Rim size vs inner tube size.

[Benny]

Hi. This is probably very much a noob question, so apologies in advance For some reason my quest shipped with 3/4" rims (20-559). I've got some 25-559 inner tubes left over from previous bikes (new, still in box) and was wondering if it was possible to use these on my 20-559 rims.

Cheers,
Simon

Tire/Rim Width Compatibility

Sheldon's compatibility chart is here:

Quest serves a dual purpose role; part quick tourer/part commuter. The rim width was chosen to suit tires in the 1" to 1.5" width range, biased toward narrower tires.

The Quest 1.0 accepts only 1" wide and narrower tires, due to the fork crown design. The Quest 2.0 accepts up to 1.3" with fender clearance, or 1.5" without fenders that cross the fork crown (SKS Raceblades don't cross the fork crown, for instance).

Cheers,

Doug
