I have been riding on this new wheel set for the past month or so and could not be happer. For the price these are totally worth it. I am fairly new to cycling and purchased an entry level road bike that did not have a great wheels so the Cosmics were a noticeable upgrade to weight and speed not to mention look. The tubeless system is really great I ride on tarmac and hard limestone around 20 to 40 miles at a time and wanted more peace of mind around avoiding a flat.
Awesome wheels and tires at a great price. They arrived setup and ready to go, I just needed to add the sealant.
Bought these as a first try at tubeless, hoping to get fewer puncutres that need fixing by the roadside this winter, fingers crossed. So far I'm impressed, the set up was easy and the wheels were true out of the box and still true 300km later. They arent the lightest set and the combination of wheel and tyre feels slightly less lively than my fulcrum racing 5's and GP4000's.
I'm 23 y.o and I did half pro races with these wheels..I can say really nice wheels to race on and of course training. Thank you Merlin for cheap price!
After a 100km of riding I'm very happy with these wheels. Ran true and felt solid straight out the box, not sure about any Aero gains but super easy to set up on my 10 speed with the spacer provided. I've swapped out the Mavic tyres for some Gatorskins I had spare, just because it's the middle of winter here and punctures are plentiful. I plan to try the tubeless Mavic tyres in the spring. Overall great value upgrade on my Commuter bike that should last for years. Recommended.
Great wheels and tyres for the price. Standard Mavic quality and they roll well. The UST system has been faultless so far and I can definitely feel the difference in rolling resistance from my previous set up that came with the bike.
Very nice wheelset, acceleration is there and they feel solid
First ride disaster... got a 4mm puncture on the rear wheel and sprayed silicone all over my bike (just outside the 3mm specs of what Mavic says will seal ) had to install a tube to continue, meaning had to clean all the silicon out from tyre and rim...grrrr Had my doubts about tubeless to begin with and this has just reaffirmed them. I'll be going back to gatorskins tyres and doing away with tubeless forever. On the wheel side of things cant fault them, smooth, sturdy, good looking wheel should do me for another 5 years like the last set did. The new supplied Mavic UST tyres seemed a little slow, hopefully the gatorskins will speed things up. Although max rim pressure only says 100 psi which might annoy some that prefer a higher pressure Still highly recommend even with the tubeless debacle . Great value for money
