This can be a harsh group at times.

Basically you're going to want to change things around and do something different in order to get different results. I recommend having someone videotape you while riding. Directly from behind and from in front is good. Then compare with video of a pro rider from directly behind or in front and you'll find your answer.

Good luck!

BTW - I remember seeing someone saying something so succint and perfect that sums it all up. Something to the effect that a bike in motion is in perfect balance; it goes in a straight line perfectly by itself. It's the human on top that makes it change directions or makes it crash. I've seen this illustrated hilariously with motorcycle racing. A guy wiggle-waggles coming out of a corner and crashes. The bike gets up and continues down the straight all by itself!
