Different styles of QR skewers

[Arjimlad]

My son's Carrera Subway has been dismantled by feckless older teenagers who lost the QR cam nuts off his skewers.

I've replaced the skewers with some off an old road wheelset but the design is different.

I don't know if it's important to get the correct skewers with the concave nut which sits under the cam outside the forks, or whether the road-style QRs are adequate?

I think this is MTB style..

This is road style..

These are my son's without the nuts.

Thanks for any advice

The enclosed style are supposed to be better than the exposed cam. Less prone to clagging up and coming undone. That said, I'd never had any problems with the open type.

Also with dirt getting in and causing wear on the cam. Both Campagnolo and Shimano use the enclosed type for that reason.

Thanks chaps, so it's not critical that he has open cams.

No, so long as they're in good order and are tightened properly.

Road style enclosed cam QRs grip a fair bit better, as do allen key skewers.

For rim brakes and the rear wheel grip doesn't matter that much, but the reaction force from a front disc applied hard can lever the front wheel out if the QR doesn't grip well enough (seen it happen, fortunately without injury, but at the cost of bent forks).

MTB tyle open cam QRs are generally cheaper & easier to make for small manufacturers, and lighter.

Thanks - that's the bike sorted - now to work out an anti-bullying strategy for the older teenagers who thought it funny to take the wheels off his (new to him) bike.
