QR / quick release / skewers


I've just found a crack on my QR from Roval wheels (probably I was using too much force), and I need ones (or at least one), S-Works Tarmac SL6 frame.

Can you feel the difference between 'standard' ones that weights >100g and light ones? (35-50g?) I'm not talking about the weight but clamping force (and bike handling later etc.)

Or difference between ones with internal cam mechanism and the ones with 'external' (of course I'll avoid ones with plasticky parts).

somehow wheel manufacturers, even with most expensive wheels and lightest wheels, provide quite standard skewers weighting (roval, shimano etc.)
