I'm currently running a 7-speed freewheel and 700x35 wheels. I have gotten hold of a pair of 700x23 wheels with a 6-speed freewheel attached. Can I swap one out for the other? If so, can I easily add QR to the wheels?

Thanks.

Quick Release is something that cannot be added-either it uses it or it doesn't. You can certainly swap out the wheels, but you must also swap out the freewheels. Hope this helps..

Thanks for that. Can I just confirm that the 7-speed freewheel won't fit on the 6-speed hub? Also, if I use the 6-speed, will there be any chain issues?

Thanks.

If they're both freewheels and the most common BSC threading, then you can swap one for the other. The only issue is if your 6 speed wheel was an Ultra 6 spaced freewheel (made for 5 speed hubs), then your axle length might be a little short and you'll end up with a slight wheel re-dishing issue. But 95% of the time this should work. And no chain issues in any case between any 6,7 speed setup
