I just bought a new Cannondale Synapse Carbon Disc SE 105 and I am having trouble with the chain dropping on gear 50-11.
If I shift on the front chain ring to the biggest ring (50t) and in the rear to the smallest one (11t), the chain drops to the outside of the chain ring under load after a while. If I rotate the crank manually without load I can see that the the chain is jumping up on the chainring teeth.
It seems like the front chain ring should be 2-3mm further outboard because the gear teeth catch the chain plates causing the chain to jump.
Does anybody have the same problem? Any tips how to solve it? It is not a problem with the high/low limits on the derailleur.
