It is a Torx bold and the tools are available at a hardware or better tool store.St. Elia said:Well thanks but, I have the BB, crank tool, I'm asking about the chairing tool. It's a special tool that is a star shape but with a special hole/shape to it.
The Bald Eagle said:I have never owned a campagnolo crankset only shimano, sram, bontrager and FSA. Looking at the campagnolo website I see the mention of a Torx T30 tool on the crankset installation manual. So I assume this is the size of Your chain ring bolts. I have a time trial bike with a FSA SLK Light Crankset that requires the use of a Torx T30 tool for the removal of the chainring bolts. I then purchased a 1/4 inch drive TX30 socket bit from Teng Tools Online which will exactly fit the Torx T30 chainring bolts. I then use this socket bit along with a torque wrench to secure the Chainring Bolts to the correct torque. A FSA T-3O wrench will fit Your Campy Chainring Bolts. This Tool can be purchased at chain reaction cycles. Northern Ireland.

Most bike tool companies sell them as do automotive tool companies.
Sorry I don't have the size in my head but T-15 or T-20 comes to mind

The Bald Eagle said:And if Your prepared to invest in a crankset for say $300 to $600 for example I don't think $15 extra for the proper tools will break the bank!! Torx bolts in My Opinion are a better option than Hex bolts. Especially those very light aluminum hex bolts that are very easily rounded with a allen key if one is not careful. Then you have to get the power drill out, stick in a metal bit of the correct size and drill Your rounded hex bolt out. I have never had that problem with torx Bolts. And I have had several cranksets with torx bolts.

Master50 said:"The 11-speed chainrings now have eight shift positions with pins and special tooth profiles at each. This is up from six shift positions (and from fourbefore that). The chainring bolts no longer have a female nut on the backside. Instead, they thread directly into the inner chainring and are tightened with a Torx key."

Quoted from a velonews article from interbike on the 2011 Campagnolo groupo.
My bolt comes off with a torx as I said. I cannot imagine what your cranks have that is different?
St. Elia said:Did you look at the pic? I'm talking about the small chain ring where it attaches to the crank arm. it looks like a torx key but has something in the middle that prevents me from using a standard tool. It's super record but not the 2011, not sure it there is a difference.
St. Elia said:Ok here it is. notice the inside of the star shape. the link above shows all of the bolts except the one that goes into the crank.

The Bald Eagle said:Here is an image on the Campagnolo Website that shows in great clarity ( the chainring bolt that is screwed directly into the crank arm ) the exact same chainring bolt that You have on Your Crankset, and that is shown in Your up linked photo. Trying to help here to give the readers a clearer picture of what is required to remove this chainring bolt. Notice the grey shaped piece in the middle of the t-30 bolt.
