Factor ONE
2025 · 700c wheels · 5 sizes
Factor's aero race bike, built around the latest UCI rules with long reach and an integrated one-piece bar with no separate stem. Factor quotes a seat tube angle range of 73.5 to 77 degrees through seatpost adjustment; the figures here are the nominal angles. The 47 uses a slacker head angle and a longer fork offset to keep trail close to the larger sizes.
