• In fact that rim has a slight notch to it between the brake track and the body of the rim. Can’t be more than 0.5mm. Is it time for a new rim? These have done 5,000 miles

  • If the brakes aren't pulsing it's probably good for many miles to come. The thing that kills carbon clincher rims IME is cooking the brake track. Structurally they're usually pretty over-engineered if you take heat out of the equation.

  • Not pulsing when braking but occasionally there’s a bit of rub when putting power through and climbing. I’ve always assumed they are very slightly out of true
