Hello Folks I know it's rude to ask a load of questions as you join a forum, but I'm head scratching on my Ariel Arrow race bike build :shock: I've got a Arrow in pretty good nick, it's been turned into a cafe racer in the past, and i'm building it to race with British Historic and maybe some roads....
