I wanted to share my story with my fellow bent riders.
I've ridden a DF all my life, but switched over to bents due to physical issues. I ride a solo and tandem bent, the makes do not matter. I trained hard on the tandem and completed a strenuous tour on it. I then went on an 86 mile ride on the solo the following week.
Now the problem...
I strained my left ankle. STRAINED, not broken, not torn, not ripped, it just hurt. The short story is 3 months in a walking cast and 5 additional months not on my bike.
Over extension of my foot caused a repetative motion injury. My pedals were too far from my seat. Are you kidding? I have NEVER been injured on a bike, until now. 8 months off my bike! It seems that the most comfortable position (I thought) was NOT GOOD! I recently began riding again and adjusted the seat PROPERLY and have no issues with over extending.
I did a lot of research on bent injuries and only found a couple of entries addressing this issue. I hope my experience helps identify a potential problem before it becomes a real problem.
