Cervelo Aspero 5 GRX Di2 Gravel Bike 2025
Some might say aero doesn’t matter on a gravel bike, but if you’ve battled a headwind across an open prairie, the thirty-two grams of drag you’ll save with the Aspero 5 GRX Di2 Gravel Bike come as a welcome respite. Most gravel racing is done without the benefit of a World Tour peloton or World Tour tactics, and when it’s your nose in the wind all day, it’s nice to know your bike’s shouldering a bit of the load.
Trail front-wheel response to rider input is the most critical factor in high-velocity handling. Flipping the two-position "Trail Mixer" to compensate for the difference in circumference between a 650b and 700c tyre maintains consistent handling by keeping trail figures stable.
We designed Aspero with clearance for up to 700c x 40mm tyres or 650b x 49mm tyres. Of course, there are variables—rim width, tyre casing, and tread depth—which will affect final clearance. We (and the International Organisation for Standardisation, or ISO) always recommend 4mm of clearance between the tyre and frame.
