I am looking to replace the 21-23-25 triple Ti cogs. I put together an 11-25 cassette using a DA 11-23 by dropping the 14 and using my 21-23-25 from my Ultegra which has 5,000+ miles on it. I want to have the new setup for all 9 gears. Does anyone know where online I can order those upper 3 cogs from? I don't want to just buy a 12-25 cassette.
For those wondering why I did this, I plan on eventually using the 11-23, but for now still need the 25 for some hills. I also wanted the 11 for those times that I want just a bit more than the 12. :-)
