    U.S.E. QR system

    Anyone know how well these work compared to a traditional cam QR?

    They get tight in half a turn. Supposedly tighter than a standard cam QR. MY friend has them but i didn't really play around with them

    Thanks for the feedback. I bought a set of Ti one's and hope they work great.

    This type of "external cam" qr skewers can't generate nearly the clamping force of the internal cam types made by Shimano and Campy. They work ok if you have vertical rear dropouts but can't be relied on if you have horizontal dropouts as the rear wheel is likely to shift under load.

    This is not an external cam QR, it is a newly engineered type.
    Here is the link to USE's site which, unfortunately, doesn't really shed a lot of light on how these things work .

    Well I have vertical dropouts so I don't think it will be an issue. I just wonder how well they tighten and remain locked in.

    You're right, I can't tell what the clamping mechanism really is. They say it tightens in "a half turn", which is what an internal cam skewer does too.

    Just received mine............yes, they tighten by rotating the wing nut (that being the lever end) til it contacts the drops. Then you turn another 1/2 to 3/4 turn and they are on there. Seems different and can't wait to see how they work on the road. I hope they work as good as they claim.
