My 2005 commencal Supreme 6.1 has 9mm skewers with Commencal Quick Releases. Unfortunately they have a habit of coming undone when the riding gets particularly bumpy! I've tried to source 9mm hope skewers on Wiggle/ CRC/ Evans with no luck. My LBS is also struggling to get the parts from Hope (is 9mm that unusual?). Any ideas on somewhere I can get hold of a set of decent 9mm skewers?

Cheers....

you could do better than looking at hope for decent skewars for a start ... they are one of the worse skewars in the world today

as for 9mms ... giant make a particurlar good one but it might be a problem getting it not on a bike

i thought 9mm was the standard nut i could be wrong if so would only use shimano or these: http://www.salsacycles.com/images/zoom_flipOff.jpg
which are what i'm currently using

Thanks both for your help. Apologies for being thick, but what is the measurement for the length of the skewers? I thought it was from the inside edge of the QR to the end of the Skewer (in my case 135mm front and 170mm rear), but a very helpful CRC rep said it should be 'locknut to locknut'? Does this mean the inside measurement from the QR to the bolt on the other end of the skewer?

Cheers....

Locknut-to-locknut is the dimension for the hub width, not the skewer length. Skewer lengths are either "front" or "rear" ;-)

What's the hub? Is it some sort of integrated axle/skewer arrangement? 9mm is a very odd size for a skewer.

Hi Mike. Got it! If I just measure the hub width then thats the magic number. Presumable the rear is awkward, as you need to ignore the cassette....

My front Hub is a Commencal one that came with the bike with a 9mm skewer. The rear one is a Hope Pro 2 hub, and the skewer is 10mm.

Thanks again for your help.

janek, the 9mm is the axle, i think you'll find the qr is 5mm in diameter

Presumable the rear is awkward, as you need to ignore the cassette....

Nope, the rear is locknut-to-locknut too - the locknut is outboard of the cassette otherwise the cassette would hit the dropout :-) 135mm is the standard rear hub. As Mike says, 9 and 10mm are the standard F and R _axle_ diameters. Conventional QRs are 5mm shafts. Anything should fit, just get a Shimano Deore one.
