Afternoon fellow twitchers.
I'll cut straight to the main point of the problem.
If I am in the big ring and move my way up the cassette, by one of the top 2 gears it will pull my chain off the big ring and 9/10 end up jamming between the small ring and the frame.
Initially we found the Rotor Inpower 3D+ crankset isn't exactly a match made in heaven with the TTE as the frame sits slightly proud of the BB which means as the cranks turn they slightly rub on the frame itself. We had to shim out the cranks 3.2mm to get the perfect fit without any rub.
I first notice the chain issue when I was riding along a slight incline of road and after slowly notching back through the gears as the road went on it suddenly pulled the chain off and was jammed against the frame. (I'm beyond worrying about the damage to the frame by now as its already taken all the paintwork off.)
After getting the bike on the turbo and doing some investigating it seems to be as you switch through the gears the front derailleur auto adjusts a tiny amount, but as you get towards the top of the cassette it is too much and pulls the chain off. We managed to adjust the Di2 settings all the way outboard in hope it would stop the auto adjust and just keep the chain on, that was not the case.
The chain still comes off when in the big ring/large gear ratio, which i know isn't a gear i should be riding but it shouldn't pull the chain straight off without warning. I've fitted a chain catcher but whenever it pulls the chain off it just moves the catcher out of the way and falls between the gap still!
I've seen multiple professional mechanics and different bike shops and no one has either seen this problem before or managed to fix it. I can't be the only person running a TTE/Rotor crankset combination?! I'm hoping someone has had this exact problem before and can lead me in the right direction. I've had the bike since January and it would be nice to get it sorted haha!
I had contemplated the idea of getting a different power meter and going back to like a standard ultegra crankset but I haven't really got the extra money to be chopping and changing cranksets/pedals and whatnot.
Cheers,
Oliver.
