    ISIS Drive is a BB type, not a model. So it could be that you have a set of really nice cranks or really crappy cranks, depending on what model they are. If they are extremely nice cranks (and they might be since the rest of the bike is XTR) then it probably makes sense to just pick up a new Titanium ISIS BB and hit the trail.

    That said, you won't find many ISIS enthusiasts out there. The bearings don't last very long and every crank manufacturer has pretty much moved on to external BB types. Trouble is, the high-end models that are light weight are all going to be expensive. Check out the newer FSA offerings, or maybe an XT unit from Shimano. Not as sweet as XTR but certainly good.

    FSA Alphadrive. No, not really. One of the cheapest cranks FSA offers. I would definitely replace it if you want something at the same level as the rest of the bike.

    You can still find new XTR 960 cranks at close out prices. You can also find quite a few XTR 960 and 970 cranks on eBay that are either new or lightly used. The same goes for FSA K-Force and the higher end Truvativ cranks. Do a little research -- you may be pleasantly surprised.

    I have ridden ISIS bb's for quite a few years, and have had zero problems with them. I had an external bb on a bike i bought a few months ago (singlespeed), and the bearings lasted practically hours, so i bought an ISIS bb and cranks for it.

    I have a Crank Bros Ti ISIS bb, with FSA Carbon Pro team issue crankset. The combination is very stiff, and very light (plus the carbon cranks look awesome).
