thanks
weight is not the main issue, but it is one of the issues
i am working on a slim and fast clockwork that i want to bring under 9 kg's
sadly it's not gong to be 100% retro but i am trying my best
i googled the ritchey wcs shifters and found nothing, but what you are saying sounds very good.
running currently on 44/32 only so it might work without changing the chainrings
cheers
A
