The Ridley X-Fire Ultegra Di2 Bike is a race-ready cyclocross machine from one of Belgium's most accomplished cycling brands — and in a country where cyclocross is closer to a national religion than a niche sport, that means something. Ridley built the X-Fire with a single purpose: to handle everything competitive 'cross throws at it, from high-speed barrier dismounts to off-camber corners in the mud to sprint finishes that demand the kind of consistent, reliable shifting that only electronic drivetrains deliver.

The frame is built from high modulus carbon fiber, prioritizing stiffness and low weight in a combination that defines what a purpose-built cyclocross machine should feel like. The geometry reflects European CX thinking: a 72° head tube angle for quick, responsive steering; 425mm chainstays that keep the bike agile through tight course sections; and seat tube angles between 73.5° and 74.5° depending on size, keeping the rider in an efficient position when power matters. The tapered full-carbon fork — running a 1 1/8" to 1 1/2" steerer — adds torsional rigidity through the front end, which is exactly where cyclocross demands it most. The integrated seatpost is a deliberate detail: a cleaner profile with no external clamp to collect mud or complicate course-side transitions.
The drivetrain centers on Shimano Ultegra 6700 Di2, the 10-speed electronic groupset that brought precision, push-button shifting to competitive cycling. In cyclocross — where manual shifting under physical stress, poor conditions, and race-speed pressure introduces real error risk — the consistency of Di2 is a genuine advantage. Every shift is the same shift, whether it's the first lap or the last. The 46/36 FSA crankset pairs with a Shimano 10-speed cassette for a range that handles both flat-out power sections and the technical, churned-up terrain CX courses are built around. Challenge Grifo Pro tires finish the package with a tread pattern developed specifically for CX racing —…
