Haul ass, not cargo. In 2019, Áspero took gravel by storm. Fun, but flat out. This one keeps that brief: threaded BB, neater routing, a UDH hanger for SRAM Transmission, and a bit more aero. Three watts saved might mean one less energy gel. Worth it.
Dropped seat stays for more compliance, a slightly softer front end for late-race hours, and extra mud clearance from R5-CX and Unbound 2023. Same Áspero feel. Faster, more comfortable, more versatile.
Threaded bottom bracket. Asymmetrical T47a from R5-CX. Rider-serviceable.
Universal derailleur hanger. SRAM UDH, so you can run Transmission now and stay compatible later.
Internal cable routing. Same bearings as R5, Soloist, R5-CX, and Caledonia. Want fully internal? Grab the ST31 and HB13 from R5.
