Tel":1zslv6wb said:Shimano 600 Ultegra and Shimano 1050 had very low stack height. Should be able to source one reasonably easy. Modern alternative that would be fine but getting hard to find now would be a Tange Passage. Other than that it'll have to be a Chris King.
Hilary Stone has an unused Tange Passage listed on his site at £12 + postage
