They're all road bikes. My main commuters have been a CAAD5 'dale, an old holdsworth SS hack and my current disc-ed up Uncle John.
Well, I do 24 miles a day to work, 5 days a week and I have. From the south to the north across town everyday.
When I was doing 40 miles a day from Bath to Bristol, as I didn't have to go across town or get boiled up in the stop:start:stop wheel rims lasted 4 years and brake pad changes were so infrequent I can't recall the time period. Several months in all likely hood.
TBH I couldn't believe just how quickly everything has worn out the past couple of winters either. Its only winter TBH, December and January, sub zero, rivers of crap on the road, utterly trashed kit. This time of year I haven't done anything to the bike other than some chain lube since March.
