Whoa, how much is that bad boy?

That'd be great when my ISIS Evolve FR BB goes out.

It's $80 at Speedgoat, but I don't know if it's any better than a regular ISIS. I'm hoping that someone can give a review.

Search the forums, think someone here posted before that they use a narrower external bearing that may have issues of it's own, but not sure if I remember that right...

In my search for info on this bb (which I still haven't found) I did find it for $50 here:

I'm riding the Megaexo ISIS (non-TI). Only have 2 rides on it. The bearings are not sealed cartridge, which was disappointing.

So far, so good, performance-wise. I wasn't hoping for much... really just another 18 months or so before I go for a real outboard set-up on this bike.
The floating-ISIS spindle that it comes with is interesting. I am thinking it could work with regular ouboard bearing cups (Shimano/Raceface)... haven't tried that yet though; maybe the next time both my bikes are broken down for major maintenance.

I believe FSA has already ceased production on these BBs (after only 6 months or so). They've removed them from their website. ISIS really is dead, guys.

This looks like an answer to the short bearing life of ISIS BBs. However, I looked at my Bontrager cranks, and I don't think I have enough clearance when used with this BB.
