Drivetrain Replacement Advice
I am in the process of overhauling my Ultegra 6600 drivetrain thanks to a worn chain and 6650 50T compact outer ring. I have managed to source a 50T 6650 Silver chainring after a LOT of looking around, and I have a new 6600 chain. However I wanted to replace the cassette too, but it looks like the Ultegra 6600 12-27T is discontinued. So I think my best option will be a 105 5700 12-27T. Will the chain I have purchased be ok with the cassette from the new group? And will there be any issues of having a 6650 chainset, paired with a 5700 cassette and a 6600 chain? I will prob replace the 34T chainring too to be on the safe side.
I have never had to do any repairs of this nature so does anyone have any advice for me and know all the tools required? I have the tool for the plastic crank cap, the one for removing bottom brackets and of course numerous allen keys. Do I need anything else? Is it worth replacing the bolts used in the chainset? What specific lube is needed after a routine clean and refit of chainset?
I am very tempted by the Ultegra 6700/105 5700 11-28T cassettes but I hear that shifting performance with 6600 RD and shifters is hit and miss as it is not supposed to support a cassette of that size. And I can not justify forking out for a 6700 RD on top of all this.

Yes the 105 will be perfectly fine...
For the procedure, look on the park tool website, there's plenty of tutorials.
Shimano bolts can be reused, oil is the only lube you need... tolls: cassette lockring removal tool, a chain whip, a large adjustable spanner... for the chain a chain splitter if you sue the connecting pin, nothing if you use a quick linkleft the forum March 20230 -
Thanks for the find... Some 6600 parts are starting to get scarce0

I cannot find a Silver 34T 6650 chainring anywhere. I have seen Ice Grey ones or R700's but not what I am looking for. Anyone have a line on where I could get one?0

Is the R700 identical to the 6650 34T? They look very similar.

Shimano part number you want is Y-1HO 34000 so looks like the same part yes
