BMC Roadmachine FIVE Disc Road Bike

Balancing performance and comfort, the BMC Roadmachine FIVE Disc Road Bike is the perfect companion for long-distance rides, yet will also happily blast around short local training loops too.

The frame uses BMC’s Tuned Compliance Concept Endurance carbon layup to carefully marry together the requirements of comfort and performance, ensuring that the frame is compliant enough for rough tarmac and sufficiently stiff to transfer all power efficiently to the rear wheel. At the front end, the Integrated Cockpit System (ICS) has a neat reverse front plate stem and ergonomic handlebar whilst at the back, the D-shaped carbon seatpost adds further compliance to the ride. Cables are routed internally once they reach the frame to keep them out of harm’s way and to help reduce drag.

Shimano’s Ultegra mechanical groupset has been the mainstay of their range for years, combining nearly all of the performance of Dura-Ace with a far more acceptable price tag. Honed to perfection through many iterations, shifting is light and accurate across the cassette and braking performance is assured from the powerful hydraulic discs. The combination of a compact 50/34 chainset and an 11-32 tooth cassette gives an excellent range of gears that is well suited to the bike’s adventurous aspirations. The wheels consist of Mavic’s ever-reliable Open Disc rims laced to Formula hubs, making a wheelset that will give years of service in any conditions.
