Depends what you’ve been riding. One weekend last year in Morzine with just one day of biblical rain and mud = headset, BB, forks & pivots. All needed doing. Okay they hadn’t been done for a couple of years, but all were clearly shot after that one day. The weather plus post ride washing finished them off in one go. Have to admit the provided hoses were perhaps a bit strong, though I took care not to blast any bearing areas.
This year however, Morzine again but mostly dry as we avoided the shitty day and everything’s still running smooth.
Both times though, pads gone in about a day. This time only front pads. Ride round Surrey Hills, and they last for months. It’s not the conditions, just the level of braking. Big long fast steep descents in the alps just wears them out.
