Falcn Shimano 105 DI2 // 2x12s

The Ridley Falcn platform is the brand’s modern all-round race bike, designed to bridge the gap between the Noah aero bike and the Helium climber. Rather than chasing one extreme, it combines a heavily aero front end with a lighter, more balanced chassis intended for fast road racing across varied terrain. Ridley positions it as an “aero-to-weight” bike, and that description fits: this is a disc-brake race platform built for riders who want one bike for bunch racing, hard rolling terrain and rougher road surfaces, rather than a dedicated aero or featherweight specialist.

A defining part of the Falcn’s identity is its aggressive fit and contemporary race-bike packaging. The front end is notably low for the category, and the frame is shaped around modern performance priorities, including 34 mm tire clearance and details such as the diffuser fork crown and UDH compatibility. Within the range, the Falcn RS sits at the top with Elite carbon construction and a D-profile aero seatpost, while the standard Falcn uses Essential carbon and a round 27.2 mm seatpost. Both share the same performance geometry and core handling intent, making the distinction more about material level and finishing details than a change in the bike’s role.

Fit and geometry

The Falcn’s geometry points clearly to race handling and an aggressive position. In size M, the bike pairs a 551 mm stack with a 397 mm reach, which is low and purposeful for an all-round road race bike rather than an endurance-oriented design. Across the size range, the front end stays relatively low—530/388 mm in S and 573/404 mm in L—supporting a stretched, aerodynamic riding position. Head tube angles range from 72° in XS to 74° in XL, with 73.5° in both M and L, which is in line with modern performance road handling rather than ultra-stable endurance geometry.

Ridley keeps the rear center tight and consistent with 407 mm chainstays in every size, helping preserve responsive acceleration and direct cornering feel. Wheelbase grows moderately from 974 mm in XS to 1012 mm in XL, so the bike should retain a quick, race-bike character without becoming nervous. The seat tube angle steepens in smaller sizes, from 72.5° in L/XL to 74° in XS, a common approach to keep rider position consistent across the range. Combined with BB drop figures of 68 to 75 mm, the geometry suggests a bike that is meant to feel planted enough for fast road racing while still prioritizing sharp reactions and a low frontal position.

Builds

The Falcn range is offered with a broad spread of drivetrain options, covering premium electronic race builds down to more accessible mechanical specifications. At the top end are Shimano Dura-Ace Di2 2x12 and Shimano Ultegra Di2 2x12, aimed at riders who want a full modern race-bike build with flagship or near-flagship shifting. Shimano 105 Di2 2x12 gives the platform a more attainable electronic option, while Shimano 105 2x12 provides a mechanical entry point without changing the underlying race-bike concept.

Ridley has also expanded the lineup with SRAM options for 2025, including Rival AXS 2x12 and Force AXS 2x12. That gives buyers a clear choice between premium wireless SRAM builds and Shimano’s electronic or mechanical ecosystems. While detailed wheel and finishing-kit specifications are not provided here, the overall build spread shows Ridley positioning the Falcn as a race platform available at multiple price and component levels, rather than as a single halo-only superbike.
