Can someone help me out. Just want to know what is the bottom bracket for a SC 2013 7.8
I believe gxp. But just want to use my phone a friend on this one!
There are two compatibility issues to worry about when buying a bottom bracket (frame and crank). The 7series SC accepts a BB86.5. The gxp indicates that that BB will accept gxp compatible cranks (some SRAM, vision, etc), but not others (shimano being the main one incompatible)
To fit a gxp crank, get a gxp BB86. For, say, a shimano crank, get a BB86 Hollowtech

Is there an easy way to see what mine is for sure?
What crank do you currently have installed?
So you have the gxp bb currently, just replace with the bb86 gxp.
