Cervelo Aspero-5 GRX RX825 Di2 Gravel Bike 2025

Designed for long, fast gravel races, Aspero-5 is for those who toe the start line with purpose, and aim to be in the group straightaway. Our engineers like to say, “if it looks fast, it probably is.” It’s a bit tongue-in-cheek, but there’s some truth to it, and Aspero-5 looks fast standing still. The cables are tucked neatly inside the stem and headtube, there’s a hint of a wheel cutout, and all of the tube shapes come from our race-proven library of shapes.
