A few years back I thought about getting pedal extenders since my leg has been shattered
above & below the knee & has taken on a somewhat unique shape. The other leg didn't
fare much better with a shattered kneecap & 2 severed tendons. Anyway when I priced them,
I balked since they cost more than pedals which didn't seem right. At 67 I still ride more than
I drive, but my knees were starting to go, so I finally broke down & bought a pair. Now I
could just kick myself for not having done so sooner. They've made a huge difference in the
amount of stress on my knees as well as increasing the power I can put to the pedals.
If you're starting to have knee issues, don't wait; get a pair and see the difference. I just
ordered 3 more pr. for my other 3 bikes.
