Cannondale Aficionados / Owners

Oh it does come with all the bits, panic over...! just need to figure out the bb30a issue,

the only difference appears to be 5mm shell diff??

Assuming the frame is BB30a You'd need the 109mm axle and the Si SL crank was designed for 104. It will still bolt up but the Q factor might be a bit odd.

If it was an SiSl2 pair of arms then no problem.

I'm about to try exactly this.

With the 109 axle I assume?

so... I cant use these then? http://www.lfgss.com/conversations/288010/#comment13025057

I can only use sisl2 if i want hollowgrans?

You can use them. You will need the stuff below to make it work...

(just pretend you are fitting them to a synapse - this doc is pre CAAD12.)

Cannondale, why?

They wanted a wider, asymetric bottom bracket to accommodate the requirements of their evolving frame designs. Which required a new axle and new arm designs to retain a good q-factor.

I'm not sure if the above is telling you that you need a SiSL2 left hand crank arm to make it work...but it kinda looks like it. Weird.

It does seem so... Thats how it reads anyway.

So unless i can find some cheap twos, i need just Si's which are 109 (thanks @Dick)

Cant you use the ones that came with the stock caad12 Si chainset? *That is if you havent sold them yet

It does seem so... Thats how it reads anyway.

I think that's because the SiSL2 NDS arm compensates for the increase in axle length.

See what the results of are of @Dammit 's test. I think it will work, there will just be 5mm of extra Q factor somewhere, possibly all on the NDS.

Why do you need the axles? You already got it in your bike.

You're talking about your CAAD12 are you?

fuken cannondale and their bb30a bollocks

Exactly, the axles already come with the bike, simply swap the crankset over.

I predict lots of dicking around with spacers.

I never got an axle with my si2's. Can I use the one from the fsa cranks that came on my caad10?

No, unless you mean the Si crankset with the FSA ring.

Yes, I do mean that one actually. Thanks mate

anyone know where I can get spiderings? can only see them at triton and '7hundred' but both are to order-in rather than in stock..

Germany - preferably before we brexit

bike24 has them in stock

@mcmyk - previous page. Not sure if what you're after?

Is anyone on the market for a 53 / 39 SpideRing?

thanks all

can only see them at triton and '7hundred' but both are to order-in rather than in stock..

In the UK most cannondale parts are always back order to the mothership; very few suppliers keep any of their products on the shelves, and the 'distributor' operates on a JIT basis

And by JIT - four weeks after you request them

The German 'distro' operates in a different way by the sound of things.
