Hey all,

Just got a set of the Ksyrium Pro UST Disc wheels and used them for the first time on Saturday. It's been 16 years since I had a new set of wheels. My question concerns the rear hub and cassette. After every ride, I clean my chain and take off my rear wheel to floss the cassette. While flossing, the cassette popped off the rear hub as one unit. It looks like it was designed that way to make maintenance easier (ie get to the bearings etc)....but I wanted to check with you guys, Is this a normal? Do wheels made now days have this? I pushed the cassette (as a unit) back on and it seems to lock in place and is held together by the thru axle when mounted on the bike.

Thanks
