Currently running Ultegra R8000 11 speed Di2, typically with an 11-32 cassette. As I’m getting fitter I’m seeking out more climbs on my local routes, but I need all the help I can get since I still have weight to lose.
My bike came with an 11-34 cassette and I never really liked the spacing…the 11-32 was better but there were times I wished for another gear. I know some folks have had varying degrees of success with a SRAM 11-36 or even XT 11-40 cassette but I’m not sure I want to chance it since they’re out of spec for the 11 speed derailleur.
It’s time to replace chainrings…then I saw some places have a new 11 speed crankset for not much more than the rings (and mine is all scratched)…and then I saw a bunch of places have deals on 12 speed components. I can do the work myself and sell current parts…so I could probably do a Shimano 12 speed group (Ultegra shifters/crank and 105 derailleurs) for net $800ish. This would allow me to run a 11-36 cassette which is basically my current 11-32 + an extra climbing gear
I get this sounds like I’m lookng for justification to buy upgrades so I can ride up grades
I’m wondering if anyone has used the Shimano 12 speed 105 11-36 cassette…does it shift smoothly or is it clunky to deal with the bigger cogs? I think it must have a longer cage since it’s rater for 34 or 36, not 30 or 34 like the Ultegra (from what I’ve seen).
12 speed Di2 is advertised as having faster/smoother shifting…have you found that to be the case or is it comparable to the last gen?
