Shimano Deore SGS RD-M591 Rear Derailleur SILVER

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.

      We've got two bikes with versions of this derailer. Mine is the low normal. My wife's is high normal. Both shift 11-34, 9-speed in back, one SRAM and one Shimano. Mine has 48,36,24 in front. That is 47T capcity, 2 more than advertised, but it works fine! Both setups shift smoothly and reliably, using DiaCompe/Rivendell friction shifters. No problems.
