SRAM v Shimano
I presently have Shimano Ultegra 6600 groupset with a 12-27 rear cassette which I really like. Shimano have stopped making this casssette.
Will the SRAM cassette 12 - 27 be compatible with my present set up? Is this SRAMs 'equivalent' to ultegra range.
(I don't much want to change to the new Shimano 6700 range 11- 28 casette - too wide - and there is some doubt re compatibility anyway I believe)
