I went out and shifted my derailer all the way in, and it's clearing my spokes by about 1/8-1/16", so I think I should be good to go.

Also set up my lights and computer. Like a dummy, I left the double stick tape off of my computer mount and I'm out of zip ties (Dammit ). I've set up plenty of computers before and never forgotten that. Oh well, shouldn't flop around or anything.

Phoebeisis, I do have a seat bag with some spares in it (tube, pump, tire levers, patches, allen set, and usually zip ties ). I also have a chain cleaner with some degreaser and lube.

Now if it warms up at all, I can try commuting.

Thanks again everybody.
