Hi,
My wife wanted to ditch the single ring and install a double and bash on her new unridden Giant Trance SX, so I ordered up what looked to be the correct front derailleur to use with a 3x10 crankset with the big ring removed and her old XT shifters (3x10 direct mount M781).
Today when finishing off installing a dropper on her bike I noticed that the cage of the front derailler, even when installed at the very top position on the direct mount, fouls the chainstay when the rear shock is compressed.
Does anyone know if... I ordered the wrong derailleur? (It certainly looks like I did). I notice the regular Trance which shares the the same frame has an SLX derailleur installed...does this have a smaller/shallower cage?
I'm hoping the fact that it's an XS frame has nothing to do with it.
Ok, in the hope that somebody may have experienced this and have a suggestion...
...this morning I went out and bought a Shimano m786 2x10 front derailleur, which has a smaller cage and is "optimized" for tire and frame clearance. Well regardless of where I position it on the direct mount the trailing edge of the cage still scrapes along the chainstay when the suspension is compressed.
So, can anyone point me in the direction of where I can find out exactly what front derailleur a 2014 Giant Trance size xs is originally specced with?
I'm starting to think this is an issue with running a 3x10 crankset perhaps...is the granny ring too far inboard towards the frame? However it looks like I might have the same issue even if the derailleur was set up for the slightly further out granny ring on a 2x10.
I can try and get some photos posted if it helps.
