I am still using my front rim, purchased in 1994. The rear finally cracked in 2008. Have to be over 50000 miles.

>> Thank you for being so prompt. I can understand rimwall wear on the back tire but this failure of the rimwall was on the front which I hardly ever use. Also, my bike only has about 1000 miles (it could easily be less - my odo has less than 700 on it.) My tires are just coming to the place where I am thinking about replacing them. I do not think it is normal to have to replace the rims as often as you replace the tires. I am still on my first set of break pads and they have a lot of wear left. How could a metal rim wear out faster than the pads?

>> On my back rim - the first that went - there was a clean break at the weld point and the rim was plenty thick there.

>> I also think that Bike Friday, at least on YAK, should put out a general warning that people who bought 3-5 years ago (or whenever this problem seems to have appeared) should check their rims carefully.
