I'm using the Ultegra 6800 on my road bike (with 46/36 chain rings), and the 105 11 speed on my GG - also with 46/36 chainrings. Both the Ultegra and the 105 shift well- fast and clean shifts- but despite tinkering (both are clamp style) I still get a lot of chain rub issues. I suspect that the cages are designed for larger chainrings, and don't function as well with the 46/36 up front. I want to order the BURD for my road bike, but the clamp diameter wont work on it's narrower seat tube. I did order a Shimano 5700 10 speed cx derailleur for my road bike and will test it next week. If it works well, I'll likely order the BURD for my Haanjo which has a larger seat tube.

Thanks for the info. Haven't even opened the box for Shimano CX 5700 yet. Surprising how little time I have with 2 grandchildren running around the house!
