Product Description

Welcome to the era of speed in gravel. The 2021 Cervelo Aspero GRX 810 1X Road Bike is for the new breed of rider that is emerging - the one who loves the freedom and exploration that gravel culture was founded upon but who has a hunger to ride wild, to go full bore, and to explore not just geography but personal limits. This frontier requires a new kind of gravel machine, one engineered not to roam the trails, but to slay them. For these athletes, Cervelo created a machine engineered for pure, unapologetic speed, ready to take down finish lines, KOM leaderboards, PR’s, and FKT’s. A single bike that first generates maximum speed and then second, controls that speed across the variable conditions gravel athletes must conquer. A machine built without limits, for the riders willing to test them.

  • Aspero Adapts: Different outside rolling diameters of various wheel and tire combinations affect the handling geometry of the frame. If the tire size is altered without acknowledging the effect on trail, the result is wild swings in handling - faster or slower - from the design basis trail value, which is problematic for high-speed control.
  • It’s time to change the paradigm of gravel bike design from hauling gear slowly to empowering athletes quickly. Leveraging vast knowledge from road racing, the Aspero frame is designed with world tour stiffness for greater pedal power transfer, using less and lighter material to aid climbing and accelerating, while maximizing speeds with aerodynamic shapes critical to efficiency at speed.
  • Multiple Configurations: Bike adjusts to different wheel/tire combinations to maximize control. Cervelo engineered the bike to fit most 700x42 or 65x49 tire/wheel combos comfortably. Of course, there are variables - rim width, tire casing / tread depth - which will affect final clearance. There should always be 4mm of clearance around what is installed on the bike.
  • Two Position Adjustment: Trail - front wheel response to rider input - is the most critical factor in high velocity handling. The ability to adjust trail with the two-position “Trail Mixer” to compensate for the extreme range of tire sizes ensures a uniform ride experience.
  • Balanced Handling: Stiffness and handling work together to ensure the bike tracks predictably and responds immediately to critical pedal and bracing inputs.
