I’m running an Alfine 8 with a narrow-wide front ring on the middle position of a triple crankset.

Its a full susser so have been running a jury-rigged rear mech as a tensioner.

Bought the Alfine CT-S500 tensioner (the two jockey wheel version) only to find that it does not align with the cog when you are running the Alfine cog ‘dish out’ to match the chainline of the front chainring.

It comes with 5mm of spacers to correct but it gets no where near the correct position…it is only engaged into the derailleur hanger about 3 turns when it lines up.

I flipped the cog but the chainline is very poor, I can swap a spacer on the BB to bring the chainring in a couple of mm but its still way off.

Has anyone got any weird or wonderful ideas to space the tensioner out? Its a real shame as its much more compact than a normal mech and stronger spring as well.

I ran a superstar components zinger tensioner on my full suspension / alfine setup without problems. Not overly helpful right now but perhaps an alternative for you

Thanks, I did see the Zinger but £25 v £7.50 for the Alfine version was an easy choice.

I’m selling my FS frame so may sell my Zinger too

But not if it doesnt work!

Correct bigyinn. Didn’t think about the fact it may not be adjustable!

podge, let me know if/when it happens, thanks

I’ll probably have time to hunt it out this eve
