Mark: It’s not a Bushnell type, it’s a simple design. Think traditional EBB shell. Okay, now think of an insert that will house the bottom bracket that is split in two perpendicular to the bottom bracket. So you have two sides to the EBB insert, okay? Now the two halves are held together by one bolt, ala Campagnolos Ultratorque crank set. What stops the two halves from spinning in the EBB shell are the flanges on the outside of each half of the insert that contact the EBB shell “face”. (Much like a cartridge bottom brackets driveside cup does, only this insert isn’t threaded)

So, we have three pieces to the whole she-bang. Two halves and a bolt that draws it all together against the outer edges of the EBB shell. To tension the chain, simply loosen the bolt enough to spin the insert.

NoWayRay: Yes, this should retrofit to any traditional pinch bolt type EBB, as far as I know.

No for split shell type EBBs where the shell surrounding the BB is split and held together by pinch bolts to allow adjustment but yes to Phil Wood type EBBs where the BB is held in place by a sturdy bolt screwed in at a right angle to the shell as a ” stopper ” to allow adjusting/fixing.

Any idea whether this new EBB will be retrofittable to older Niners?

That’s a Bushnell EBB isn’t it? They’re lovely, been around for years and you can bathe them in mud and they come back looking for more.

Beautiful! Still one thing keeps me from buying it, to me it is kind of counter-intuative to make a Really light bike/frame disc-specific.
Yes, there is the “the frame is light so you Can run disc” arguement.
If you go That light on the frame, you might as well go with carbon v-brakes!
