Re:
Hi I've got a Merlin model, I'm building some wheels for it and trying to keep it as original as I can except I'm putting on golden arrow gears as they look like they could have been original, just checked the BB and its 70x130mm, the cups are bit pitted so if I can will replace with a modern type, think you should keep the saddle till you find better the charge doesn't look right but the are very comfortable cheers
