Singlespeed & Fixed Gear "I still feel that variable gears are only for people over forty-five. Isn't it better to triumph by the strength of your muscles than by the artifice of a derailer? We are getting soft...As for me, give me a fixed gear!"-- Henri Desgrange (31 January 1865 - 16 August 1940)

Yes size matters. You would need a tube that fits inside and can fill up all that space. Most tubes have sizes that you can use them for listed on the box or something and from experience a tube for a 23mm would work for a 25mm tire. Just get a "road" tube and make sure it is 700c and not 650c.

Better companies generally make tubes that are a little lighter. Unless you are racing professionally, it does not matter at all. Wal-mart tubes would work just fine.

EDIT: I basically meant don't get a 26" mtb tube.

Not really,"normal" tubes are expected to fit 22s or 23s,it's a given...25s is NOT a stretch at all. 28s are a cut-off point.
