External Bottom Bracket (FSA Mega Quad)

AFAIK, the FSA MegaQuad is not an "external" BB ...

Post a picture of what you have -- the Crankset AND the Bottom Bracket.

It could be this one. Mega Exo QUAD MTB BB-7550 Bottom Bracket Cup Set

Oh, I see ...

Thanks for posting the picture -- if I weren't living-in-the-past & currently wedded to an Octalink crankset on my antiquated MTB, I might be keen to get one of those (now that I know that they exist!) ... if I had a bike with an 83mm (!?!) wide BB ¿shell?, that is ... unless, that's the total width between the outer faces of the cups.

But, the original query seems peculiar -- doesn't it? -- UNLESS he (sopel) doesn't already have the crankset in hand.

• all cranksets use specific BB-types, and vice-versa; so, presumably he wants a MegaExo crankset ...
  
• unless that particular BB is part of a proprietary system (e.g., a Mega Exo II system) , the spindle should already be attached to the driveside crankarm of the MegaExo crankset
  
• FSA MegaExo & SHIMANO Hollowtech II are interchangeable
  

oh yeah! I get it now 🙂 Thanks a lot people- now I know what i need to buy 🙂
