I have a Giant Boulder 520 (1996) and I am upgrading it bit by bit.
I bought a new Shimano 7 speed cassette 11-28T. Now, I want to replace my crank set, however I do not know which size to buy.
Does it have to have the same number of teeth as my current one or does it not matter? I currently have a 42/32/24 crank set, do I have to replace it with a 42/32/24 crank set to avoid having to replace the derailleur or anything else?
I am currently thinking of getting a Shimano crank set FCTY501 42/34/24 compatible with 6/7/8 speed. Will it work with my new cassette and will I need to adjust my derailleur?
