Use this as your B tension screw on Deore rear derailleur, enabling use of 11 (or 12t)-36t 10 speed cassette!
Works with wide-range 10 speed cassettes and STI shifters! This is our favorite derailleur for road bikes with a touring cassette. This will handle 32t to 36t* low gears and it still looks like a traditional derailleur - not a Transformer. *With 36t large cog, you might need a longer B tension screw (see related items) to keep the derailleur cage away from the large cog.
