How many of these fg/single speed stories start with: So i've got this old frame with horizontal dropouts...
and I do, (10speed american 70's steel roadbike) and modernizing it would be pointless (not to mention cost wayy more than its probably worth) so I thought I'd give single-speed and fixed gear a try.
I doubt my legs are quite ready for the joys of fixed gear (but it just looks soo fun) so I jury-rigged the bike to single speed: (read, tore off the derailleurs and shortened the chain to fit the best available gear ratio/chainline) in my case, 52/20 (27" wheels and 165 crank...I used Sheldon Brown's gain ratio system and I think this works out to something sane)
I took off for my morning commute (mostly rolling hills, maybe 2 500m flats on the whole 6.5 mile trip)
I was expecting to huff and puff my way up the hills, maybe walk one of them, and proably be late to work.
Instead I somehow made it 2 minutes ahead of my usual time and managed to make it up the hills a bit easier than I usually do.
my one error: didn't tighten the rear axle well enough (and/or my chainline sucks) and had some rather odd chain derailment going on (the chain got stuck between the 52t chainwheel and this ornamental protector plate, while on the rear it just jumped down 2 sprockets. did I mention even with having to flip the bike, and fix this, I somehow made it to work earlier than usual?
I think I'm going fixxie as soon as I can get some wheels with the right hubs ordered (if my rims weren't almost shot I'd think of rebuilding them)
