In my previous question we determined that I probably need new chainrings. I was/am planning on replacing the chainrings, and leaving the original crank.
Now this bike is running Shimano 105 FC-5600 kit. I refer to the Shimano drive-train compatibility chart here which says that that the FD-5600 front derailleur needs FC-5600,FC-5650,FC-R600 or FC-R550 front cranks.
Since I have to replace it, I wouldn't mind upgrading to a Ultegra-level chain-ring. According to (my reading of the chart), this is not possible. (which seems strange, I would have thought any 130BCD chainring with the same screw type should work. Is there a problem with derailleur clearance or something?)
1) Is this correct?
2) If so, is there a compatibility chart with other brands? (FSA/SRAM - obviously Campy wouldn't work!)
Thanks in advance
