Unless your tandem is very very old you should have some sort of cross-support tube in the middle of it going from the top of the head tube, normally, to the bottom of the stoker's seat tube. like this one: http://www.flickr.com/photos/skvidal/2673426270/ but it'd easiest to ask a framebuilder, I suspect. Bilenky, bob brown cycles both build tandems. -sv -- You received this message because you are subscribed to the Google Groups "RBW Owners Bunch" group.
