HAUL ASS, NOT CARGO
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
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 tire maintains consistent handling by maintaining consistent trail figures.
We designed Aspero to fit most 700c x 42mm or 650b x 49mm wheel/tire combinations. Of course, there are variables—rim width, tire casing, and tread depth—which will affect final clearance. We (and the International Organization for Standardization, or ISO), always recommend 4mm of clearance between the tire and frame.
**New Shimano road (not gravel) 12 speed front derailleurs reduce tire clearance in the rear of the frame to 700x38c or 650x45b.
Stiffness and handling work together to ensure the bike tracks predictably and responds immediately to critical pedal and bracing inputs.
