I have a set of DT swiss Mtb rims model XC1800 and every time i go for a ride the rear wheel after a while becomes "loose" the only way in which i can explain is (the q-release skewers are still tight) if you move it from side to side it feels like a bikes whos hubs are loose or busy packing up. but there is nothing wrong with the sealed bearings. i have however noted that the hollow axle diameter is not the same it is bigger than other hollow axles but the q-relesase skewer is still the standard size. So i am pretty sure it is the wrong skewers i need "thicker" ones do DT swiss rims have non standard q-relesase skewers ?
