This is an image of my 1984 (?) Raleigh Technium TriLite. I recall purchasing it on 1984 as a road bike, but I found on Copernic (metasearch engine) that the Scott Tinley TriLite was introduced in 1988 ;-(

Anyway, this bike has been converted to a single-speed commuter. And remains my favorite bike!
As an SS enthusiast, I think you would ride at another level if you converted your Technium TriLite to single-speed! Go to the Fixie/SS Forum and get some savvy advice!
