This is now all 'finished' as a single speed in the sense that it rides somewhat normally.
The tensioner (bought from velosolo along with the conversion kit) on the chain moves if I hit a bump, so much so that the chain either goes really slack or starts to rub against the bit that keeps the chain from flying off. I've tightened it up but it still does it every few hundred metres. Maybe a dodgy tensioner? Should I just get rid entirely and shorten the chain more?
Need to remove the gear cables and buy some bullhorns or use my spare handlebars and get some normal brakes as I have the bullhorn brakes and some more tape ready.
Any ideas how I go about making this completely fixed? Can I purchase a track wheel that would work with the spacing on my road bike or can I make my freehub fixed somehow?
