Those are not bbright frames, I think you could make hollowgram work with zip cups on a standard bb.

From what I can tell all the bbright hollowgram axels are custom made, they are modifying existing cannondale axels.

there is hope that raceface/easton will make a next sl road crank. : )

Sorry to bring back an old thread but looks like there are more axel choices if you can find them

Double check my math but without spacers 119 should work..

and there is a 125

Also the easton and stages axels should work to but they are super wide

...bsa30 cup... english threaded frame...

I had no idea that was even a thing, would this mean that it's possible to fit a bb30 (or another kind of 30mm spindled crank) into a BSA threaded frame?
I thought that wasn't possible and you could only fit ones with a 24mm spindle (eg. Shimano, SRAM gxp)

As you can probably tell bottom brackets and cranks really leave me confused at times :?

EDIT: Probably should have read the rest of the thread before asking my question :oops:
This answered it very well:
30mm ID BSA external bearings won't work for a true BB30 crank. They add about 10mm to the 68mm BB width on each side. Cranks with long 30mm spindles like Rotor and Sram Quarks will work.

BB30-83 Ai is 83 wide and BBright is 79

So a BB30-83 Ai axel should with with 3 or 4mm spacers with a BBright bike.


PS from the post it sounds like BB30-83 Ai is super new.
