Mavic Cosmic UST - anyone?

[DS240]

Looking at wheel upgrade and trying to balance cost/weight/quality.

So far the Mavic Cosmic Pro Carbon SL UST has caught my eye. Seems to tick all the boxes in being aero but fairly lightweight and far cheaper than Zipp, Enve etc.

Is anyone using this new wheel and have any feedback on the Tyre/rim set up?

Reviews seem positive but real life usage feedback is always better. Cheers.

I'd looked at these too. While I haven't yet bought any Cycling Weekly seemed to like them http://www.cyclingweekly.com/editors-choice/mavic-...

What are you looking for in this "upgrade"? Go faster, better ride 'feel', more bling ?

[DS240]

My new bike has come on some fairly cheap rims. Whilst they do a decent job at the moment and would default to winter wheels later, the one obvious area for an upgrade in addition to training is the wheels.

Looking for weight upgrade, aero benefits and simply better/faster quality than I have now.

They’ll also be a feel good factor getting back to racing in the spring/summer.

I can tailor training rides to include some hills, but they are generally short and I’m unlikely be heading up mountains any time soon so don’t need all out climbing wheels.

I don’t want wheels with huge rim depth but a nice all rounder.

£1560, blimey.

Unless you're racing at the very pointiest end of the field, that seems a big chunk of change.

Those Selcoff carbon clinchers from PX looked good value at £599:

56mm deep, U-profile, tubeless compatible.

I can get them for £1,100 which makes the purchase a little less painful.

Compared to fairly comparable wheels I think they look quite ‘good value’.

I have a pair of the 2014 vintage. Make sure you go for the alloy brake rimmed version. Also the mavic tyres are utter ste The carbon brake rim wont inspire much confidence going down a hill at high speed. A colleague of mine, who is giving away 20kg in weight killed a rear in a year over 3000km due to his weight (LBS says). He had them covered under the warranty. The bearings are not so good on the hub rear-i replaced mine under warranty. otherwise they are pretty true provided you dont cane them over rough roads. They are fine. I would probably recommend them. My wife has Fulcrum racing quattros which roll nicely too with an alloy insert and without a weight penalty and equally good looking so maybe have a look at those also. Id recommend them actually over the mavic's and that having run the mavics for over 3 years.

They're nothing more than stickered up Chinese imports, with a decent mark up too, so they don't offer great value either.

Thanks, some points to think about.

What I have read seemed to imply the braking was pretty solid in wet and dry on these new ones.

Lifespan is something I’ll have to research more.

The new Cosmics are quite different to older ones like yours, a new wider rim profile, laser etched carbon brake track offer better ride quality, aero benefits and braking.

Rim life should be good, carbon specific pads tend to be softer than alloy ones to give better bite whilst reducing wear to the brake track.

There was a guy on here with some 20k miles on a pair of carbon Enve 65s, my 2014 Zipp 303s are barely worn and I've ridden them wet or dry.

Yeah, but UK seller so:

- no import duty
- some guarantee/customer service (although I realize PX aren't the best)
- faster postage
- the newest rim shape technology (ish!)

Pros and cons....

They’re looking better value today at 20% off - £480!

Think I’m going to go for it.

Watched a video on Mavic which covered the new UST wheels and it gave me confidence. Not found anything negative but they are still fairly new design at the moment.

Found some 3T Orbis II C35 LTD Stealth under a grand which is tempting, but I like the tubeless tech idea of the mavics and general specs.

I have Cosmic UST Disk and although due to work and bad weather haven’t had much chance to ride they seem to have transformed the bike and are a lovely wheel.

To be fair I know f-all about bikes so take my review almost as seriously as ‘how to make friends and influence people’ by Katie Price

Where abouts are you OP?

I only ask as a cycle shop I follow on FB have just advertised that they have the new Cosmic UST available to rent out, could be an option to try before you buy?

Performance Cycles just outside Cirencester.

Cheers for the suggestion, but in Jersey so too difficult. I’d heard mavic dealers do a test ride scheme but no dealers on the island.

Anyway, I’ve just taken the plunge. On balance I think they offer up a lot for the price (though not exactly cheap, but compared to other brands).

Time will tell but hopefully I’ll feel the difference. They’ll definitely be saved for summer best though. Bike should look good also!

[DS240]

Done... very happy!

Going wait for better weather before swapping over to the carbon pads and keeping these on for summer.

Lovely

And regardless of the fact mine don’t improve my cycling I think they look
