ÁSPERO

HAUL ASS, NOT CARGO

We engineered Áspero for pure, unapologetic speed, ready to take down finish lines, KOMs, PRs, and FKTs. A bike built without limits, for the riders looking to test them. It’s stiff—Classics-racing stiff—and performs like you’d want a road bike to perform off-road. We think that makes sense, and it’s what we were trying to do when we were stuffing bigger tires into our existing frames and swapping in aftermarket forks to get a 40mm tire up front.

MULTIPLE CONFIGURATIONS

We designed Aspero with clearance for up to 700c x 40mm tires or 650b x 49mm tires. Of course, there are variables—rim width, tire casing, and tread depth—which will affect final clearance. We 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 700 x 38c or 650b x 45c.

TWO-POSITION ADJUSTMENT

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.

BALANCED HANDLING

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

Frame Sizing

How do I determine what bike size I need?

The age-old question, isn’t it? There are many factors that go into bicycle sizing and fit, particularly for high-performance bikes. Without being able to measure you and see you on a bike, precise fit information is difficult to supply. It’s also not unusual for someone to be able to ride two different sizes depending on their goals, flexibility, and fit tolerance. That said, we have some fantastic retailers, and we’d encourage you to go start a conversation with them about what you want from your new bike. You can find the retailer closest to you on our Dealer Locator.
