BMC Roadmachine 01 Four Ultegra Di2 Disc Road Bike 2020
The revamped BMC Roadmachine 01 Four Road Bike is faster, lighter and more compliant than it's predecessor. This model comes complete with a Shimano Ultegra Di2 Disc groupset. It's a bike engineered for endurance, with a whole host of features to put it at the top of its game. TCC (Tuned Compliance Concept) technology is used in the seat stays, D-shaped seatpost and fork, significantly boosting compliance while ensuring the ride remains stiff and responsive. Supplied with 28mm tyres, you can go wider still if you so wish - up to a road smoothing 33mm, while dropped, flattened seat stays bring even more benefits in terms of comfort. The geometry itself suits riders who prefer a slightly more relaxed position with a shorter reach and higher stack.
Shimano Ultegra Di2 components offer top electronic shifting performance at just a light touch of the lever. The 11-32 cassette has been paired with a compact chainset for a wide range of gears, and changes are smooth and swift. Hydraulic disc brakes provide confidence-inspiring power, even if the roads are wet. Cables are routed internally and the proprietary ICS (Integrated Cockpit System) with interlocking elements allows plenty of adjustability to stack and reach. DT Swiss ERC 1650 Spline db 47 wheels are light, stiff and strong and will have you rolling fast and smooth across even the roughest unpaved roads.
