    Weight difference Cannondale 1.125" vs. Project 321 steerers

    I am going to pull the trigger on a Lefty Max RLC for my Yeti 575, and I am going to decide between the Project 321 or the original from Cannondale. I am going to use the P321 hub for the front wheel anyway, but I want the best deal on steerer both weight and cost-wise.

    The Cannondale steerer is 220 grams uncut (290 mm):

    I think the P321 is just about the same, maybe a little lighter...? (160 grams for the P321 has been mentioned here before but I don't know the length of that one...?)

    Ok, then I will go for the P321, then. At least i will know it is available (the Asian Cannondale distributor told me the steerer was not available yet, but then others have them in stock...)

    P321 is actually the original. The C'dale steerer is the new kid on the block and mysteriously very similar to the P321.

    DekerfTeam, I like your style..... "mysteriously"

    To be fair to Cannondale there is little you can do to change this adapter. I mean you are constrained by the i.d. of the crowns and the o.d. of the steerer tube. And they had to
    drill the holes like we did or they would be a brick. So really, they had little room for a design change. But I have heard that ours is a little lighter still.

    The big question in my mind is since they come with a headset are you confined to
    use that headset? What if you want to use your favorite headset. Anybody know how that works?

    hssp - feel free to e-mail us with any questions regading your project. We are always here to help.

    I have seen it available on www.cannondale-parts.de in 4 versions. Standard, hiddenset, zero stack and plain (steerer only).

    Jake, thank you for your offer to help. I think I know what I need now, and I believe it is needless to say that it will fit the XL clamp width.

    Are there any headsets that are known to work well/badly with Lefty 1,125" steerers? I have a CK one already that I plan to use.

    The CK will work fine with one small modification. You will need to split the crown race.
    That allows the crown race to slip on to the steerer tube. That is critical because the king crown race is larger than the inside dia. of the lower lefty crown. I have done this many, many times and it works fine. It just needs a small slit and to be well deburred because you want a good contact with the lower bearing and it will go together like butter!

    Kohosis all aluminum 136 USD + 20 USD shipping. Weight probably 140+ grams, non customizable.

    Project 321 89.95 USD + 12.26 USD shipping, Weight well over 150 grams, non customizable.

    EP Lefty steerer from 195 USD + 9 USD shipping, weight from 76 grams upwards, full custom in colors and type.


    If you all do think the 70+ grams weight saving is not worth 60 usd, let it go.
