ASTR RS Gravel Frameset

What Our Gearhead® Experts Are Saying:

"I’ve raced the ASTR RS across fast gravel courses, and it’s an absolute missile. It feels planted at high speeds but accelerates like a pure road racer. The aero shaping and fork diffuser make a real difference on open sections, and the 52mm clearance gives me the freedom to pick my tires for the terrain. This frameset is made for riders chasing podiums and KOMs alike."

When we’re chasing speed over rugged terrain, the Ridley ASTR RS Gravel Frameset delivers the performance edge we need. Designed from Ridley’s Elite Series carbon—crafted with a precise blend of 60T, 50T, 30T, and 24T fibers—the ASTR RS is impossibly light, weighing just 890 grams without compromising stiffness or aerodynamics. Every contour of the frame, from its slender seat stays to the integrated fork diffuser, is tuned to slice through the wind while keeping us stable on unpredictable courses.

The geometry is race-ready yet composed: a 71.5° head angle for quick handling, a steeper 74° seat tube for explosive climbing power, and a slightly lowered bottom bracket for high-speed stability. Combined with class-leading 52mm tire clearance, the ASTR RS redefines gravel performance—blending road-race sharpness with off-road capability. When we’re looking to build the fastest, most capable gravel machine possible, this frameset is where it all begins.
