|Campy Racing Triple/Shimano Der & Chain?||Chen2|
Dec 27, 2001 1:36 PM
|Thinking about trying this on my wife's bike. She has an Ultegra triple, the 52 and 42 chain rings are too big. My question is, can I replace the Ultegra crank set and bottom bracket with the Campagnolo Racing T crank set with 50-40-30 chain rings? Will the Ultegra shifter, front derailleur, and chain work well with the Campy crank set? All nine speed parts. This would give her a much more useful set of gear ratios. Campy does offer that crank set.

|I am shocked at how many people do exactly the same things to their bikes. Several times recently on this board and mtbr.com I have seen questions about things that I have just done. And here is one more.
Yes, it works just fine. I have not noticed any problems at all. I had to adjust the front shifter cable tension and the stops, and I think that I may need to lower the whole shifter to get the cage to be in an analogous position. That is pretty minor. I like the Racing T unit. Make sure you get the right BB spindle length. I think you can get the crank from Cambria and maybe ColoradoCyclist for 89 dollars. Not too shabby. I think Nashbar has the BB on sale.

|This is really good news! I'm really glad to hear that you have experience with this conversion. The 50-40-30 crank set will give my wife the ratios she needs. It would be simple to replace the Ultegra triple with the new Dura-Ace triple but it comes with 53-39-30 rings and the rings are specific, I don't know if the 53 can be replaced with an aftermarket ring without sacrificing shifting performance, and she surely does not need a 53T ring. I think we'll give the Racing T a try, maybe change the shifters, derailleurs, and cassette to Dura-Ace, if the Campy crank works well on her bike.

|Why don't you just buy the 40T and 50T chainrings for the Ultegra Triple crankset, and save yourself some $$.
Even if Shimano does not make the right rings, some third party manufacturer must (such as TA or something like that). 5 minutes on the web should yield positive results given the wonder websites such as google, Branford Bike, Excel, etc.

|Check out this page on Branford's site for Engagement (Salsa) chainrings for the 130mm bolt pattern found on your Ultegra triple

|Thanks for researching my problem but we've already tried after market rings on the Ultegra triple but the shifting performance really sucked. At the Branfordbike web site Ultegra triple page there is a little note that says "other" rings should not be mixed with the Ultegra triple rings, and based on my experience I would agree with that. The middle ring is ramped especially for helping the chain up from the 30 to the 42, that is the tricky shift on the triple. All of the aftermarket rings seem to be designed for doubles. But thanks again for your help.
