Ok, I remeber back in the day when Cannondale was using CODA stuff and it bothered everyone because it was compatible with exactly nothing. I guess the idea was to make consumers replace Cannondale parts with Cannondale parts and to bother shops that were not Cannondale dealers by making them retool to deal with those few Cannondales that came through the door. Although they have dropped the headshock, the Lefty still poses some problems, but they have struck again with the HollowGram Cranks.
Cannondale claims that to remove the crank arms from the bottom bracket spindle you will need a specail Cannondale KT013 Crank removal tool. This tool runs about $50 and consists of two really small easily lost peices. In short, it is one of Cannondales annoying little ways to push you back to your Cannondale dealer, because no normal shop is going to bother stock this silly tool. On the other hand. If you look closely and use some creativity, you don't really need the tool, you can adapt your standard Crank puller to do the job.
WARNING: Do NOT simply put in a washer and try to pull the crank with your normal puller. Once you add the washer to contact the BB spindle there will not be enough usable threads on the crank for the puller to grab onto and you will strip the crank.
What you can do is the following.
1. Take a CCP-44 crank puller (the 22 will probably work as well) and remove the tip. (you know the part at the end that is roughly the size of a nickle that pushes against a splined axle)
2. unscrew and separate the handle/driver portion of your crank puller from the part that locks onto the crank (your puller is now in three peices)
3. Remove the Crank arm fixing bolt and washer from the drive side crank.
4. Thread the Crank arm fixing portion of your crank puller onto the drive side crankarm. (Note that this will have the same amount of contact as cannonales tool, so you won't have to worry about damaging the crank.
5. Now here is where you will have to be a little creative. Find a metal rod or bolt that will slide through the center of your tool and into the bottom bracket. I use a socket extender with a skateboard kingpin stuck in it, but an old hub axle cut to length might work jus as well. Insert you metal rod through your tool, through the bottom bracket so it comes in contact with the back of the Crank arm fixing bolt on the non-drive side. At this point, the bolt should sit inside the part of your tool that is threaded into the drive side crank.
6. Now thread the driver/handle part of your tool back into your crank arm tool. Tightening the driver will push on your bolt and drive the crank arm off the bike the same way it would if it were contacting the splines of a bottom bracket.
You do not need to remove the non-drive crank arm to service the bottom bracket, but if you remover the non drive fixing bolt, you may find that the other crankarm comes off on its own as the BB spindle is pounded out.
This system works well, and is a way to use a common $15 tool to do the job of a custom $50 never to be used again tool. Save you cash for buying cool new parts from you bike, don't let Cannondale sucker you int buying a new tool you don't really need.
Sketch of how this works is attached due to people not being able to understand what I was saying.
