Hey everyone-

I have an 06 Langster which I just got fixed this weekend. I went with a 17T cog (Surly) because that's what my freewheel was (never changed from stock). Anyway, fixie is wonderful, and the freewheel is coming off, but I am (already) considering a smaller cog. The fixie setup seems to carry a lot more momentum up hills, and is obviously a little trickier going down them. More speed in the flat areas never hurt either. I found a nice Soma 16T on a certain website that looks like it will go for cheap and ends around 5pm (my time). My question is, am I likely to notice a significant difference, or would I be better off getting a 15? I don't need a huge jump (I actually am not strong enough for a bigggg step), but I would like a little bit steeper gearing.

Thanks.
