2006 Specialized Langster

I bought this bike 2nd hand off our favorite online classifieds.. I rode it for a bit freewheel, then got an 18 tooth cog for the fixed side; now wishing I had gotten the 17 so I'd have more flatspots. I now ride it fixed exclusively..

I removed the rear brakes to give it a try; I'm going to put the rear brake back on as I don't always ride with my SPDs on, and with such steep gearing I can't lock the rear w/o them!
