Shimano 8 internal help
 
Just joined and will be looking around.

I have a bike I am trying to bring back to life. It has the shimano nexus internal hub 8. I was wondering if there is a different shiftier option I can use other than the grip mounted rotating sifter that it came with.
Thanks

Why, look what a simple Google search brought up! https://www.treefortbikes.com/cat/15...l-Hub-Shifters

The OP asked about Nexus hub but the link was for an Alfine shifter. I am pretty sure there is no difference but we should be sure. My understanding is that the Nexus 8 and Alfine 8 have internal differences but the external shifting is the same.

i just spent all afternoon servicing my Nexus 8 which is maybe why I am interested. And BTW after four years it was fine. I think going forward I will use the Sturmey Archer schedule. I mean do nothing until it totally rusts out. 😀

The rotating "grip-shifter" can be replaced with a "trigger-shift" with the same number of speeds (Shimano, of course). I did this on one of my folding bikes that had a grip-shift which was hard to shift wearing heavy gloves (it's my "winter" bike). The hub is a Nexus 8-speed, and the trigger-shifter is Alfine. I just went out to my garage and checked... the Nexus hub is "low-normal", and the display shows the correct gear. I have another bike with an Alfine 11-speed hub. This is a "high-normal" hub, and the Alfine gear display is reversed compared to the one on the other bike.
Bottom line: if you get a trigger-shifter that's Alfine vs Nexus, the worst thing that's likely to happen is that the gear indicator will read backwards. There may be a way to reverse it... I don't know.
