I have a new Cannondale CAAD12 frame that I will be using with a super record groupset.

Since the BB30A BB is rather problematic, I'm assessing what options I have for the chainset.

There is an interesting BB30A adaptor for Campag chainsets. E.g. http://www.ebay.co.uk/itm/Ceramic-BB-Bottom-Bracket-Cannondale-BB30A-adaptor-Campy-Ultra-Torque-Crank-Set-/132154110758?hash=item1ec4ffb326:g:CyoAAOSw44BYSgJw which would enable me to use a standard Chorus/Record/SR chainset. However, these chainsets are themselves expensive.

There is also the specific Cannondale Hollowgram chainset e.g. the https://www.sigmasport.co.uk/item/Cannondale/Hollowgram-Si-Crankset/DQY6?s=1 at around £350 in the UK.

I'm budgeting around £400/500 for all of this. What would be the best bang for buck here?

I'd prefer a Campagnolo chainset to be honest, but they are pricey! I could only really justify Chorus level (Record and SR seem very expensive).

One wild shot is the Sram Red chainset. Full carbon beauty that can be picked up for around ~£300 here in the UK. Is this unthinkable? Or would it be ok with decals removed.

Thoughts very welcome :)

BB386 fits so that should open up some options. Also, something about some of the rotor cranks fits if someone could comment.

All 30mm rotor cranks will work as they have longer spindles than standard BB30 cranks

Go with the Sram Red, remove the decals and put some lighter chain rings on (eg: Praxis) and you have one of the lightest and cheapest yet most reliable crank sets available.

Just make sure that you get the version with the plastic bearing adjuster (which you need to remove for BB30A) or it won't fit.

There's a Powertorque BB30A bearing cup so you could run a Potenza chainset. Not the lightest maybe but very current.

Thanks GJ,

Is there a different specification for the crankset with the plastic bearing adjuster? I can't find anything online which would enable me to know if it has/hasn't this.

Thanks!

There may be a different part number but the online shops don't list the part number anyway, they all just say Sram Red crank.

However I'm pretty sure that all the newer cranks have the plastic adjuster. So I think all Exogram BB30 cranks now come with the plastic adjuster. And it is the Exogram crank you want because it's lighter than the old model :D :beerchug:

But to be sure, just check the image of the crank you are buying on the shop web site. You should be able to make out the grey plastic adjuster ring next to the non drive side crank arm.

Good luck!

Thanks @ Gearjunkie

@Miller - could you provide a link for the Powertorque bearing cup?
