I'm thinking of upgrading from a 9 speed (11-34T cassette) to 10 speed. Scoped out a few components and 1) Shimano Deore XT CS-M771 10-Speed Cassette 11-36T 10-speed HG cassette 2) Shimano Dyna-Sys, super-narrow 10-speed HG chains (hg95) 3) Shimano Ultegra 6700 Shifter (for 10 speed)
I have an existing Deore XT rear long cage derailleur used to support 9 spped 11-34T cassette. Two part question:
A) can existing rear derailleur support HyperGlide chain and cassette? B) any other comments on compatibility of proposed new components or suggestions?
