Razors Edge ★ Posted April 9, 2018 Author Share #2 Posted April 9, 2018 The question is when Shimano (in active MTB Dev) and SRAM (they have it in prod MTB) answer and if it fits existing bike frames and wheelsets (the guy claims it is as simple as swapping the cassette).

Razors Edge ★ Posted April 9, 2018 Author Share #3 Posted April 9, 2018 And, to my mind, the Di2 upgrade for Shimano would seemingly simply be a new rear derailleur and probably not even a new front derailleur. The shifters themselves shouldn't matter since just sending a signal. Tom Link to comment Share on other sites More sharing options...
