We've always been kind of peeved at Campagnolo and Shimano for not making front derailleur adapters that match the aesthetics of their front derailleurs. We might have to take Shimano off that list, as their new Dura-Ace 7970 front derailleur adapter finally does something right. It looks pretty good. Not incredible, but it is a huge step in the right direction after their older clamp, which always looked to us like a Sora holdover. The big change is anodizing. The dark anodization trounces the murky matte finish of the older clamps, even though it's probably the same clamp underneath. Thankfully, this design works not only with Dura-Ace electronic and mechanical, but it also works with all Shimano braze-on style front derailleurs. Which means it probably works with all Campagnolo and SRAM front derailleurs as well. The Shimano Dura-Ace 7970 front derailleur adapter comes in two sizes -- 31. 8mm or 34. 9mm in diameter.
