Aspero 5 GRX RX827 Di2 1x Gravel Bike

The Cervélo Áspero-5 GRX Di2 applies Cervélo's road-honed aero program to a drop-bar frame built for racing off pavement, and the redesigned HB16 cockpit alone accounts for nearly 6 of the claimed 37-watt advantage over the standard Áspero. Shimano's wireless RX827 rear derailleur borrows its mechanism from the XTR Di2 platform, and this build pairs it with an actual XTR cassette instead of stock 1x GRX gearing. That swap opens up a 10-51T range for steep, technical climbs. A Wolf Tooth aero-profile chainring keeps the cockpit's watt savings intact despite the wider-range cassette out back.

What Our Gearhead® Experts Are Saying:

"The 10-51T range gives this build a real bailout gear most 1x gravel setups don't have, and the wireless RX827 shifts just as cleanly caked in mud as it does fresh out of the box."

Heads up! We do our best to keep bike specs and images current, but occasional component changes can happen without warning, and sometimes the photos might not show the exact build you'll receive. If you want to double-check the details, our Gearhead® Experts are always here to help.
