Do Deliveroo and many runs around thr city with some load on, city made of potholes and diesel coated cobbles, so 23c doesn't really cut it, tried very hard to survive on <28 but gets old quick lol
I've time trialled on 28s for the last 6 or so years so I had no qualms throwing the fattest rubber I could on my commuter/training bikes. 2.3" balloon tyres on the Inbred, 32mm on the Kinesis, 28mm on the Tarmac (actually it has 25 but that was from a race and I need to swap wheels).
