I'm a bit baffled by it too. As mentioned above, i'm 76kg and they are set up right with front toed in slightly. they stop better than any brakes I've had before, but chews through the pads like they're made of jelly baby.

Are you using Exalith pads?

yep

I had the same issue when I first bought my wheels. I went through about 2 sets on the front before I learnt that it really helps to wind the brake pads back off the rim a touch (so you have more travel in the brake lever) I think I was subconsciously using the brakes more than I thought and it doesn't help to have the pads so close to the rim.

Also try using a beer mat (the width of one seemed to work for me) behind the fork and toeing in the pads. The squeal doesn't last long if you toe them in correctly.

I've had the same pads on the front for around 9 months and barely any sign of wear. The rear pads are still the ones that came with the wheels.

Cheers. I've not had any squeal to be fair, apart from first 5km of first ride before I toed them in.

Will try widening the calipers a bit.

Found a review earlier that said "you’ll go through the first set of pads like toilet paper after a dodgy curry, but the harshness of the rim surface finish starts to wear down and then the pad wear rate declines"

So hopefully it will start to calm down a bit. Going to the pyrenees with 2 sets of spare pads so hopefully they will not both be needed.

Sorry but that info is total boll@cks. Classic internet made up tosh.

Deffo look at how you have those blocks set up on your bike because that is very unnatural wear. If set up correctly this pad/rim combo is no different to any other alu wheel (apart from the superior stopping power) and should last just as long.

Struggling to see how the blocks are the issue. The last pads on my alu rims have been on all year and done nearly 14,000km so far.

With Exalith pads they are in same position, fractionally toed in as per Mavic's diagram.

There's a lot of reports online of mad wear for first 500-1000km, sure it will get better.

Which stems from lazy journalists copying each other then spilling into forums. File under 'All Look pedals creak'.

there's 7 people in this thread who have had the same pad wear issue on new rims.

Just a thought - I had R-Sys and thye flexed a fair bit. I like to set my brakes close to the rim so ended up rubbing the brakes under any sort of load, such as sprinting/climbing out of the saddle. I have noticed brake rub on friends wheels too. Can this be the case here?

Rubbing without intent?

people use their brakes differently and in dif situations, the Mavic Cosmic exalith wheels we ve got have done maybe 3000km, pads not even 1/2 worn. i believe that the much cheaper BXP pads are the same as the exalith ones.

So 7 days and 20,000m of descending In pretty poor Pyrenean weather with ONE set of pads.

Issues seem to be over, and braking is noticeably better than standard alu rims.

What's the rim wear? I'd happily trade pad wear for better rim life.

I have a set of SLR R SYS and the front appears to flex under high downhill cornering forces.... Not even necessarily on the brakes.

The front just seems really imprecise and vague in fast downhill corners. For want of a better word it just feels whippy. Eliminated the idea that it might be the front end of the bike itself by running other wheels which track fine. I had one incident about a week ago whereby it felt as if the tyre had deflated mid corner, so alarming was the understeer.

To get an alarming amount of understeer I think it is more likely you shifting your CofG and tensing up, so you probably felt something you didn't like and did everything wrong in that moment, if you did dab your brakes as well then there you go. Just get the wheel checked out anyway, there will be something wrong with it or there won't.

Well no, because it wasn't just the one occasion and also it doesn't happen with my other wheeler in place, as mentioned in my previous post.

Here's the other bit again that you skipped...

OK, so now I'm being cyber stalked by some numpty who didn't like the fact that I pointed out how he was talking total twaddle in a totally unrelated thread.... Oh dear.... :roll:

Just to resurrect this thread - I have a set of the 125th Anniversary wheels, and am very happy with them.

I'm contemplating purchasing a second pair of clinchers, but this time the Mavic Cosmic Pro Carbon Exalith ones - 45 or 50mm rim.

My concern would seem to be groundless, which was about the braking surface detiorating\coming off on the steep descents, and when I eventually make it to the Alps or Pyrenees.

I'm assuming everyone is still happy with their wheels performance, and the braking surfaces are still intact?

A few years ago, I read in a few places that people had seen the braking surface start to come off, and then this process accelerated rapidly, but nothing in recent years, so perhaps that was a bad batch, and or something they have improved on since.
If I do go for it, I think they are either 2017 or 2018 models.

Thanks

No rim will last forever....

In fairness your a total tool . Here’s another thread where a different front wheel wasn’t working right for you. I suspect you just don’t know how to ride a bike properly.
Superstar complements thread “I bought a set of their Pave28 in the sale for £140. For the money I can't fault them, they're pretty light and strong. They seem to be extremely robust and i have clocked up some serious miles on them, over roads that are not always the smoothest in the world. I must admit to finding the 20 spoke front a little vague on fast descents though.

He has not logged on since October, so I doubt he will ever see your post.

Probably doing “serious miles”. Or has wiped out as a result of losing his front wheel because the frame had front wheel steering.

Dan - Mavic haven't changed the Swissstop brake pads and treatment since 2013. They're still using Exalith 2 which was improved to reduce wear. Only the rim shapes have changed.

Thanks for that, hence the 2 definition I guess, and if it's ok after 5 years of production, I guess they must be pretty happy with it.
