Best race bikes under £2,500

Race bikes are light, stiff and low. They reward a rider who can hold an aggressive position and wants the quickest bike for the money, and they punish one who cannot.

We ranked 12 bikes for this list. The order comes from the same engine behind our recommendation quiz — published stack, reach, weight, tyre clearance and gearing, never commission rates. See the method.
