Cervelo Aspero GRX RX925 Di2 - 2027
Description
The Ultimate Gravel All-Rounder
Áspero remains true to its original brief, but with some improvements: a threaded BB shell, neater cable routing, and a UDH-compatible derailleur hanger for those who want to use SRAM’s Transmission drivetrains. And it’s more aero, of course. In the case of Áspero, aerodynamic performance is less about pure speed as a result of drag reduction, and more about conservation of energy.
After a big day in a headwind, the three watts saved over the previous Áspero might add up to one less energy gel your stomach has to digest—WORTH IT.
