ok, this is a better description of the System, together with a dimensioned drawing: http://www.bikeradar.com/road/news/arti ... ims-50212/
There is someone from Mavic replying in the comments section of the Bike Radar article and he provides the definitive answer on whether one must use only Mavic tubeless tyres with these wheels.
The short answer is "no". You can use any UST tubeless tyre with the Mavic wheels.
The long answer is that while you can use another company's UST tubeless tyre, Mavic is guaranteeing certain tolerances with their tyres and thus the quality of the interface between tyre and rim on their "system". That's why they are able to say that their tyres can mount X percent easier, etc.
- The wheels/rims meet the UST standard.
- You are not restricted to using only Mavic tyres with the wheels, but Mavic does make guarantees about the quality of interface and ease of mounting when using their tyres.
- You can use any UST tubeless tyre with them (though you may find some more or less easy to mount than others). Mounting results may vary.
Were I to purchase a disc frameset these would actually be my theoretical ideal as I would love a carbon wheelset that I could use tubeless without rim tape. Corima made a tubeless version in the past, but I don't know if they do anymore. Other than that there's just the Easton Aero 55's to my knowledge, and now the Mavics. I'd feel comfortable riding carbon tubeless since I wouldn't have to worry about braketrack delamination. I would be far more hesitant to do so with the rim brake version.
Now we wait for actual ride reviews.
