• PRICE DROP Cannondale System Six Team Si Carbon/Aluminium Frame. Size 54cm. Probably one of the best frames ever made by Cannondale, certainly one of the best looking. The front forks are fully carbon, giant carbon head tube carbon top and down tube mated to a fantastic aluminium CAAD rear triangle. This is known for being a very stiff, but compliant frame. A real, modern classic. Overall in good condition, just a bit of blemish under the top tube. £500 + postage. PRICE DROP to £400 + postage and any PayPal fees.

  • Awesome frames these.

  • Yes, always been my favorite, especially in the raw finish. I wanted one as soon as I saw the build Dammit did. Unfortunately, this must go.

  • What bb does this take?

  • English, threaded BB

  • Rotor among others do a BSA 30 adaptor to fit BB30 cranks into a BSA bottom bracket.


    BSA30 68-73mm ceramic red - 96g
    BSA30 68-73mm steel black - 89g

    • Designed to work with BSA threaded bottom brackets and 30mm axle cranksets
    • aluminum alloy 7075 100% CNC-machined
    • Silicone seals
  • That might be a press fit BSA adapter.

    Although there are some late and lower end model System6 and Six13 frames that have BSA bb this doesn't look like one.

    The Rotor BSA 30 lets you fit 30mm cranks (Rotor, some SRAM) but not 'real' BB30 cranks (hollowgram, OS/BB)

  • It could be, I had always thought the majority of System6 frames were BB30. I have not really investigated it too much, as there was no need for me to do so, but always thought it looked like there was something "extra" in there. Not sure how to tell without trying to press out the BSA adapter. Would be good to know, especially as I am trying to sell it. Any fail safe way of knowing?

  • Thats a BB30 shell with a BSA threaded adapter sleeve pressed in. They can be removed to fit BB30 again but can be a bit of an arse to press out! Lovely frame GLWS :)

  • From what I remember when I had this done on my CAAD9, it's potentially dodgy on a frame with a carbon bb shell.

  • Inclined to agree - @5hrine: wouldn't bother trying to press it out. Leave that option for the new owner :)

  • Every time I see one of these come up I miss mine.

    To eBay!

  • Thanks for clearing the B/B up. Fortunately it's got the alloy version, so probably not too much of a pain. I keep looking at @Dammit build again and wondering if I am doing the right thing. Main reason for selling is an elbow injury causing lack of flexibility. I don't want to build it up as a "comfy bike "as I already have one of those and I think a good groupset and nice wheels is the only way to go with this frame. It just wouldn't feel right with a set of riser bars and a stack of spacers!

  • ...just to clarify the bb adapter would not put me off buying this, great to have the option on what is an eccentric and very capable road frame 👍

  • Edit: drunken disrespectful offer removed

  • .

  • It is still for sale. But I am trying to hold out for the full £500!

  • Probably shouldn't be on eBay too you know.

    Tsk tsk.

  • Didn't know the correct selling etiquette, so trying a few places. Should it be pulled off ebay?

  • I think - and correct me if I'm wrong - that here the rule is 'on here and nowhere else'

  • Thanks for the info. I will need to pull it of here unfortunately, as I have someone mid offer on the other place. As soon as I have sorted out the possible sale I will update things here.

  • This thread is trouble, I am now actively searching for a System Six frame again.

  • ebay buyer did not work out, so now removed from ebay! Price reduction to £400 + postage and any PayPal fees. Is's all boxed up ready to go now, just needs a new home!

  • Anyone know what never happened to this one? If anyone has one for sale, 52 or 54cm, hit me up!

  • Someone bought it in the end. Shame it needed to go. May start looking for another.
