Please note,11/13/15t sprocket wheel of m9000 was useable for m9001 as well,choose the one need by pic above.

We find people use 11/13/15t in daily cycling which cause these cogs were most vulnerable,we suggest our rider replace these cogs in 3000km for keeping their performance at the best

Since there are 10pcs of the cogs and one SPEC tag packaged in a single Shimano retail bag, please understand that it is impossible to ship each cog within the retail bag unless you order 10pcs of the cogs at the same time.

Package Include:

-1pcs Sprocket wheel only
