Thanks to all above. Good to put some of this on the record as much hasn't been previously explained. Ben...a terrific review of the two different BB's and the installation procedure...makes sense now. I see where the MegaExo gets its name...how appropriate....those cups are Exo or external and are Mega alright...huge. BTW...is the Q-factor/chain line affected with the MegaExo BB as the cranks I would think would need to be mounted more outboard of each side of the BB shell with those cups which house the larger cartridge bearings?

Speaking of same...does anybody know off the top if Park makes a splined tool that will engage with the MegaExo cups?...am presuming a splined spanner wrench does not come with the MegaExo....or does it?. The MegaExo cup spline... unlike the more conventional ISIS BB, looks unique to this particular BB is why I ask.

And 53...as usual we are on the same page and I too have considered heel scuff on the black crank arms. No dodging the graphic scuff issue as you know even with aluminum finish crank arms. What I do currently is cover my graphics with a clear mylar film tape...otherwise the graphics would wear off as well. My bike has a lot of black...wheels...bar tape etc...so a black crank and rings may look sweet.
Gustav be sure to share your review when you get your Gossamer w/MegaExo Compact installed. Would love to see pics as well.
