Is Bottom Bracket is included?
Is Bottom Bracket is included? If so is it BSA ISO? or can it fix into a 33.6 mm bracket (Genius Team Diablo Carbon Frame)

This will not come with a bottom bracket and you will need to ensure you purchase the correct one for your frame. We don’t sell this frame or we would advise you which one would be compatible.
There are currently four chainset/bottom bracket interfaces that you're likely to come across. If your bottom bracket is made by Shimano and it has splines, then you need an Octalink chainset. If your b/b is NOT made by Shimano and it has splines, it's almost certainly ISIS. There are a very few non-Shimano chainsets with Shimano Octalink interfaces so, to be sure, count the splines - ISIS has 9, Octalink has (surprise, surprise) 8. No matter which brand of b/b you have, if it has a square interface, it will require a traditional square taper chainset. If you have one of the new Hollowtech II systems, you will need to choose the exact chainset that matches your bottom bracket. Most MTB chainsets are now 9-speed compatible but these will work with an 8-speed system.
