Looking to change chainset on my 2011 Addict
It came with Shimano Dura-Ace Integrated SMI-FC 7800 i believe.
Looking to fit Sram red or force but will it be a straight fit or will i need a new bottom bracket also.
If so what size/ type would i need?

    The FC 7800 is a standard threaded fit.

    You will need a GXP BB and suitable cranks to fit.

    Have Read of th info on Parktools.

    Any of the gxp bb from sram will fit. Its a simple swap. You need hollow tech bb tool with a special thing to remove the cap for your shimano crank.
