What’s the difference between Dura Ace 7800 and 7800?

Upshifts still require a lengthy 20-degree arc (or 40mm of linear throw, 30mm of which is nothing but slop) and single downshifts an even longer 27 degrees or so. In contrast, Dura-Ace 7800 requires a 20-degree throw for both upshifts and single downshifts, so if anything, downshift throw on 7900 has gotten longer.

Can a Shimano 7900 be used with a 7800 derailleur?

Shimano say the revised cable pull ratios on 7900 essentially make backwards-compatibility with 7800 brake callipers and front derailleurs a no-no. Sadly, we’ll have to mostly agree. Mixing brake components yields either a too-firm lever with reduced power (7900 levers with 7800 callipers) or a somewhat spongy lever with grabby response.

Which is better a 7800 or a 7900?

7900’s braking performance is definitely superior to 7800 with a snappier and more fluid lever feel plus noticeable improvements in power and modulation. Many readers have lamented the revised cable pull ratio on 7900 – thus sullying the idea of mixing groups – but if that is what was required to get this level of performance, so be it.
