BikeFit pedal spacers will correct q factor issues and problems to do with crank width.
If you are reading this you must be aware of some issues with your bike fit, or you have had a professional bike fitting in the past and they have recommended pedal spacers.
These Left and Right stainless steel Hex+ (20mm) spacers (Pedal Extenders) for Look Keo (and related pedals ) are used with knees that track outside the pedal by adding length to the pedal axle.
Designed to move the foot out and away from the crank arm to provide more foot clearance, they add to stance width for cyclists needing help with knees-out, excessive toes-out, extra wide feet, wide hips, or for those with discomfort on the outside of the knee.
These pedal spacers work with pedals that do not have wrench flats (pedals are attached to the crank arm with a 6 or 8mm Hex Key) AND pedals that have wrench flats.
Not intended for use with Carbon Crank Arms.
Let's start by saying that cleat wedges should be prescribed by a bike fitter. However, if you prefer to experiment based on others recommendations, then look for the following signs.
If you have a turbo trainer, place a mirror straight ahead and watch your knees. Visualise the movement of your knees. If they look as if they are "poking" outside your hips, flaring a lot and your leg looks as if it is driving towards the frame, rather than straight down towards the ground then you should consider pedal spacers.
If you don't have a turbo trainer, and you have the right saddle height (i.e. not too low) then consider a pedal spacer if you cycling buddies tell you your "knees stick out when you ride".
