I ride Sidi Genius 5.5 HT Carbon shoes (size 42.5) and Speedplay Zero pedals. I am a Cat 1 experienced racer who is trying to dial in an efficient and comfortable pedaling position. For some reason I am unable to wear this comfortable shoe/pedal combination and have a powerful pedal stroke. I always feel like I am toeing with each pedal stroke. I've done everything from pushing the cleat as far back as possible to bringing out the dremmil tool and drilling some extra room (compromising the strength of the cleat). Riding shoes all come pre-drilled for popular cleat/pedal brands. I have switched pedals and shoes a few times, however I still run into the same problem. Sidi shoes and Speedplay Zeros are comfortable and I prefer to somehow stay with this combination.

I recently tried positioning my cleats farther back (from the ball of the foot to a little behind the ball). I did not make any adjustments left or right on the cleat, I just slid it back a few mm's. I did not make any adjustments to the saddle height or fore/aft position after the cleat relocation. I noticed a more "stable" feel from my feet, which felt good. After a longer distance I noticed a little 'tinge' from my upper right Achilles area that I hadn't felt before. Not really painful, but a twinge that seemed to tell me something was a little off.

I have seen a few options on choosing crank length, but I want a better one. I am 6'5" with a 39.75" inseam, and have a size 14.5 US foot. I run 180 cranks, and feel great on them. My riding style is relatively high cadence like 95 to 99 rpm for long rides, and above for criteriums. I have a few friends who tell me to drop to 175 or 177.5 cranks for better performance. They all site the rumors of Lance Armstrong running 165s stamped with 170. However I'm stuck in the thought of 180s being anatomically correct for me. My question to you is how can I use a Computrainer (I think that would give the best data with power and pedal scan) along with switching between 180s and 175s to see where the advantage lies for me?

I am finding in events where I use my time trial bike that I experience pins and needles in my left leg (my weaker side). It starts in my toes then my foot but eventually continues up my leg. I don't have this on either my winter training bike or my road bike. Neither does it occur on my right leg. I have tried various positions to alleviate the issue (higher bars, shorter reach, change of saddle height, tilt and even a narrower saddle) but the problem continues to persist.

I have read most of your bike fit articles over the past year or so and have implemented most of the suggestions with outstanding improvements in fit and comfort after several years of riding with the saddle too high, cleats too far forward and increasing pain as I age (60). Every one of the suggestions has improved comfort after trial and error as suggested, and usually in the direction where you identify the largest percentage of relief from something amiss.

One problem remains: I have an arthritic condition in my lower back that makes the 'balance test' problematic - I can't stay bent over the bike with no hands long enough to determine whether it's stable without having to grab back on before I lose control or suffer substantial back pain. While I can ride with no lower back pain with hands on the bars (something I couldn't do with the saddle forward and the back effectively arched), I just can't carry all the weight with the torso alone. I still get some shoulder pain and hand numbness on long rides and I can't figure out if this is inevitable or just an old habit I can't break, or something that could be helped with further positioning. I have often found myself tensing my shoulders towards my ears with no particular stimulus, and I can relax comfortably without pain if I keep myself conscious of this, but the event creeps back when I concentrate on other issues while riding.

I have been getting pain along the outside of my knee cap and also in the muscle just above and below the knee cap to the outside. All my pain is on the outside of my left leg, never medial, posterior or anterior. I only have pain in my left knee. My normal foot position is for my feet to face outwards, duck footed and I have adjusted my cleats to accommodate that position. I have just switched to Speedplays and I have narrowed my stance, but I am still feeling pain.

I was happy to finally see these questions from Viktor Recina and Robin Valdes, and thought I would share my experience with this problem. I have had symptoms identical to those described by Viktor and Robin, and though I've done much searching and had seen a few doctors, I had not yet heard of anyone with similar problems and no one could give me a diagnosis. However, the diagnosis of a muscular myopathy surprises me since I have found that my condition has gotten better over time.

I am a 25 year old cat 1 racer. I first had these symptoms 5 years ago as a cat 4 after taking 3 days off after a summer of consistent training. This first time was the worst - I couldn't walk or even stand up without extreme pain. It took 3 weeks for the symptoms to go away enough to ride again. Since then, I've had the same symptoms once or twice a year in similar circumstances, sometimes after just 1 day off the bike. Since I could find no explanation, my solution was to try to avoid taking a day off riding as much as possible. However, I have noticed that the severity of pain, and time required off the bike has decreased with each episode. Though it still happens sometimes, I don't need to be as careful as I used to be, and I am usually back to normal in a few days.

My question is what is my engine speed when I am cycling? My heart rate is now about 60 when relaxed (previous low was 42 bpm). Is my heart beating faster by ~20bpm regardless of my activity level, impairing my performance when cycling? It is normally between 140-160 when I am working hard, and I do not feel the effects of the hyperthyroidism when I am cycling, but am I endangering myself by continuing to cycle?
