I have no issues with dropped chains so far. I've had the set up for two weeks now and have been on about 10 rides with no problem. I'm using a shimano dura ace 11 speed chain and the configuration seems to be very quiet.
Just a quick update on the longer Garbaruk cage. I think I'm just going to go back to the original SRAM long cage instead... I just can't get the Garbaruk extended cage and jockey wheels to work properly. Sorry for hijacking the thread, but a quick question for @Cody
please: do you have any issues with dropped chains? I get everything shifting well, but downhill in a high gear (where there is less tension on the chain) I have issues. It's almost like the clutch / spring is not quite strong enough. I can't shorten the chain because I need it for the 46. Thanks.
