Replacing chainrings on my Ultegra 6600 triple crankset
Hey y'all, I am new to this forum and to the world of chainrings.
I have an older Shimano Ultegra 6600 triple crankset (on a 10 speed) and I am wanting to replace each of the chainrings individually. I would like to get the exact same sizes and specifications if possible.
They are:
* 52t, 130mm BCD, "SG-X 52-D"
* 39t, 130mm BCD, "39-D"
* 30t, 74mm BCD, "SG-X 30-D"
I have done quite a bit of searching but I don't know enough about cranksets to be certain about what I'm finding. Does anyone know where I might find these? It does not have to be Shimano brand, just something quality that will work. Links to products would be very helpful, or advice on where to look, or alternatives are also much appreciated.
Thanks

Would initially look at just replacing the complete crank with NOS (if you can find one) as the cost of replacing 3 rings esp the outer may be more than the cost of the complete crank.
For brands, Shimano, Stronglight, Specialites T.A, Middleburn & Sugino are all options, takes you choice on price, spec (ramps) and availability in your area

Are they all in need of replacement? It's very unlikely the 52T is worn out unless you used a worn out chain for way too long.
I'm not sure if the original rings are available new anymore. You might have to hunt on ebay or other places.

Yup, that was my experience a couple of years ago in trying to replace the middle ring. I settled for an FC-6600 (rather than 6603) for a double rather than triple. It doesn't have the ramps the 6603 has but it shifts from granny to middle just fine, albeit maybe not quite as smoothly. A search on ebay at that time found "slightly used" 6603s for sale. Riiiighttttt.....
