I have a pair of Mavic CXP21 wheels 700c, 32-hole (3x lacing) on my commuter road bike. For the last 3 years they've never needed truing until I finally broke a spoke with a poor attempt at bunny-hopping a pothole. The guy at my LBS says the rims are due to be replaced after he noticed some of the nipples were a little "stuck".
What criteria do you use to make this judgment?
What danger am I putting myself in by continuing to ride with them?
Can I reuse the hoops to rebuild with new spokes and nipples?
I know they're not high-end, but I'd hate to toss them if they're still good for reuse.
Thanks for your input.
