large cassette= chunky shifting?
i was thinking of switching from a 12/25 105 9spd to a 11-32 or 11-34 type cassette while running a single 42 up front on a long cage 105 derailleur and 105 brifter
will this give me some nasty shifts? i don't mind a slight difference but i don't want to switch if this is going to be cumbersome or slow
