Van Rysel RCR Pro Ultegra Di2 Bike

The Van Rysel RCR Pro Ultegra Di2 Bike is what happens when an aerospace laboratory and a cycling brand share a neighborhood. Van Rysel's design headquarters sits in Lille, France — meters from the ONERA laboratories, The French Aerospace Lab, where engineers work on fighter jet aerodynamics. The two teams collaborated directly on the RCR Pro's frame geometry and tube cross-sections, calculating every profile for maximum efficiency across the primary wind angles experienced in racing. The result is a bike in the lightweight-aero category: a frame that weighs between 740 and 790 grams depending on size, a 380-gram fork, and aerodynamic shaping that doesn't require trading away the weight savings that make this bike fast uphill as well as on the flat.

The frame uses Super High Modulus carbon — Van Rysel's top-tier fiber specification, chosen for its exceptional stiffness-to-weight ratio over standard high-modulus options. The tube profiles are optimized for the ±15° wind angles where real-world racing happens, not just for the drag measured in a dead-on headwind. Tyre clearance extends to 33mm, which means the RCR Pro works with wider rubber without any frame compromise. This is the bike that the Decathlon CMA CGM WorldTour team races on, developed in direct technical collaboration with those riders and proven across the full UCI circuit calendar. Van Rysel makes no distinction between the bike their athletes race and the one they sell.

This build pairs the RCR Pro chassis with Shimano's Ultegra Di2 groupset — electronic shifting across 12 speeds, hydraulic disc brakes, and a power meter integrated into the Ultegra R8100 crankset. At $6,999, having a power meter come standard rather than as an add-on is a meaningful difference. The crankset runs a 52/36 chainring setup against an 11-34 cassette, giving you range for steep climbs without surrendering the top-end gearing for flat race situations. Shifting is handled by Shimano's Ultegra Di2 R8170 levers — the same generation used by riders who want Dura-Ace performance at a measurably lower price.

Swiss Side Hadron² Classic 500 Wheels

The wheel spec is one of the most notable things about this build. Swiss Side's Hadron² Classic 500 are 50mm deep carbon clincher wheels — hook construction designed to balance rolling resistance and aerodynamic performance across varied terrain. The rim profile at 50mm sits in a range where aerodynamic gains are consistent without the crosswind handling compromises that come with deeper sections. These are the same rim shapes as Swiss Side's Ultimate series, paired with DT Swiss hubs and spokes. They're not a budget concession — they're a deliberate spec for a bike designed to win road races.

Cockpit and Contact Points

The cockpit is a Deda collaboration: Deda Van Rysel Superbox EVO stem and Deda Superzero RS handlebar, an integrated combination developed specifically around the RCR Pro's head tube and aerodynamic intent. Bar width and stem length are size-matched — 40cm bars on XS and S, 42cm on M and L, 44cm on XL, with stem lengths ranging from 80mm to 120mm accordingly. The saddle is a Fizik Antares 140mm. Tyres are Continental Grand Prix 5000 S TR in 700x28, tubeless-ready out of the box — one of the best road tyres available in any category, and the right choice for a bike designed to be ridden hard.

Final Take

The Van Rysel RCR Pro Ultegra Di2 is a WorldTour-grade carbon road bike at a price that makes it genuinely accessible. The ONERA aerodynamic development, the Super High Modulus carbon, and the Decathlon CMA CGM racing pedigree are not marketing additions to a production frame — they're what the bike actually is. The Ultegra Di2 build adds a power meter, Swiss Side 500 wheels, and Continental GP 5000 S TR tubeless tyres to a chassis that competes at the highest levels of the sport. Available in sizes XS through XL.
