Used the Alfine 8 speed with cables a few years ago in the winter but found it far too clumsy in use the shifts would often find ghost gears in between shifts and it always felt like it was wasting power input from me and being slow as mud I haven't got much power in the first place.
I now have a new headache in the form of sram XX on my sons race bike, it insists on dropping the chain at every opportunity or dropping the chain between the lower jockey wheel and the cage!!!
might stick the alfine on his new bike and see if he notices.
Cheers, Tel.

Replace the derailleur pulleys with CNC aluminum non-floating pulleys to improve shifting performance on SRAM X drivetrains. The gears are so closely spaced nowadays, and the shifters are so precise, that floating pulleys are no longer useful. Once you've fixed that, you can tighten the derailleur's range of motion so the chain doesn't fall off the sides of the cassette anymore.
