I need some advice regarding bottom brackets and crank set.
I have bought courtesy of cycle to work, SRAMs red Etap wifli groupset and I have ordered the Ridley Fenix SLX frame but I need some help on what BB and crankset I need. It’s just confusing.
Ideally I would like to stay with SRAM red but their choices are GXP, PressFit, BB30 and PressFit 30. I don’t know why they are and which one is best.
