I've read a few threads on this topic but I'm still confused. When do you need a long cage? My bike came with long cage and it's SRAM Apex compact 50/34 with 11-32 cassette. I've read that you only need long cage with triples but do I need long cage for my set up or could I go short if I upgrade down the road?
Someone was also telling me that short cage provides better shifting and reliability. Is that necessarily true?
