the innicycle stem/headset conversion is a nice "modern" alternative to a quil stem, and right now my only question has to do with the "steerer tube slippage" or pivot around with enough stress of the stem on the tube it attaches to. the mnftrs send it with a semi polished surface, without the dull finish friction you get with a "normal" steerer tube in steel/alum/CF. not sure the best solution to add the friction albeit spray mount stickiness or a primer paint to metal. its an issue, surprised they made it this slick.
otherwise, it was a good install and yes, worth the 130.00.
after all, a decent stem after shipping runs 80.00 and a decent headset around 60-90 or more depending on what you want to put on(chris king much much more).
I'm not sure the griping about cost, this is an upgrade unless you love your bar and stem combo, which many who have had their bike dialed in for yrs do. others who buy an older beautiful frame but are retro building with newer components, the innicycle is the only good alternative without using the butt-ugy adapters available otherwise.
