ah i never tire of gear talk, especially after a fast ride home from a den of iniquity.
spin, spin and spin some more.
nowt wrong with the low gears especially for normal pace city riding, I liked 62-63 inches (like yours) a lot, but enjoyed 67ish a bit more once i got used to it>> if you are tempted just put 42 tooth on the front. I could never get on with the city standard of 71" (42-16), and had to defend my gear choice at times against both other messengers and knarled commuters alike.
if you are more comfortable with your legs at a blur stick with it.
