Catamount dual-suspension; it's been a singlespeed since I first built it up, but when I heard Sheldon Brown had died it finally gave me the kick I needed to fix it.
Details: Catamount frame, olde bomber z4 forks, avid sd7 levers/brakes, xtr crank/chainring, surly cog, purple kmc chain, parts box for the rest.
Gearing: 32:18, firstly because I am a huge wuss and my commute home has a big hill to get up, and secondly because studded tires/4" of snow on the ground right now makes me want all the extra help I can get.
