Description

Steel frames carry a certain mythology in cycling, but the Ritchey Road Logic earns its reputation through geometry and construction rather than nostalgia. Tom Ritchey's design philosophy centers on triple-butted Logic steel tubing—thicker at the joints where stress concentrates, thinner in the middle spans where weight can be saved without sacrificing durability. The result is a frameset that weighs less than many riders expect from steel while maintaining the road feel that keeps devotees loyal to the material.

The geometry reflects decades of refinement in what makes a steel road bike handle correctly. A 73° head tube angle on the size 53 pairs with 46mm fork offset to produce predictable steering that tracks through corners without nervousness. The 72mm bottom bracket drop positions riders low enough for stability without sacrificing pedal clearance. Chainstays measure 415mm on sizes 53 and up—long enough to smooth out road imperfections while keeping the wheelbase manageable for responsive handling.

Frame details signal the intended build direction. The straight 1-1/8" head tube accepts threadless stems without requiring proprietary components. Routing accommodates both mechanical and electronic drivetrains, and the rear spacing works with modern 130mm road hubs. The included Ritchey WCS Carbon Road fork saves weight where rotating mass and steering feel matter most, while the steel frame handles the compliance work through natural material characteristics.
