I am considering getting a pair of the 52mm Cosmic Carbone wheels, but quick question to those they have them or have had them, what length valve is the most suitable?
I'm taking a guess that 60mm will be a bit short and 80mm far to long? Or is standard length valves together with valve extenders an option?

Hi Al
You will just get away with 60mm valves

Cheers Craig, quick response!! Plus, a double bonus is that I have just looked and I have two brand new Conti Supersonic tubes with 60mm valves in my garage already.....

60mm are fine Al but I currently have 45mm in mine & I just carry valve extenders should I get a flat.

Yep 60mm conti tubes are fine. The valve hole can be fairly large and the valve stem rattle a bit, so I always used the threaded 'nut' that comes on most tubes to clamp it down a touch, just to stop the noise.

Wheels arrived, and 60mm Supersonic tubes fitted but I cannot get my track pump onto the valve as there isnt enough of the valve protruding. My Lezyne frame pump fits the valve okay, but I have no idea how much pressure is in the tube?

I don't know about the mavic carbon 50mm wheels but I use 60mm conti supersonic tubes with my Shimano 50mm wheels, there's about 12mm of the threaded part of presta valve sticking out beyond rim - I use threaded connector on Lezyne track pump which works no problem.

My track pump is a Specialized one and to be fair the pump head is quite large, which is clearly the problem -
HERE I wonder if you can get some sort of adaptor that screws on like the Lezyne does but has Presta style at the other end that would push into a track pump head?

I don't know about that cobmi Alan (sounds a bit like a simple valve extender) but I know you can get a screw on brass adaptor for attaching a pump head with a lock on Schraeder fitting to a threaded presta valve if that helps. I've got one if that's any good & you want to try it. Much cheaper than forking out for a new track pump.
