    Another Sizing Question

    Since I'm a tweener (5'6") and went with the small, what are some signs that I have set up my cockpit correctly? I know the forward most part of my knee should be even with the pedal shaft with the cranks horizontal. What about upper body positioning. When I sit on my Cannondale F600 in my usual riding position and I look down at the head tube I am looking down the front of it slightly, not a perfect shot down the center.

    Just wondering where the sweet spot is for upper body positioning (geometry) relating to the head tube, bars and front axle.

    First, start with the cleats.

    The pedal axle should be intersecting the ball of your foot. From there, set your leg extension so that you are comfortable while riding, with almost a full leg extension. While riding, if your pelvis is rocking back and forth to get to the bottom of the pedal stroke, drop the height a little. At this point, you set the fore/aft position of the saddle so that a plumbline dropped off the front of your kneecap will intersect the pedal axle. Be sure the above is spot on before proceeding. Now we go to stem length. In your natural riding position, look down at the front axle and the hub. adjust the stem length so that the handlebar is covering the front axle, or close. Remember, this is a XC position, and only guidelines. If you want to do it right, take your bike to a fit specialist, and get yourself fitted. Good luck.

    The bar crossing the front axle thing doesn't make since to me. If that where the case, according to my pic's, that means I would need a 50mm stem and a longer top tube would only make the situation worse.

    Just like I said, they are guidelines.

    Those are the typical setup tips to get a decent xc position. However, what works for one does not work for another. There is a good chance that you will decide on a shorter stem. My wife is slightly shorter than you are, and she runs a short stem on her F-900. (small) When looking at new Cannondale stems, ther serial #s reveal the reach and the angle. eg. 10035465 ca the first #s are the reach (100mm) the second number is the angle(35deg) the rest is codes for man. dates, and so on. Try posting in the General forum using an intro like "general bike fit setup" and the like. The tips above will be listed, I am sure. I fit bicycles for a living at a shop that deals with Cannondale, Trek, Rocky Mouuntain, and Specialized. (background)
