BMC URS AL THREE Disc Gravel Bike
The BMC URS AL THREE Disc Gravel Bike is highly capable and extremely versatile, ready to hit gravel tracks and trails. It has ample mounts on the aluminium frame and carbon fork for mudguards and racks so you can set it up ready for commuting or adventuring. Gravel+ geometry puts the rider in an aggressive position and delivers a stable yet fun ride. Although supplied with a standard round seatpost, this can be swapped out for a dropper post if preferred, which can help you confidently tackle more technical terrain.
Shimano's gravel-specific GRX 400 components make up the drivetrain, with a wide-ranging cassette bringing a good range of gears. The hydraulic disc brakes ensure you'll stop fast on demand, whether it's wet or dry out. The bike is supplied with 45mm WTB Riddler tyres fitted to strong and durable wheels, which help to smooth out the trails for long-ride comfort.
