Hi,

I would like to try out the Osymetric chainrings and I've been doing a bit of research and it appears one of the things that is key to the front mech working well with these chainrings is to have 'shims / spacers' on the front mech and to have chain catcher. All the info I have found relates to having a braze on front mech.

I have an Ultegra Di2 band on front mech. Is there a spacer / shim / chain catcher solution out there that is suitable band front mechs?

Thanks.

    I run Rotor Q Rings 52/36 / Rotor 3D cranks on my Giant with Ultegra Di2 without any problems. Had to move the mech up a little to account for the rings but that was all. No chain catcher.

    Ditto but with 9070. Personally I always run a chain catcher but I've yet to have a dropped chain on the q-rings. You just take the oval into account when positioning the height of the mech and job done.
