I had been looking out for a new bike/frame for Sam to use for school.
I was lucky enough to pick up a 1992 Kona Lava Dome (thanks Jim), in an 18 inch frame with various additional accessories.
Sam and I decided to single speed it, to keep it simple and also to keep it cheap (I don't have any more gear shifters, or rear mech's in the spares box).
I went for the classic 32:16 or 2:1 ratio. That's 32 teeth on the front chainring and 16 teeth on the rear.
I bought a Dead Head Single Speed Kit from the Woolly Hat Shop - a bargain at £9-99.
This kit converts your existing 7/8/9 Speed hub to single speed. It includes two rings - 16 tooth and 18 tooth plus all spacers required to sit on your rear hub.
Sam also managed to strip the thread out of one of the crank arms (it served me ok for four years), so I also ended up buying the cheapest Shimano crankset I could find.
I removed the large and small ring and reversed the middle ring to ensure that I could tighten the crankset bolts sufficiently.

This was before I got hold of a singlespeed sprocket converter and a chain tensioner.
The (almost) finished article
no chain tensioner
with added riser bars and Avid levers fitted
new shimano crank set
Dead Head single speed kit fitted
