Welcome to the era of speed in gravel.

A new breed of rider is emerging-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, we 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.

Ideal For: Gravel racing, from endurance to gravel enduros

Handling / 1 of 2

Multiple Configurations

Bike adjusts to different wheel/tire combinations to maximize control. We engineered the bike to fit most 700x42 or 650x49 tire/wheel combos, comfortably. Of course, there are variables - rim width, tire casing / tread depth - which will affect final clearance. IMPORTANT NOTE - We always recommend there to be 4mm of clearance around whichever tire/wheel combo is installed on the bike.

Handling / 2 of 2

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.

Haul ass, Not cargo.

Road racing inspired. Gravel racing refined.

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.

Balanced Handling

Stiffness and handling work together to ensure the bike tracks predictably and responds immediately to critical pedal and bracing inputs.

  • The fork's Trail Mixer adjusts trail to lessen the shock to handling when swapping between most common tire sizes.

The Aspero lets you choose the tire that best suits the terrain so you're always in control.

  • Clearance for 700x42 or 650Bx49 combinations
