Mitch Sutton
"The Roadmachine is Swiss, it's fast and it gives you a ridiculously smooth ride all day long. It's built to be big on compliance and it really does deliver on that front, and for that reason it comes into its own on those longer rides "
Mitch Sutton

The BMC Roadmachine Four is the go-to high performance road bike for the rider looking to go fast and ride all day. The Swiss designed carbon frame is a standout feature which the brilliance of the Roadmachine is built around. The Tuned Compliance Concept (TCC) improves vertical compliance by up to 25% for a silky smooth ride even on below average road surfaces. It uses ACE (Accelerated Composites Evolution) frame construction technology which delivered the ProTour-winning Teammachine SLR to minimise weight and maximise stiffness for agile acceleration and precision handling. It is equipped with a 2x11 speed Shimano 105 groupset for an incredibly swift and efficient ride, giving you a range of gears and control for any climb or descent.

The Mavic Open Disc Rims offer lightweight high-performance, helping you perform at your best for long periods of time. This bike is built to go fast and you’re going to need to control all of that speed, thankfully the Roadmachine is equipped with Shimano 105 Hydraulic Disc Brakes for excellent braking control in all conditions. The Swiss put a lot of effort into their design and concepts and it really shows on the Roadmachine. There may be a lot of technicalities to describe the Roadmachine, but what you really need to know is that it combines comfortable and efficient compliance with performance concepts that ensures this bike is built to fast and go all day long. This truly is one road bike to do it all.

About the BMC Roadmachine Range

The BMC Roadmachine is a versatile endurance machine which is comfortable even on the most gruelling rides. Recent improvements have been made to improve the range of this bike for comfortable climbing, descending and so that you can get in a swift and efficient rhythm on the flat. Already known for a super smooth ride, BMC have improved vertical compliance by a further 25% with its reinvigorated carbon frame, dropped seatstays and D-Shape seatpost. The improved compliance is matched by a stiffer bottom bracket and a 20% increase in frame lateral stiffness which ensures this bike is comfortable even when poor road surfaces mean it shouldn’t be. If you really want to take comfort to the max, BMC have created space for 33mm tyres so that you can smoothly roll on wide tyres for a crisp ride.
