Replacement SRAM GXP Blackbox Ceramic BB
I need to replace my SRAM GXP bottom bracket but can't find if it's a 68 or 70mm? What exactly are those numbers and is it a big deal? I'm thinking it's most likely a 68mm since that seems to be the most common. The only other numbers I see are a 47-08 and a 40-..... Don't see any 68 or 70mm
Thanks
Thanks

They only come in English or Italian thread, choose the thread type you have, length is standard for road External BB's on modern bikes (68mm)
