What BB adaptor for flash?

I would suggest the Wheels Manufacturing BB30 adaptors... They are light, cheap, you plug them into the BB30 bearings and they are easy to remove if/when you want to upgrade to a BB30 crankset. Removing the metal sleeve type adaptors to use the Shimano BB will be heavier but also pretty tricky to take off, Cannondale even says (or used to) the sleeves are permanent... Just stay away from Enduro bearings if you need BB30 bearings... they will not last half a season in a mountain bike.

Why don't you want to use the Hollowgram cranks?

and what bearings do you recommend Dan?

Or why not XX BB30 if you can't get a hold of hollowgram?

And X2 to Dan.

Thanks for the advice guys,that looks like it will work.The old BB30 adaptor type sleeve that i had in my Taurine wont work but those http://wheelsmfg.com/content/view/785/54/ will do the job.
I'm selling the frame so having the adaptors will give me a bigger market,it's a long story but the frame is going to be sold.
Just in case anyone wants to know
Weight-1080g size M including seatpost clamp.
A 2010 S-Works HT M was also at my lbs at the time so i weighed it as well-1280g.
Cheers

Thanks for the info.

I second the Wheels Manufacturing BB30 adapter. It is Shimano specific and works great. Available in the QBP catalog.

I actually had to shim mine a little with a washer between the adapter and the crank arm. No idea why, but they said that Cannondale made their BB shells a little narrower.

Funny thing, Enduro have seen one of my bad comments about their bearings and seem willing to help/find out if I have a warrenty issue. But, I have had better luck with the Cannondale bearings (both ceramic and non-ceramic) than Enduros and there are lots of people not happy with the durability of Enduro bearings. Personally, I think ceramic bearings is way over-rated and more a marketing hype than anything. When I'll need new bearings, I'll probably stick with non-ceramic but high-quality bearings like SKF...

I have the OEM Cannondale BB30 bearings in my Caffeine. No problems. They were cannibalized from a road bike at my local bike shop.

I put just over 10,000 miles on my 2009 29er 2 in about 9 months. Best bike I have ever owned.

Can anyone comment on a BB91 vs the Wheels Mfg BB30 adapter?

BB-91 would require a much wider BB Shell than the Flash's. If you look at the Specialized's that are coming with the BB-91, the shell is wider. If you think about it, the BB-91 makes it possible to run standard spindle length Shimano crank on the wider, said to be stiffer, frames.
