[quote="steamer1227":186mic1u]But I would like to know before I buy any shifters or derailluers if I can add some more cogs in the rear since it’s only a 3×5 set up now.
A 9 speed cassette won’t fit on the hub of your current 5 speed wheel. In order to go from 5 speed to 8/9 speed you would need a new wheel, rear derailleur, cassette, and shifter. It’s not worth it.[/quote:186mic1u]
