  • Hollowgram si cranks on a non cannondale frame - yay or nay?

    I have a new frame coming, Specialized with osbb. I was going to sell my bb30 hollowgrams and potentially go with something else.

    But I've realised I can have the arms re-anodised into a colour that might suit the frame and avoid having to buy new cranks.

    I have two of the spacer kits so getting the cranks installed and spaced correctly shouldnt be too hard. Would I be best installing the cranks as if its a cannondale frame as per the instructions here https://www.cannondale.com/-/media/files/manual-uploads/manuals/SISL2_Road_Crankset_Instr_1012.pdf

    Anyone done this? Any issues to look out for? new frame is an sl6 tarmac

    edit - can anyone recommend a place in uk that could do custom lazer etching to have the logos put back?

  • IS OSBB 68mm wide? If so install them in the same way they'd go in to a CAAD10, which is basically a large 5mm hat looking spacer on the NDS assuming you have the 109mm axle.

  • Confusingly specialised us the OSBB term to name pretty much all of their bb's
    But it is 68mm wide.

    All of this has reminded me that I had to use a non standard spacer set up on my caad10 to get a good chainline and for the arm to sufficiently clear the etap front mech. I imagine this ball ache will happen on the new frame...

    Just looked at my arms, I think you're right. Dont see any of bonding lines that can be seen on the sisl canks
