I have a Shimano FC-R600 compact crankset from 2004, now with worn-out 50T chainring. (At this point I'd prefer to by a new bike, but hard times and all...) I've found an online retailer with these two chainrings:

105 FC-5750S (silver, 10S 50T/110)
105 FC-5650 (10S 50T/110)

Any idea which one is the proper one for my crankset?

(Small ring has no visible wear, and I already have a new chain and cassette waiting to install. Thanks.)

The 5750 and the 5650 are both 10-speed chainrings with the 5750 being slightly modified and part of the 5700 group. In practical use, there will be no functional difference. Buy which ever is cheaper.
