ConsThis one is black - I prefer silver but I am not complaining
ProsGreat price for such a durable and important item
Old-fashioned article at what is to me as a 70 year old codger an old-fashioned price (and please note SJS long may it remain so!).

Looking for a dished alternative to this
22 Nov 2018
I am using this sprocket with an Alfine 11 and a CT-S510 chain tensioner, and they don't align very well - the chain falls off every now and then. Can you recommend a dished 18T sprocket that will fit Alfine 11 and straighten my chain line?

Secondary question - I just bought a pair of Ortlieb Back Roller Pro Classic QL2.1 Panniers from you guys via Ebay, is it possible to combine them with an order from website to save on shipping?

Thank you.
As this sprocket is dished and not flat, we would need to see the bike in person to advise further.

Unfortunately Web orders and Ebay orders can not be combined.

Can you sell the plastic chain guide that fits with this?
