Rear cassette change

edited June 2016 in Workshop
Hi all I work away a lot with my job and I try to take my bike with me all the time,so after reaching the ripe old age of 56 and finding myself in Scotland (very hilly) on some of the hills I was nearly grinding to a halt so I came to the conclusion to change the rear cassette.
I have on the front a triple 52/42/30 and on the rear a 11 x 26 my game plan fit a 11 x 32 on the rear an increase of 6 teeth,so how many links longer should my chain be and should I fit a new rear derailleur long one, the current one is a medium one? Thanks for your replys.
I really want to get up them hills.

    I think this depends on the exact model of the rear mech. They generally say what max sprocket they'll cope with and what their total capacity is (max-min chainrings)+(max-min sprocket)

    Your total capacity is (52-30)+(32-11) = 43

    You might need to fit an MTB rear mech to cope with that...
