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.
FEATURES:
- 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.
- Multiple Configurations: 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.
- Balanced Handling: Stiffness and handling work together to ensure the bike tracks predictably and responds immediately to critical pedal and bracing inputs.

*In the bicycle industry, suppliers and factories sometimes change specs without notice and state that they are "subject to change without notice". This is because bicycles are made from hundreds of parts which come from dozens of vendors. Parts are sometimes updated to the most current production generation/iteration one gets better or more current parts or a comparable part. Product specifications are subject to change without notice.
