• Hi guys,

    I bought a Vitus 979 and took it to my local bike shop to get it put together as it was shipped from Spain. However, the mechanic cracked the rear derailleur dropout as he was screwing it in and now i'm not too sure how best to proceed.

    Does anyone know if the part is easily replaceable? Or do you think I should find a frame repairer who can have a go at fixing it? It's made of aluminium which I understand is not as straightforward as Steel to work with.

    Or alternatively I just convert it to a single speed...

    What would you guys do? Any help / advice would be appreciated. I'm a bit of a novice so apologies if i've skipped out any details.

    I've attached some pictures of the break. Cheers!

  • This is a really funny coincidence, I just had an identical frame (except in blue) with exactly the same issue come into the shop i work at.

    In the end i cut off the old hanger completely as it was totally mangled,then i used one of these


    It worked fine, pushed the limits of the rear mech limit screws a touch, but was all good

  • pushed the limits of the rear mech limit screws a touch

    I ordered one of these problem solvers for another project. It says when fitted you may lose your last one (or two) sprockets due to the RD being offset. The offset should be 6mm (the thickness of the added hanger piece), but is the min/max allowance of the RD limits screws usually big enough to make up for this?

  • when I did it the mech just about managed, but wasnt very happy in the biggest cog. I think it depends alot on the make/model of rear mech
