Yesterday, I rode my bike for the first time in months (30km commute one way), and on the way home, my chain dropped off, and I tried to pedal forward to pull it back on, but ended up twisting it pretty badly. I found a shop half way home that replaced the chain in about 15 minutes, so that was good.
The unfortunate part was that I planning on changing derailleur and cassette (28t to 32t), so now I have a chain that is cut too short. Now, I'm looking to order thew new parts, but need some advice on what I'll need to lengthen the chain. Will I need a multiple connector pins/master links? Any good advice to go about doing it? It will also be my first time change a derailleur so a little nervous about that too.
