BMC URS Three GRX Disc Gravel Bike 2020
Don't let your bike dictate where you ride - BMC's URS Three GRX Disc Gravel Bike will excel over almost any terrain, from smooth tarmac to rutted trails, fast singletrack to long draggy climbs. Taking gravel bikes to the next level, you'll be able to explore further and roam UnReStricted with this cutting-edge frame that's well specced for performance.
Packed with technology, the frameset has a modern geometry optimised for aggressive gravel riding and a stable feel. Innovative Micro Travel Technology (MTT) adds 10mm of travel in a minimalist design, for improved power transfer and control when the terrain is at its most challenging, with a minimal weight penalty. This suspension system, together with a D-shaped seatpost and a carbon layup ensure compliance is high. The result? More comfort so you can ride both further and faster.
Aesthetically, this is a sleek looking bike, in no small part thanks to the Integrated Cockpit System (ICS). It's functional and versatile, with cables, kept neatly tucked away. Built-up with Shimano's dedicated GRX gravel components on a 1x setup, shifting across the cassette is smooth and reliable, and with a single chainring dropping your chain is far less likely. You get the power of disc brakes for stopping fast in all conditions, strong Mavic disc wheels and a top tube mount for bags and accessories. There's clearance for tyres up to 45mm wide for smooth rolling and incredible traction.
