BB30A chainset option - Cannondale CAAD12
Moderator: robbosmans
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.

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.

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
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!

Anyone fit a BB386 crankset to a CAAD12 with the BB30A and successfully set up a Di2 FD and have the crankset midline?Ltyarbro42 wrote: ↑Mon May 08, 2017 9:05 pmBB386 fits so that should open up some options. Also, something about some of the rotor cranks fits if someone could comment.
Reason I ask: my LBS said that an 8050 Ultegra Di2 FD would not work with my Lightning crank without spacing out the NDS crankarm several mm’s.
I didn’t try setting it up myself but his explanation did not add up to me. The chain line on both the crank and that FD are 43.5mm. The shell width is 73mm (5mm extra on NDS) and spindle length is 86mm. So I think 9mm of spacers on the DS, 4mm on the NDS would center the crank and put the chainline right where both the crank and FD want it to be.
Anyone use this combination successfully? Thanks in advance.

Thanks, I was not familiar with that brand. Looks like good stuff.
The BB does not seem to be the “problem” per the LBS, rather length of crank spindle on a BB386 not allowing a Di2 FD to be set up on a CAAD12.

Yes, and I'd like to clarify from my earlier statement that it is a Rotor 3d+ that works great as that's what I now have.
FSA has a spacer kit for the bb386 to bb30a that you should get, but in my case I had to add a few more shims plus a wave washer to get the compression I needed.

Morning and only just registered on WW. Wanted to send a message to Ltyarbro42 as could not send a pm until I have made more posts. I am about to pick up a caad12 and wanted to fit my rotor 30 chainset. I was wondering what spacer I needed for the none drive side (I assume this is the only side I need?) and you seem to suggest some wavy washers or a kit from FSA. Any further help on what you think would suit me best would be appreciated
