Yes, Alfine/Nexus hubs need specific indexed shifters, regular indexed deraillieur shifters won't work. An in-line adjuster should work if there's not an adjustment mechanism in the J-Tek shifter. BTW, Alfine 8 and Nexus 8 use the same shifters, the Alfine trigger or Nexus gripshift work equally well in either hub.
