What's the exact cable pull and indexing of

  • Shimano Alfine SG-S700
  • SRAM G8/9
  • Shimano ROAD RD-5800
  • SRAM Force Rear dérailleur
  • other...

The idea is to use ST-RS505 brifter with an IGH. Not entirely impossible as it seems.

  • The blog article that you reference is specific to external, derailleur gears. IGHs are engineered to use specific pull ratios that correspond only with IGH shifters.

  • @JonR The title is explicitly asking for specific values. Not opinions. There is another fact sheet suggesting otherwise. I haven't had the time to integrate the details, yet.

Whatever you may read this CAN'T work properly simply because the gaps between each of the shifts are different on the Shimano Alfine SG-S700, there are THREE different gaps. The only shifters not made by Shimano to operate this hub properly are:

Jtek 11 Speed Bar End Shifter


11 Speed Microshift Inter11 STI Levers
