Road Logic Frameset
Description
Steel road framesets occupy a narrow slice of the market in 2024, but the Road Logic has been part of Ritchey's catalog long enough to predate most of its competition. Ritchey has restarted production of its rim-brake Road Logic and Road Logic Break-Away steel framesets, and resurrected the Road Logic Disc after pausing the lineup during the pandemic. The rim-brake version covered here keeps the format Tom Ritchey has refined over four decades: a TIG-welded, heat-treated, triple-butted Logic steel tubeset paired with a full-carbon fork, sized 49 through 59cm and built for quick-release wheels and traditional caliper brakes.
The geometry is unapologetically road-race. Parallel 73.5-degree angles on average-to-larger sizes, a 72mm bottom bracket drop, 410mm chainstays, and short head tubes paired with generous top tube lengths add up to a stretched-out fit that wants to be ridden, not toured. Smaller sizes tilt to steeper seat tubes and slacker head tubes to keep the fit dialed for shorter riders, and the fork uses 46mm of rake on sizes 49/51/53cm and 43mm on sizes 55/57/59cm to keep trail consistent across the range. The handling is closer to a crit bike than an audax rig — there are no rack or fender mounts, and the riding position rewards riders who still want to get low.
Where the current Road Logic departs from its earlier self is tire clearance. Paired with a 350g Ritchey carbon fork, the Road Logic has clearance for 700 x 30c tires , which is unusually generous for a rim-brake frame and gives modern wheel-and-tire combinations room to breathe. The actual limit on most builds will be brake caliper reach rather than the frame itself, but the chainstay and fork crown were redesigned to accept wider rubber than the previous-generation Road Logic could fit....
