Seems like every hobby I take up, results in an endless stream of parts purchases, whether they're really needed or not. I think I might be a hoarder.

Lately:
SunTour XC rear derailleur for the '88 Bianchi, so I can run a triple
Reach-Around fender brackets from River City Cycles (I'm looking to add fenders to my road bikes, but I don't want to run skinnier tires in order to accomplish that)
spare Panaracer Pasela 700x28s

P.S. Oh, and I bought a chain, some new tires/tubes, and a shifter cable for my girlfriend's project bike.
