Our Left and Right stainless steel Hex⁺ (20mm) Pedal Spacers (Pedal Extenders) 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 (Pedal Extenders) are intended for pedals that DO NOT have wrench flats (pedals are attached to the crank arm with a 6 or 8mm Hex Key). Designed with a thru-hole to allow a 6mm or 8mm Hex Key for attachment.

Your spacers and quality service have helped me a ton!  Two years ago I compacted (fractured) my left femur (fell hard on the left side going slowly through hard-to-see SLIMY concrete under 1” of water - sheesh!) 

No surgery, and now I toe out on the left quite a bit for an ergonomic stroke.   Your spacers and cleat shims have made ALL THE DIFFERENCE!      Easy to install, last forever, sturdy, and customer service that can’t be beat.   Thanks for helping our bike tribe keep rolling!    I’ve got your product on road, mtn, cross, and tandem bikes!     Still racing in the geezer 60-plus divisions thanks to you.

I have been cycling for 12 years and just turned 40. In the past two years knee and foot pain have become increasingly apparent. I just wanted to thank you for making a proper product to resolve the issues i have have never had someone address properly. I must have read your blog post on pedal spacers a half dozen times before ordering a pair for my Ultegra pedals. Specifically the parts about stance with in snowboarding and running. The Hex + 20mm is exactly what I needed! I am so glad i read your post as i was ready to order the +4 mm pedals Shimano makes and this was 1/4 the price.

I use your 20mm hex pedal spacers and have done for a few years on all my bikes with great success in alleviating knee pain!
