BMC Roadmachine Three Ultegra Disc Road Bike 2021
A speedy but composed ride that lends itself perfectly to the most challenging and enduring parcours is given by the BMC Roadmachine Three Ultegra Disc Road Bike thanks to its carbon construction, comfortable geometry and reliable components.
The frameset has a full carbon construction, and this bestows high levels of pedalling efficiency while still keeping the weight low. Comfort is infused by the frame’s seatstays, the fork and the seatpost that all have their carbon layups manipulated by BMC’s Tuned Compliance Concept to afford greater levels of lateral flex over poor road surfaces. The endurance inspired geometry of the frameset shortens the reach and increases the height of the handlebars to create a more relaxed position, which, in turn, lowers rider fatigue on longer routes.
The frameset’s ample clearance accepts wider, plusher and quicker rolling tyres and the Shimano RS-370 wheelset is light for climbing, strong for tackling rough roads and is tubeless-ready tyre compatible. Gear changes are slick and reliable thanks to the Shimano Ultegra setup and the partnering hydraulic disc brakes, also Ultegra, give reliable stopping power, even in the teeming rain.
- A high performing endurance inspired bike that blends sublime levels of comfort with speed to become a true all-round performer across any road terrain
- The full carbon frameset is light but laterally stiff for efficient power transfer
- The frame’s seatstays, the carbon fork and the carbon seatpost are manipulated by BMC’s Tuned Compliance Concept to afford rough road cushioning without sacrificing power transfer
- An endurance inspired geometry is slightly shorter and higher to lower fatigue on long rides and has a longer wheelbase for more composed handling
- Tyre clearance for up to 33mm gives the potential of lower rolling resistance and increased comfort
- Shimano RS-370 wheelset is light, robust and tubeless-ready tyre compatible
- Shimano Ultegra gears shift with accuracy and dependability
- Shimano Ultegra hydraulic disc brakes stop flawlessly in all conditions
