I just picked this up on ebay... I'm about to buy components for it and have a few questions:

Front der clamp on? What size clamp?

What size seat post?

I just picked this up on ebay...........


What year is it ??? There is a difference.

Auction states 2006

I am pretty sure it is a 31.8 FD clamp size and 27.2 seat post. is the bottom bracket SI or threaded, if its integrated you should buy my cranks... seriously though thats the biggest thing with cannondales, crank selection, though FSA and Zipp just jumped on the BB30 wagon

you should buy my cranks...

Haha the frame came with the cannondale si cranks:)

Thanks for the info on the FD and post!

If it is a 2006, the aluminum seat tube is tapered. It would use a standard seat post but, the FD uses a 34.9 clamp !! At least that is the way my 2006 Six13 Team edition is.

I just got one of these too!! The seller has zero feedback, but I think I know who he is anyway, and he shipped the frame via fedex to me the day after I paid. Brand new six13 with clearcoat and carbon top and downtube for under $600....sweet!
I too was wondering about the fd clamp size. Doesn't seem to be a clear answer....I've emailed Cannondale support, hopefully will hear from them on Monday. If not, I'll just call them, they are always great over the phone.

Cool, good to here the seller is reputable... I didn't really know what these went for, but mine didn't reach the reserve and as the high bidder he sent me a second chance offer for the item ending price $415.99 + $30 shipping:D What are your plans for building it up?

Please update the thread with cannondale's response...

I have a Colnago EP that I had Dura Ace 10 on. I'm taking the parts off that to put on the dale. Probably just pick up a new DA 10 group towards the Summer to put back on the Colnago. I've owned a Six13 in the past, and loved it. Had to sell it at the time to finance the Colnago.. :)
I'll post when I hear back from Cannondale about the clamp size.

Uhh... Am I missing something? Why don't you just measure the tube diameter?

Yes you are missing that I do not have the frame yet, and would like to order the parts so they can arrive around the same time as the frame...

+1, same here.

Conekilla, probikekit.com has a good selection of clamp adapters (if you happen to already have a braze on) for about $11 with free shipping.

The original Six13, with 3 carbon tubes used a 31.8 FD clamp. The newer ones use a 34.9 FD clamp.

Just heard back from Cannondale, as well as the seller, and yes, sounds like 34.9 is the correct size.
