[QUOTE=nun;14841360]Anything with more that 28t will be a MTB cassette.....but it doesn't matter, as long as you use the appropriate derailleur MTB cassettes work fine on your road bike.[/Qwork]

I measured the cage and its definitely a long cage.

My lbs bought the left over inventory from a shop that went under. My volpe was part of that Inventory, but had been stripped of some of the parts. They must have put whatever cassette they had available. Not sure about the chain. I need a new chain anyways, so not too worried about making the existing one work.
