I've just had to replace the bottom bracket on my 'summer' bike. It's spent the last three rides pinging and clicking every time I stand on the pedals.
It's a Dura Ace 9100 and I would guestimate it's done about 2000 miles.
The bike's fixed gear so admittedly the BB probably has a harder time but this still seems like a bit of a short lifespan. Prior to this I've only really used cup and cone for any length of time which with yearly maintenance outlasted all the bikes they were fitted to.
This bike never gets jet washed but obvously living in England even the odd Summer ride can result in unexpectedly getting absolutely soaked from time to time.
Wondering what peoples experiences are here of outboard BB's? Have they really become such a disposable commodity?
