Thats what i was thinking very 70's lol i've never seen a fixed gear with a springer before so i guess your right! Roland is a one of a kind hehe
Got the springer all done and dusted looks no different but it works ;D
Aiming to have my wheel laced up by tuesday and solder a switch into my rear light tomorrow, fingers crossed nothing nasty pops up!
Slowly very slowly :'( the springer self destructed and i still havent build the front wheel >_<'
However he does have a new hair cut (bars,headbadge, front mudguard)
