Hi all. I am putting together a scott foil and want to put sram red on it. I have bought a sram red chainset that is bb30 as i was going to use it on another bike. This does not fit the foil as the shaft of the chainset is too big to go through. It says on the bottom bracket of the foil BB91. any idea what sram red chainset i need to buy would be a great help! And im building up a parts shelf bigger than i really need here.

Would it be a gxp one? Silly question for many i guess and i know a lot about bikes and do all my own work but bottom bracket seems to be a subject to me like algebra was at school and i avoided that like the plague too.

Cheers for any help
