Here's my first singlespeed bike Done on the cheap with a lot of bits I've taken off my other bikes.

Circa '98 Ridgeback aluminum frame.
XT Cranks from ebay
XT Levers swap-outs from the LBS
Surly Singulator from ebay
Chainrings and cogs from ebay
Wheels from my MTB that's getting converted to disc brakes
Bontrager bar that I swapped for a flat bar on my hybrid
Stem from my wife's old GT MTB
Etc. etc..

Currently riding 32x16 with the intention of slowly increasing that as I develop some hill climbing legs




Think I'm about 1mm off a perfect chainline:


Cheers,
Ian
