ISIS w/ External Bearings for replacement?

[Scott Gordo]

I've got a set of Raceface Turbines with an ISIS bb that's churning
its way to oblivion. Does anyone make an external bb that works with
these cranks? I found this:

but I think it only works with new versions of ISIS splined cranks.

TIA.

The manual says "Compatible only with Howitzer system crankarms". Even
if a standard ISIS crank fits on the spindle, the chainline will be off
and the tread will be noticeably wider.

Working well so far on the MTB under wet and muddy use.

ISIS and external BB , 2 piece systems are not intercompatible. Get
some spare ISIS BBs or new crank.

Yeah, I thought about that. I guess the interface point on newer
versions of the external ISIS cranks are much narrower?
