Best race bikes under £4,000
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 36 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.
Our pick
Canyon
Ultimate CF SL 7
A proper lightweight climbing bike at a price that used to buy alloy. Aggressive — you need the flexibility for it.
Why it wins
- a race bike is the right tool for the riding you described
- 7.6kg and a racier position make it quick when you push
- 7.6kg with a 27in bailout gear for steep climbs
If you want to spend the whole budget
Our pick above wins because it balances how well the bike suits this riding against what it costs — which often means the answer is not the most expensive bike you could buy. If you would rather use the full £4,000, this is the one to get.
Canyon
Ultimate CF 7 AXS
Fifth-generation Ultimate CF with wireless Rival AXS, a 10-36 cassette, 50mm carbon wheels and 28mm tyres.
