How do you know when your "Q factor" is right?
Bought some Speedplay X-5s tonight and I'm kind of having a problem dialing in the lateral cleat position .
How should you feel fit-ise when you have your Q factor is correct? Is it better to have your feet too close together rather than too wide?

Seriously, you don't need a laser to do this, a plumb line will work. While straughtis a good place to start, it can vary depending on the rider's ergonomics and comfort.

I am not an expert in bike fit but don't think that cleat positioning is truly an adjustment of Q factor. Cranksets have different Q factors (distance between the outside surfaces of the cranks where the pedals are mounted). Some pedals are made with Q factor adjustments (you can adjust the "spindle length") but Speedplays do not offer that adjustment. I think that Q factor determines the alignment of the knee and the foot. Cleat adjustment, on the other hand (or foot, as it were), should establish the best contact point of the pedal with the foot.

I always try to get it so I am close to the cranks as possible.. When the back part of your shoes rubs on the cranks, you are too close.

It would be really cool if once, just once, Americans would act like they weren't all a bunch of thirteen year olds about the human body. What I mean to say is, it would be great if none of you prudes clicked on "Spam" for Lectron's post, and just act like an adult, but I know you will...(It'll probably be the same person who foamed at the mouth over Buycycling's "Sex Issue." )

hello
My Q factor is all over the map as they vary greatly from my track frame to my mountain bike. Never really cared about it.....

Pheasants! You probably use a saddle too dont you. No saddle here. I like that direct to bike feeling. plus no saddle, pedals or handle bars means less weight. Yeah i just stick my finger in the stem and turn when needed. No brakes like those fixe kids and i manually change my gears by moving the rear derailleur by hand.
