I recently picked up a Bombtrack Hook EXT frameset and I'm looking to move my SRAM Red eTap groupset over to it. I've been reading about bottom bracket standards, but this is my first time building up a bike from the frameset. I knew the bottom bracket was T47, but I didn't realize it would be so wide, and I'm not worried that my Red 50/34 GXP crankset's spindle isn't long enough. My plan was to pick up a White Industries T47 BB, but I could use some help to make sure I'm moving in the right direction.
Frameset: http://bombtrack.com/framesets/hook-ext-frameset/
Crankset: https://www.competitivecyclist.com/sram-red-22-gxp-crankset
Bottom Bracket: http://www.whiteind.com/t47
Questions:
1. Will that crankset fit that frameset?
2. If that bottom bracket would work, should I get internal or external? My previous BB was external, but I think it was 73mm wide.
Thanks!
