So opportunity knocked; a guy at work (we have many avid cyclists/commuters) happened to be parting out a frame that cracked. It had a full rsx group in good shape. Paid $100 for the set, which included brifters, fder, rder, 7 speed 11-24 cassette, crankset, bracket, chain, brake calipers and cables. I can't use the cassette with my current hubs, so I'll probably sell that on and pick up 7sp freewheel to put on my rear hub. The cables are old and probably stretched, so no value there.

The rsx crank is one of those newfangled 36/46 compact cranksets. Do you think it mate better with a 13t or 14t freewheel? Or should I search out an 11t? And I believe that since I'll be buying a new freewheel, it's best to also replace the chain, yeah?
