What Our Gearhead(R) Experts Are Saying:"The ASTR puts me in a position I associate with racing: low, aerodynamic, and pointed forward. On fast gravel roads that's exactly where I want to be."Why We Like ItWe built this around the SRAM Rival XPLR groupset to match the kind of riding the ASTR's geometry demands. The 13-speed 10-46T cassette is tuned for the speed range of competitive gravel rather than the wide-range climbing demands of technical terrain, and the wireless Rival levers integrate the braking and shifting into one clean, ergonomic system. Heads up! We do our best to keep bike specs and images current, but occasional component changes can happen without warning, and sometimes the photos might not show the exact build you'll receive. If you want to double-check the details, our Gearhead(R) Experts are always here to help.
