I got the Cannondale expander off of Ebay. Them or Cannondale Experts always seem to have them.

What size bolt does this take? Couldn't find out online anywhere. Am thinking about using this with a different top cap.

Could the EE system be used on a Cannondale all carbon fork instead of the Cannondale compression cap?

Hi Shoe, that's a good question to ask. The answer is No. The Cannondale fork requires the internal support the Cannondale expander provides. This helps the steerer resist being crushed by the external force of the stem.

That's the same reason you have to be sure the internal expander is installed in the fork at the right depth to match the stem's lower clamp bolt.

You can read about this in the Owner's Manual Supplement (OMS) here: http://www.cannondale.com/en/USA/Suppor ... nuals/Road

For example, in the Super Six EVO (2012) PDF, it's on page 15.

Cheers,
Damon

And I would expect the same to apply to ANY carbon steerer!? The expander is a structural part of the system.. I wouldn't ever save weight in this area myself

And why do Canyon bikes come without any expander then? OK, 1.25" steerer tube, but the fork as pretty light @ 300gr cut, so no extra reinforced steerer tube IMO.

Exactly. Would my carbon stem with zero cut outs torqued to 3nm crush the steerer tube without the OEM expander? I don't think so

Hi Delorre,

Naturally, I can't speak for other brands. But looking back over the years, almost every major brand has had a strongly worded technical bulletin, or a recall, due to structural problems at the top of the fork. Trek, Specialized, Cervelo, Felt, just off the top of my head. I'm sure you can find others.

It's interesting that of all the international structural tests arrays required to sell a bike (ISO in EU, CPSC in US, etc.), there is not one single test required for the top of the fork.

Nevertheless, I can speak for Cannondale, and the message is: keep the stock expander, read (and follow) the instructions, keeping the expanding part in line with the lower stem bolt.

Cheers,
Damon

Been using a ultrastar for years on my caad9 fork and now on my evo hm. No issues. I'm sure recalls are due to dumb consumers just cranking down on stem bolts. Your average rider is clueless when it comes to carbon and torque wrenches.

I just got my ee top cap and can't figure out how to install it. It says to hold skirt with finger and tighten counter clockwise... my finger is not strong enough to hold it. Any tips?
