The original specification describes a wide-link design and light-action shifting. Confirm compatibility with your shifters, cassette, chainset and derailleur hanger before ordering; a 9-speed cassette alone does not establish compatibility.
The capacity, sprocket limits and product weight above are carried over from the existing listing and have not been independently verified against this item's model markings or manufacturer specifications.
