Mavic CXP 21 Rims - Any Good?(6 posts)

Mavic CXP 21 Rims - Any Good?mark_2811

I'm shopping for my first road bike and am looking at the Cannondale R700. It comes with Mavic CXP21 rims with Cannondale Expert hubs. Are these wheels any good? Alot of bikes in this price range seem to have them. Suggestions are appreciated.

I have a pair, and yeah they seem pretty indestructable, but yes again, they are also heavy. I have not been able to find any published weights on them though. Anybody know?

They must weigh in the range of 480-500 grams.

Depends on what you are trying to do.MSA

These rims are Mavic's low end offering and they seem to be mounted on every entry level bike I've seen. My own "first" bike had them with Campy 32 spoke hubs, and I bent the rear rim after only about 500 miles. Having said that, let me say that I am heavier than most riders: 200lbs, and was riding on pretty bad streets, lots of ruts etc., and at the time was putting in 100 to 120 miles week. Because of my weight I couldn't go with the factory-made light wt. wheel sets, like Kysirium or the Campy series, so I called several wheel makers, they recommended the cxp 33 rim for strength and lightness, which is what I now ride.

Are you riding for speed, racing, or fitness? How heavy are you? These are factors that will determine whether the these entry level rims will be ok for now, and what you may want to upgrade to in the future. My own bias is if you have to budget your cycling expenses, (who doesn't), the wheels are where you get the most bang for your buck in terms of improving your riding speed and efficiency.
Hope this helps.
This is what rode until last weekjtsk

The CXP21 are the wheels that came on my first road bike, Giant OCR1. I have about 5000 miles on them and the rear wheel just cracked last week. It was stress fractures on every right side spoke nipple. You cannot buy replacements for these wheel since they are an OEM wheel only. Nothing else comes close to matchging them, so if you want your wheel to match, you have to replace both of them.

Overall, they were good wheels. They are heavy. I weigh over 200 lbs. and they did okay for me. Bike says that I was lucky to get 5000 miles out of them.
