How do quick release wheels work?

What kind of chair are you using? I recently had to swap out my 24" spinergy spox wheels with kenda tires again and put on a wider, knobbier set of tires when I made a trip to the east coast. Make sure the tires you want will fit on your current rim.

If you already have the right hubs and the quick release axles (the needed length will vary depending on your wheels) for your chair, then I don't see why not. If the rugged tires are considerably wider than the everyday set you're using now, you'll probably need to get extra spacers to increase the rear wheel spacing. The spacers can be found at your local hardware store.

Also, if you're changing the size of your rear wheels from larger to smaller or vice versa, make sure that you know how to adjust your overall chair set-up accordingly.

Re: cheapest place to buy wheels. I've had good luck with ebay before. It really depends on what kind of rear wheels you're looking for. Sportaid.com has a good selection, but they are not the cheapest. You could take a look to get an idea of what you need, though.

EDITED to add: Again, using quick release axles on the new 26" knobbies should not be a problem.

It's basically a push button mechanism that enables you to put in or pull out your rear wheels quickly and easily. Make sure your axles, axle sleeve, and hub will all fit properly with the chair you'll be using. Get spacers if necessary.

hi, ive had a few QR wheels on my chairs over the years. now i have an otto bock... QR, with solid tyres ( makes powersliding easier)

the QR mechanism is just a different hub spindle which bolts to the chair, so ought to be able to be adapted quite easily by anyone with a spanner and an allen key.

if youre in the UK, contact social services and see what they can do for you.

and you cant use any old wheel... coz the hubs are different, and having a hub/wheel respoked is damn expensive... my chair has carbon fibre wheels... which weigh ounces, NOT pounds.
