I have a 2011 Dolce Triple. I replaced the stock 13-26 cassette with a Shimano MegaRange 11-34 cassette, and the stock 30t small chainring with a 24t. This gives me mtb gearing that has allowed me to make it up every hill without having to do the "walk of shame".

The problem is the chain drops I get when I shift from the 42t middle ring to the 24t. It drives me nuts! I adjusted the chain catcher so it's parallel with the teeth in the small chainring, so it's probably the huge difference in chainring sizes between the 24t and the 42t.

Here's a picture of it from last weekend's ride.
