Perfect replacement, easy installation
Fit perfect with my nexus 8 hub. Needed to replace original assembly after I damaged the cable clamp, not a separate part, like an idiot in a hurry to fix it the first time, always plenty of time to fix it the second time.

This shifter works great.
Received this shifter in like one day. Just as pictured. Mounted easily and adjusted the cable easily, then away i go.

Not too exciting, but
It’s exactly what I needed when I switched to a frame with different dropouts.

Alfine 8 uses several different models of cassette joint.
This cassette joint recommended to purchase with my Alfine 8 SG-S7001-8 was the wrong model for my Alfine 8. This one has wider notches and does not lock into place. had to purchase the Cj-S7000 separately, but will use the other parts that came with this kit. I recommend checking compatibility before purchasing,

If you need it, it's the thing you need.
I bought this to install a shimano alfine 8 internal gear hub and it works great. It had the appropriate washers for my drops, and it is nice insurance to have the small plastic bits around in case of a mishap.
