Capacity is a simple concept. Any time you shift to a chainring or cog other than the largest ones, the derailleur cage needs to take up that much chain, so if you have a 22-44 crankset you need a capacity of 22 and for a 11-34 cassette you need a capacity of 23 which would require a total capacity of 45.
Derailleurs don't care how many speeds you have all indexing is done at the shifter, as long as the model number matches the datasheet you can ignore the speed spec and concentrate on the other specs.
good explaining.
his link to his bike seems to indicate that it uses a "7 speed cassette", funny that it would use 7 and not 8 speed stuff as the bike cant be that old, but if thats what it is, then thats what it is....
Ive seen 7 speed cassettes on sale at a store here in Montreal at reasonable prices, so they are around.
