I've finally managed to source most of the parts for this now (so expect some movement on this post).
Just need some period flat pedals and a straddle cable yoke (I've got some Onza Chill Pills but they're too new).
I've also have had to draw up some new decals for Gil to make as he only had some for a Pro.Flex; this has taken ages, what with his accident and all.
Anyway... I need some suggestions as to what to do with the elastomers in the Flexstem. I took up B77's suggestion on getting some long board bushes but I can only fit one. http://www.retrobike.co.uk/forum/viewtopic.php?f=3&t=246099
As you can see there were two elastomers but I need something to replace the black rebound one. Looking at pictures of the Girvin Flexstems the design seems to have changed for this Offroad one. I guess I could try and cut the elastomer down but is there anything else that would make a good substitute?
