Road STI with MTB Derailleurs Not that this question hasn't been asked to death but I'm experiencing very poor shifting, here's my setup:


Shifters: ST-5700 (10-Speed Road)
Derailleur: M6000-SGS (10-Speed MTN)
Cassette: Sunrace CSMX3 11-42T (10-Speed MTN)
Adapter: Wolftooth Tanpan Inline 10-Speed (Mounted on cockpit)


My issues are shifting up into the middle ranges 18 - 24t, it's not very precise and I need to click the lever a little over. Then there's shifting down into the 11t which it struggles at times. Is there a way to solve this? I've tried mounting the tanpan on the derailleur, adjusting the barrel adjusters for better indexing but the shifting is never crisp and precise.
Shifters: ST-5700 (10-Speed Road) and Derailleur: M6000-SGS (10-Speed MTN) will not work - the pull ratio is different.  You need a 9-speed Shimano MTB derailleur.  A 9-speed derailleur works directly with older Shimano 10-speed shifters, and shifting will be "normal".  (IIRC, some of the newer 10-speed, sub-105-level shifters use a different pull ratio.)
