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, then controls that speed across the variable conditions gravel athletes must conquer. A machine built without limits, for the riders willing to test them.

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.

The Aspero lets you choose the tire that best suits the terrain so you're always in control, with clearance for 700x42c or 650Bx49 combinations. Since different outside rolling diameters of various wheel and tire combinations affect the bike handling, the fork includes a "Trail Mixer" design that adjusts trail to lessen the impact on handling when swapping between most common tire sizes.
