Hi, So a while ago I bought a 41 DX frame, fenders and springer off an eBay seller, believing it was all compatible. Turns out the frame headtube is a fraction under 5 1/2". Whereas the springer steerer tube is 6 3/8". What to do? What should the steerer length be? I'm guessing it's at least 1/2" too short? Any suggestions and advice would be brilliant.
