Mavic Reflex rims - bright spots off of spoke holes
Greetings. I have a Mavic Reflex 32h tubular wheelset. I am concerned about bright spots forming off of the spoke holes. They are forming in lines perpendicular to the spoke line. I am curious to know what causes this and whether it is a precursor to cracking. I am on the heavy side so am wondering if I should replace the rims.
Thanks in advance.
Thanks in advance.

Pics? How large are these "bright spots"? Have you tried cleaning the rims with something that reacts with the Anodized surface? [been there, done that]

I will try to post some pics later and give an idea of size. To be clear, I believe the "bright spots" to be manifestations of stress on the rim, so do not believe cleaning would help.

Its normal. The rim has deformed due to spoke tension which in turn leads to an uneven braking surface which in turn leads to the hi-low spots on the sidewall. Not a big deal.
Here's an example:

I didn't mean to imply that cleaning would be a help, but that it can be a cause. If you are talking about bright spots on the braking surface, like MJ's picture, than that's just a normal thing. I've got Mavics just like that, too.

Sorry, I did not realize cleaning could be a cause. I will post pictures tonight. These areas are not on the braking surface.

Okay. Here is a good shot showing the "bright spots" coming off of the spoke holes. They are not as bright as they appear to be in the picture - they are accentuated by the camera flash - but the picture shows the location and length of them. They are on the front and rear wheels. I would appreciate your opinions on what causes these and whether I should worry about them. Thanks.

I would tend to agree, they look like the spots you see just before seeing cracks.
my rear reflexs did not seem to last too long so I went back to '80s era box section rims.

I've got some anodized red Ritchey rims that did the same thing. I've still got the wheelset hanging in the shed, but swapped them out for a new set shortly after I saw that. My fear was they would go when I least wanted it to happen.

Thanks. I'd be interested in rims (32h) or wheelsets. Will be used with Shimano 8 speed cassette. Cheers!

I dont know if 'exploding' is imminent, just about every non-hard anodized rims does that to some extent. Are they hard anodized?
Spoke length has ZERO to do with it.

I agree the actual spoke length has little to do with this. odds are also pertty good it will not explode or suddenly come apart on your next ride. chances are yuo can ride that wheel for years depending on you riding style. just keep an eye on it and watch for cracks
