I have been wanting to throw on a Sugino XD2 triple on my Cross Check to give me the ability to do touring. The problem is while my shifters work with triple they don't have a trim feature and i would need to replace my rear derailleur and buy a new chain.

When you add all of that up....super compact would make a heck of a lot of sense Not to mention i could run a smaller cassette for my usual commuting and throw on something larger when i go on a loaded tour once or twice a year.
