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 700 x 38c or 650b x 45c.
Stiffness and handling work together to ensure the bike tracks predictably and responds immediately to critical pedal and bracing inputs.

The needs and the capabilities of a modern cross country bike have completely evolved. BC40 pushes the envelope of race worthy bikes with a 66.5 degree headtube angle and 76 degree seat tube to allow you to optimize your weight well behind the front wheel for descending and further forward when climbing in the saddle.
Like all ALLIED Bikes, the BC40 is carefully crafted one frame at a time in ALLIED's Headquarters in Bentonville, Arkansas to ensure each bike is built to the highest standard of quality possible.
