To optimize the fit of your CIRCA, we offer 4 geometry types: 1. Standard, 2. Short Reach (for riders with long legs), 3. Long Reach (for riders with long torsos) and 4. Full Custom. Our standard frame sizes fit about 90% of the population, while Short Reach and Long Reach geometries take care of almost everyone else. Our Full-Custom option is also available when necessary. All of our frames have ride characteristics that blend stability, efficiency and all-day comfort.
For those who want to leave the pavement behind, our frames max out at 35c for a 700c wheel and 38c for 650b in the rear triangle. Tires up to 45c can be run on the front if desired.
