Mavic CXP 21rims...good reputation or bad?(14 posts)

Mavic CXP 21rims...good reputation or bad?MVN
Aug 30, 2002 3:36 PM
I'm having my new bike built up next week. The price my lbs guy gave me included Mavic CXP 21 rims with Shimano 105 hubs (drivetrain is full 105). I know nothing about them so I'm wondering what their reputation is. Good or not so good? Good for heavier riders? I've dropped from 220 to 195 in the last three months (my goal is to get to 180 in a couple more months). I'm not even sure they are made any more, since I couldn't find them on Mavic's site. I'm going to be using them for training and racing until I can afford a better wheelset. I can't really afford anything else right now, so if they are not so good, I guess it doesn't really make any difference. I'll just use them until I can get something else. At any rate they'll be lighter than what I currently have. Don't get me wrong, I'm happy to be getting them. I'm just curious as to how they've held up for others. I know Mavic's reputation also. Anyway, does anyone have any opinions/advice/feedback for me? Thanks in advance.

CXP-21's didn't hold up for me but I am 6'03" and 235. Had to replace the rear wheel within 3 months.

They held up to jumping, and general abuse. But i had a bit of a flat problem running larger 36cc tire's on a cross bike. i switchedto open pro's and really likeum. Nor have i had as many problems with um.

Don't have that much experience, but I do know that my brother (~155 lbs) has broken three spokes on his CXP21s since getting into riding last summer. Me, I don't have CXP21s and haven't broken a spoke in the 15 years I have been riding...

I run 205 to 210. Got 5000 miles on CXP21s. Had to true rear wheel once. No other problems.

They're not great but will work if they fit your budget. Try to lose more weight! You should get a season out of them before they start breaking spokes. By then you will have saved up enough for some Open Pros, right. Enjoy the new bike.

you should be fine. Generally, broken spokes are not the result of the rim, rather, the quality of the wheel build itself. Obviously, rims with recessed spokes may wear on the spokes where they pass through the rim and cause failure (i.e early rolfs).

Honestly, if they are built well with 32 spokes, your weight should not present a problem . . . but less is always better.

Same situation. I weigh 195, should be down to 180 in a few months. Have a TCR 2 specced with CXP21's. No problems yet, but only been on it a few weeks. Sounds like Open Pro's are the way to go if you can afford them.

I'm on a TCR2 with CXP21s with 105 hubs. So far 355 miles since 7/3/2002 and
no problems.

I'm generally in the 220-225 lb. range, I want to drop that weight. Until then, I'm
real careful about unweighting the bike if I'm unable to avoid an obstacle.

I saw the 2003 OCR1 and it had Mavic CXP22 rims on it, so I suppose the 21s have
been replaced internally.

My understanding is the CXP21 rims were their basic OEM rims, semi aero but
not perfect.

Still, there's a courier downtown with two CXP21s on his bike and he seems to
do fine by it so they're probably just fine. I'm not having issues yet so.... there
you go.

Actually, the CXP21s are an OEM rim for new bikes. The European Mavic Tech website considers them Level 2(OEM) rims.

I had a Bianchi Veloce for about 5,000 miles with CXP 21s before I had a set of Mavic Open Pros made. They were good rims, but not great. I weighed between 175 and 185 for most of the time I was riding them. I found them fairly durable, but not as bullet-proof as Open Pros. Still, for the money they are decent rims.
I've got about 6000 miles on them...STEELYeyed

CXP 21 w/105 hubs,I have had the hubs rebuilt once and have never had a problem with with the rims. I've since upgraded to OP's w/Ultegra hubs.

The Mavic rims are great, they've held up well to a couple of thousand hard miles under my 250 pounds.
However, there is a problem with some of the spokes on the wheels. I broke a rear spoke on the wheel within a month, then another, then another, always at the nipple rather than the hub, which is an odd place. When one broke on the wheel as it sat on the LBS's workbench, the owner acknowledged there was a problem. Turns out a major supplier of spokes had over tempered a batch and they were brittle. There are a lot of them out there.
Talk to your LBS, have them contact Mavic - you're entitled to a free rebuild.

From what I've seen the CXP's 21's are kind of an OEM or stock wheel. They are known for having a questionable durabilty issue. The thing to consider is that a lot of them come on bikes that have good frames and components but have these wheels to keep costs down. People constantly want to upgrade so the wheels will match their perception of their bike and they need an excuse to retire them. They aren't the best out there nor are they the worst. They need truing more often than others and if you abuse them or ride hard or put in tons of miles they may not last as long as say open pros or kysriums. For my money I would suggest the cxp 33's. They're a little more arrow a whole lot stronger and recently there have been killer deals on them especially red. Thats just my $.01 sure wish I could find the other one
