A couple of months ago, I bought a Trek 3700 to replace the ancient Ross 10 speed that a friend gave me, as I'd started commuting to work by bicycle. I'm a very tall guy, and the Trek 3700 was about the least expensive bike that came in a 22.5" frame, especially when I managed to get last year's model for a real bargain. Let me just say that I love it. Love it!

But now, even though I've insisted to my older relatives that they don't need to spend money on my birthday, I have some birthday money to spend and I'd like to start moving the bike towards being "the perfect bike" instead of just "my awesome bike." My commute is under 4 miles round trip, I seem to do a 10ish mile ride at least once a week and I'm working my way up to longer rides, but I'd also like to be able to use the bike for more of my errands.

So here's what I'd like to buy:

Fenders
Rack
something to attach to rack
cycle computer for when my phone crashes while tracking
lights? (still considering building a fancy light kit)

It appears that these fenders will fit my bike, though none of the LBS around here seem to carry them: http://www.amazon.com/Planet-Bike-Fr...7747661&sr=1-1

but I'm up in the air a bit about other choices. Do the extra posts that some racks have matter? Are wire baskets that fold up a better choice than bags? Is there a cycle computer that doesn't cost an arm and a leg but does display good info? Is this the wrong section of the forums? Hopefully
