Di2 Climbing Shifter Hack

Inspired by a hack on Chris Froome’s 2017 TdF bike, I took apart a Di2 Remote Climbing Shifter (SW-R600), removed the bulky plastic buttons and housing, added two smaller buttons using two metal nuts, and used some heat shrink to keep everything tidy and hopefully keep water out! I can now change gear whilst on the tops without having to have the unsightly original part cable tied to my bars!
