Gravel
Factor ALUTO
2025 · 700c wheels · 6 sizes
Carbon race gravel frame from Factor, with geometry optimised around 45 mm tyres and room for up to 47 mm measured tyres at the rear and 52 mm at the front. Every size uses a 50 mm fork offset. Factor lists the 61 size with a 73 degree head angle but the same 61.2 mm trail as the 54 to 58 sizes at 72 degrees; with the same fork those two figures cannot both be right, so one of them may be a misprint.
