike to help heighten pedalling fluidity over even the roughest of riding surfaces. Further comfort is promised by the fork and the seatpost that have tuned carbon formats to allow increase vertical flex over bumpy terrain.
The Gravel+ geometry sees a slacker head angle and a longer wheelbase give calm handling properties over irregular ground while the frameset’s tyre clearance provides enough room for wide and grippy rubber. DT Swiss C1850 Spline wheels partner with the WTB Raddler tyres to give a robust performance that’s full of traction, and the SRAM Apex 1 gears change faultlessly every time of asking. Hydraulic disc brakes stop with aplomb in any weather conditions thanks to their precise actuation and power.
