Cannondale. Everyone are for 1 1/8 so you choosing depends on frame and headset

If I'm not mistaken you want the one that says cannondale, just pick your preferred color. the other ones are for non cannondale frames. Seems like a lot money for very little weight savings and the ability to run a non cannondale stem. Although I want one cause I am using the tank of a steerer from project 123.

That´s me who build these Lefty steerer tubes, you should take a Cannondale , they all are with 1 1/8 tube to clamp a stem on.

The other question is if it´s a lot of money for a little weight saving?
Project 321 stated their Lefty tube for 1 1/8 frame is 149 grams, which mine hovering in around sub 80 grams, have made around 10 pcs in 66 gram mark with these so you get basically 2€ per gram saved, not too bad in my book.

Think about where you can lower a part with around 70 grams with 170 euro investment.

If you want a more bulletproof product, take a MCFK, they have good reputation and better availability.

You need a clamp to reduce from 1/5 to 1 1/8
