But I Dont Understand Why There Not Allowed Because They Basiclly Got The Same Geomotry As The Old TAP
I've no idea why they aren't allowed, but probably because they are a replica of an old school bike rather than being a proper old school bike.
Personally, I can barely tell the difference between the originals and the replicas (then again, I was never a Raleigh buff).
But the organisers have to draw the line somewhere I suppose cos it would be quite easy to make a new school bike with a 1" headset and no brake lugs just to fit into OS rules (I've had people asking me whether it would be possible to make a dialled bikes frame like that, but I just tell them I think it would be against the spirit of the OS Series).
