I went with the Tune Gum-Gum and the Soul Kozak top cap/bolt combo.....stupid-light and works great.

I'll add on another Extralite ultrastar, but mine with fibrelyte top cap is only 10g. Dropped 40 from the stock super six/fsa

I got slightly OCD with the whole top-cap and starnut ordeal and went with this setup. Overall, 9 grams for the top cap, bolt and expander, and it works perfect. I wanted the topcap to match the UD carbon weave of my stem. I don't like combining UD and weave together...ugly! Haha. I don't think you can get any lighter without removing the whole deal completely... which is uncool.

Extralite Ultrastar2 - 7g - http://fairwheelbikes.com/extralite-ult ... -p-29.html" onclick="window.open(this.href);return false;
Parts of Passion UD carbon top cap - 1.2g - http://fairwheelbikes.com/parts-of-pass ... -3708.html" onclick="window.open(this.href);return false;
Schmolke carbon bolt - 0.7g - http://fairwheelbikes.com/schmolke-carb ... -4846.html" onclick="window.open(this.href);return false;

The PoP top cap is few grams lighter than the Fiberlite, and also lays flat on top of the stem. I did not like how thick the fiberlite and how the edges are not rounded off.

Hey guys, Digging up an old thread here but wanted some feedback about some of the products here...

I have a 2012 C'dale Supersix and looking at swapping out expander plug and top cap. Because of the recommendations (thank you "2011") I have seen in this thread it has come down to these 2 choice.

Ultrastar 2 expander $42/7g (23.3-25.2 mm)
Parts of Passion UD carbon top cap $22/1.2g
Schmolke carbon bolt $20/0.7g

total of $84/8.9g

OR

Tune Gum Gum expander $17/9g (24.0 - 25.5 mm)
Parts of Passion UD carbon top cap $22/1.2g
Schmolke carbon bolt $20/0.7g

Total of $59/10.9g

I dont have a tool to measure the inside of my headtube, just to confirm will both of these fit?
Can anyone attest to the ultrastar 2 being a better product to making it worth the extra money?

I was in a similar boat as you, looking for a lighter option for my Caad10...
I'm holding off until these Cannondale units are available...

Have you seen the Carbon Fiber Headset Dust Shield produced specifically for the Super Six..? It comes in either plain weave or unidirectional carbon and weighs only .6 grams. Veloflyte also produces the lightest top cap at only 1.4 grams..! With the included aluminium bolt, the top cap assembly weighs about 3 grams...usually less. Not that I'm biased or anything...

Yeah I saw that, but the problem is trying to find one. The cannondale expert site said they had them on order back in october but nothing has been posted. Anyone have one of these or know where to purchase one?

I have one of these new cannondale expanders and love it. I had an extralite and was not that impressed. Oddly the cannondale is the same design for the expander but seems to work better.

If you buy a KP203 headset you should get this expander now. I also saw one go for $30 on ebay recently so they are starting to show up.

I sell them through my website veloflyte.com
All transactions go through paypal so it's completely secure.

Thank you

Do all expander plugs use the same size bolt? I see on velofylte's site that the top cap comes with an M6 25mm. I have seen others use an m6 16mm and then again others use an M5 20mm.

Whats the difference?

DAMN all the light weight caps are sold out on Fairwheelbikes. Veloflyte, I want yours, I REALLY do, but I cant allow myself to spend $32 (Dont know if shipping is included in that or not) on a top cap.
