DT Swiss 350 freehub movement

**sethschmautz** · 05-21-2018, 08:32 AM

I replaced my cassette last night and noticed a slight but if play in the cassette. I removed the cassette and the freehub exhibits the same motion/sound. Anybody know if this is normal or should I be concerned?

With the cassette attached, if I reach my fingers around the large cog and pull the cassette away from the hub I get a small movement and "thunk". I get the same movement and "thunk" when I push it back in toward the hub with my thumb.

Movement is imperceptible except for the noise. I tried tapping the end cap back in gently with a hammer, but I don't think it does anything.

Thanks in advance.

Guessing the free hub slid out a few mm when you pulled the old cassette. Just push down on the cassette/freehub to get it back on all the way. Regardless, tightening your axle bolt will do the same.
It’s designed to do that for “tool free maintenance”.

Pretty much what he said.

does it happen with the wheel in the frame of the bike and the axle done up?

Uggh. Of course. No, it doesn't happen with the QR tightened. In my mind I was thinking the tool-free maintenance design was the culprit, but totally overlooked the simplistic answer that this is tightened with the QR. Thanks all.
