But my point is that you don't want to get rid of it by changing your hardware. You want to understand why you're getting it and solve the problem in your positioning, flexibility, etc. No pedal/cleat system will help if your body wants to twist -- you'll just damage yourself. So get your leg action straightened out first. That means (a) lots of flexibility and strength exercises, (b) get someone who knows how to fit you to look at your cleat position, and (c) adjust your position til your knee wobble goes away and then decide if you need new pedals.
Thank you for your clear and comprehensive information! The last 3 months I do a lot of core stability exercises and I ve been to a bike fitter as well. The last time I am fitting my bike by my self with the information of Steef Hogg. I am having also sport massages but still I have this problem. The Time RXS doesn't give me enough stability. Before I had the Look Keo max carbons.
For your informaton, I have Specialized Road schoe Pro (carbon) maybe these ones are not stable enough?
So you recommend me the SPD SL? What about the Look Blades?
