Phistowrote a review of Mavic Ksyrium Elite UST Wheel on October 27, 2019
Familiarity: I've used it several times
I love the wheel design, the low rolling resistance and the hub. It's a nice step up from my stock wheels that are on my Bianchi cross bike which I use as a commuter bike. Been riding on it for a couple months and finally got my first puncture. Sadly, the sealant didn't take. I refilled the wheel and tried again, but no go. The puncture itself is tiny and I'm frankly surprised that after all the hype and positive reviews I've read that this system was not as advertised. I called Mavic and they basically shrugged their shoulders. I have a request in to Competitive Cyclist to see if they have any suggestions as well.
My next step will be to remove the wheel, check for debris and maybe insert a tire plug. Which frankly is a lot of work for what was supposed to be a great new tire/wheel system for a commuter bike. I ride in NYC and this sounded like a great idea. A self-sealing tire! Well, perhaps I can save this barely used tire and not have to shell out another $70 for a replacement.
Update: While I’m still determined to try to fix this, Competitive Cyclist was nice enough to send a replacement. Great customer service as always.
