Has anyone been riding with a Shimano e-type front derailleur on their carbon Mojo? My thought was installing one would help eliminate any damage to the frame in the event of chain de-railment. My concerns were 1) will it fit and 2) will it be stiff enough during upshifts as there is no re-inforcement post on the Mojo like frames made for the e-type derailleurs.

One option would be to find an older version 9-speed e-type (M952E) as they used to have a carbon fiber plate as opposed to the newer aluminum version (they were lighter too).

Any e-type experience out there?

Greetings from Ibis!
The E-type FD is sort of a band aid you would use if you (as a frame designer) can't figure out any other way to mount a FD on your bike.
Regarding chain damage, I wouldn't worry about that so much since the lower link and hardware (and FD) are in the first line of defense down there.

Cheers!

Hans, thanks. Tom told me to e-mail you regarding this issue, so I'm glad you caught it on the forum. I didn't feel too strongly either way, so you convinced me to stick with the standard bottom-swing design.

As for the rear XTR derailleur, I increased the spring tension on the main upper pivot to help reduce frame contact in the bumpy stuff. I did this by disassembling the upper pivot and drilling a new hole about 45 degrees past the stock spring hole. Kind of a compromise between a SRAM derailleur with no forward movement and the stock Shimano.
