I have a chain and the rear brake to cable up up and I'm good to go. Original brakes are back on unless I can figure out how to fit the Kona ones. Weight has started to creep up :? a BB I was going to use has been shelved as it appears to need a special fitting tool, rear cog and spacers are cobbled together from an old cassette just now, I reckon I will tidy this up too. Sooo sitting at 17.4lbs just now with chain, grips, rear brake cable and possibly a tensioner. And looking at it I don't think its cost over £150.
