Hi Daemon, its an 1999 Steel KHS Crest frame V brake only it was Electroplated by Daft Vader before I bought it looks awesome in the sunlight, now to find a decent tensioner.

The only thing madder than the SSWC is the Single Speeder Cyclo Cross World Champs in Portland (SSCXWC):

Since building my SS I discovered a few things, wich forced me to make some changes. Running your chain without any form of a tensioner on a vertical dropout frame does not work, no matter how you do it, the chain will bliksem off. Using a normal 9sp chain is not adviseable. I run a 32 - 14 ratio and I broke 2 chains in 2 days. A tensioner that pushes down on the chain is not ideal, especially if you ride hard, or on very bumpy terrain..the chain will bliksem off and you will hit your nuts on your handlebars. So since I made the following changes everything seems fine...touch wood.

 

Thicker chain, shorter BB and Tensioner that pushes up on the chain.

You should try not to use a rear cog smaller than 16T because 14T cog cause more tension per chainlink as there are less links on the cog at the same time than would be on a 16T. 

 

Try a 36 in front and a 16 at the back.  It's a little bit easier than 32/14 but it's less strain on your drive train.  I run 36/16T on my 29er on flatter rides and I also used that ratio at karoo2coast, for cross country and races with steep climbs I go for 32/18T on 29er.

Unfortunately I don't own a single speed, but I once worked on designing one for use in rural communities. The design objective was to allocate more of the cost to a better frame, forks, cartridge style BB and sealed hub bearings, and save by not having some cheap junky shimano SIS 18sp system on the bike. Unfortunately never finished it completely (as you see no brakes could pose some issues), but here's the general idea. Single speed (32/16T).triple clamp rigid forks (so that they can be repaired by just replacing the tubing with standard off the mill stuff). Unisex frame. Yeah... it was my first attempt, so a lot of improvement to come.
