Currently have an Ultegra 9spd standard 39-53 front 12-25 rear.
Can I TEMPORARILY (one ride) run an 11x32 cassette on that derailleur if I don't use the 32? (disregard chain length as the only time I would be in the 28 is when on the small front)
OR for added safety from accidentally shifting into the 32, could I swap out one of the sprockets from a different mfr (ie Sram Shimano) with another?
(I could add a sprocket from my Ultegra cassette onto the SRAM 11-32, then remove the 32 and be left with 28 being the largest gear)
IE: REMOVE the 32 SRAM in the 11,12,14,16,18,21,24,28,32 ADD a Shimano 15 sprocket and make it a
Concerned if there is a ramp issue between mfr's for 9speed cassettes.
