thanks, its a road bike with skinny tires. appreciate your advice. think i should stick with 26 and not try the weird sizes. 23 * 700 is quite rare here. 700 * 45, I can forget about getting a tube from the local shops.

the usual sizes here are
28 1/2 roadster
26 mtb
26 1 3/8
24 mtb

I am looking for a more relaxed ride and there might not even be clearance for 45c. I think I better give up that idea.


Would like to share the way I discourage theft on an old commuter bike, a bit drastic and the lock is easily opened.
the heavy U lock I sometimes use over here. Look at the diameter compared to the AA size batt and incase it gets stolen, check out the department store bikes.
