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.
