Recently, my rim collapsed from being worn through after a few years of braking.
I've bought replacements but it's brought me to wonder how long cyclists ride their bikes before replacing them.
Racers seem to replace their bikes each year, recreational every few years, and commuters when things break and replacement parts can't be found (my rear triangle spacing - 126 mm - limited my wheel choices, I did find a screw on freewheel wheel with a 126 mm spacing - I was thinking I was looking at a 130mm spacing for 7 spd cassette, 135mm for 8 spd cassette)
My last commutter I put about 50,000 kms on over 11 yrs before I replaced it and my current Cannondale I've put 20,000 kms on over 6 yrs. After 4 or 6 more years, I'll be out of replacement 7 spd cassettes and I don't know if I could spead my rear triangle to accommadate and new and wider hub for an 8 or 9 spd cassette so I'll be looking at replacing it after maybe 12 years and 40 - 50,000 kms.
How many years and/or kms (miles) do you go before you replace your old bike?
