I've bust the inner plate on my DA and it is a flimsy bit of plastic aka carbon crap and is £119 from Madison. I'd rather have a proper bit of metal down there and the Ultegra one looks like it could do the job.

Is it possible to remove the rear cage on a broken DA 7900 and put on a cage of an Ultegra 6700 mech? The gap between jockey wheels is identical but neither have a grub screw or any obvious way to get the cage off the body. LBS knows nothing. Any ideas?

    Google shimano docs, should get you the address of the shimano technical support web site. They have exploded diagrams of most components which should help you work out how to take them appart.

    yes they can be removed, they unscrew from the spring... there is a stop/grub screw (No 7 in the tec docs) that needs removing first.

    Helpful docs and advice - thanks. I've taken a cage from an Ultegra 6700 short cage rear mech and it bolted straight up to the Di2. Now I have a proper metal cage rather than the carbon flexi cage. It feels as crisp and slick as I could wish and maybe more so than when the Di2 was undamaged. I saved a lot of dosh. Weight gain was +5g.
