BMC Roadmachine FOUR Road Bike

The Roadmachine brings big tire capabilities to its proven endurance platform to make every ride better. Built with Shimano’s 105 Di2 groupset and fitted with road-smoothing 30mm tires on a set of Mavic Open Disc wheels, the Roadmachine FOUR also features many of our innovative technologies, such as a Premium Carbon D-Shape seatpost to ensure next-level compliance and integrated downtube storage for peace of mind.

DOWNTUBE STORAGE WITH INTEGRATED BOTTLE CAGES
We obsessed every detail of the downtube to optimally integrate internal storage. Inside, there’s a purpose-designed water-repellent pouch for on-ride carry. Neatly sealed under drag-reducing bottle cages.

FENDER MOUNTS
Our most winterproof bike is full-fender compatible, featuring mounting points on fork and frame for bolt-on fenders, plus BMC designed D-fender compatibility for the most simplified and lightweight approach to reducing road spray.

TCC ENDURANCE
The Roadmachine takes our TCC Endurance vision further with big wheel capabilities, a dropped BB, adapted head tube angle, increased stack, and one of the industry’s smallest rear centers for a responsive ride.
