You may have to lower the FD. Other than that you shuold be good to go.tduncan said:I'm looking for some more low gears. If I change to a FSA compact crank will I have problems with chain jump using my DA FD. I currently have a FSA Team 53/39 DA FD and DA RD w/12/25 cassette. Any other set up suggestions? Thanks
Don't worry a bit about the short cage 7800. It works just fine with the 12/27. I've run it thousands of miles on both the '04 & '05 versions.tduncan said:Thanks for the feedback. Glad to hear that the compact will work up front. My LBS is concerned that the 12/27 cassette will not work well with the DA RD 7800 short cage which is the model I have, hence the 12/25 cassette I have now. I'm trying to keep the cost down if that is ever possible.
I agree. I have a 12/ 27 on my DA 9-speed (RD-7700) and a 12/27 on my DA 10-speed (RD-7800). Both work fine. But IME, in both systems when running the 27, it will rub slightly against the guide pulley, even though the "B" tension screw is all the way in. It hasn't seemed to affect shifting performance or accelerated wear in any way, however.yellowspox said:Don't worry a bit about the short cage 7800. It works just fine with the 12/27.
