I am a 42 year old male rider doing recreational rides, usually a mixture of hills (30-50km) once or twice/week and then a longer flat ride (100km). I started riding again about 12 months ago and feel I've built up my fitness to a reasonable level. But I have a persistent problem with pain at the rear of the right knee. It can be helped with hamstring stretches as well as stretches for the top of my calf but after a long ride the issue re-emerges. Self-massage shows the area is painful. I also feel my right hip is noticeably less flexible than my right.

I did have an older bike (61cm) but have just upgraded to a 60cm Trek Madone. I was hoping with a current bike fit the issue would sort itself out but no joy. I have noticed that my left shoulder is higher than my right, and has been so for some years. Like most of us I work at a desk and computer. One bike fit chap mentioned that core strength is often lacking in people who work as I do - but could this be related to the knee pain? FYI I had two bike fits done (one for a prospective custom-fit bike); both came out remarkably close.

Per the ongoing dialog discussing the relative benefits of mid-foot cleat position, I have some rather run of the mill inquires. Like most training techniques is this something that one should introduce into a training regime early in the season or is it liked to something similar to switching to Q-rings which most users report taking a handful of rides to adapt too? Also for those of us with shoe/cleat combinations that prevent true mid-foot setup, can we expect some (although lessened) performance gains by moving our cleats as far back as our current shoe/cleat combination allow and would this change be recommended by the true mid-foot converts?

The limited empirical data and biomechanical descriptions all make sense to me however I've be racing long enough to know that overnight changes to bike position, gear, etc, usually result in unpleasant and untimely disasters. So before I (being part of the majority of racers probably not able to achieve true mid-foot cleat position) run downstairs and slam my cleats into the back seat can one of your noted authorities please comment on this hybrid cleat positioning?

I am not totally clear on which is which; memory fails me, but the version with the one piece carbon sole is more rigid than the version with the bolt in insert type carbon sole. Neither are as rigid as many other brands of carbon shoe sole. Sidi resisted carbon soles for years believing that there was such a thing as too much stiffness in a shoe sole. Now that they have carbon soles to fight marketing wars, theirs are not as rigid as many competitors.

I stoped riding for 2 weeks as the winter was rainy and cold and then I got sick with the flu, but since about 3 months ago I got back to my usual mileage, but I am getting slower and slower every week, feeling a lot more tired than usual. I have been getting muscular soreness and pain in my legs the day after a ride for the last month or so, with no other explanation about my health, except for an acid reflux syndrome which I do not think is related to this. A recent physical examination returned a negative result and my weight is normal. Any ideas?

This sounds like a very frustrating situation, with several possible causes, medical and non-medical. First I would consider nutrition: are you getting enough carbohydrate to support the training you are doing? If you are maintaining weight and getting about 50% or more of your daily calories from carbohydrate, this is not your problem. If you are losing weight, or are maintaining on a low-carbohydrate diet, you should look into increasing your carbohydrate consumption. Could there be any other nutritional problems? Do you avoid salt for instance? That can lead to fatigue.

When riding the new cleat position feels quite comfortable and perhaps more efficient. However, after about 2hrs of riding my lower back (Quadratus lumborum?) becomes quite fatigued. In my previous cleat position and saddle height, lower back pain was never an issue, so this is surprising to me (Come to think of it, I made the same cleat and saddle height changes last year with my MTB and got the same back fatigue).

Anyway here are my questions: 1) When switching to a more arch oriented cleat position is lower back pain or fatigue common?
2) Or is this back fatigue only common to those with saddles too high for arch cleats?
3) Also, all my recent adjustments seem to have my saddle height in free fall (lower quads next to knees burning...drop the saddle, broken neck...drop the saddle, arch cleat...drop the saddle), are their any ques for when a saddle is too low (Back pain?).

I've stopped going to physio, but have carried on with the exercises and stretches. After a break from the bike in late fall, I started up again on my indoor trainer in January, still using the Specialized shoes. After gentle rides of 15-20 minutes, I developed knee pains around my kneecap, and my knee was a little sore the next day. I carried on like this for several weeks, and finally decided to ditch the wedge and go back to flat shoes.

I was looking around the internet the other day looking for some suggestions on stretching routines. Some of the articles I found though (including Wikipedia), were claiming that stretching actually decreases athletic performance and does not contribute to injury prevention. I've always practiced before and after workout stretching routines as well as incorporating yoga into my weekly training. Could you please explain where these claims stem from and suggest an optimal routine?

Thanks for the awesome question. This is a very controversial topic and here's my best effort to cut through the controversy and provide a balanced view. The evidence that higher levels of flexibility impair certain sorts of exercise performance (especially running and jumping sorts of exercises, and repetitive motion exercises like cycling and running) is incontrovertible. The absence of evidence for stretching preventing injury is pretty convincing too, but some people swear they have to stretch to keep their back or knees functional. What's going on?

The truth is that there is no one correct program for all. Ideally, we would all have a very individualized system of stretching and stability based on our specific needs. In general, I don't prescribe stretching as a short term performance enhancer. Flexibility is of value for those individual who have restrictions preventing them from attaining correct alignment due to soft tissue and joint restrictions. Often I have seen bike fitters adapt the bike to someone's pathology rather than correct the pathology (or guide them to someone who can correct it), usually because they do not recognize normal from aberrant motion patterns.

If we examine the available research, there is no compelling evidence to support either the ergogenic or detrimental effects of stretching on exercise performance, and apparently none that directly examine endurance performance -- which is what's relevant when talking about cycling & road racing. Of the available research on the topic of stretching and exercise/strength performance, the evidence is divided. There are a few published studies that have looked at stretching and its effects on explosive muscular efforts or strength endurance (typically measured as maximum # of repetitions of a strength exercise such as a leg press at a percentage of 1 repetition max. weight), but as mentioned, the results are mixed.

I am 6'1" 160, and I prefer to ride 700x20's because of the lower rolling resistance. I feel there is less drag on the rear end. I live in an area where it is not highly technical in terms of downhills and constant turns so I have not had a problem with grip. I have had the back end come loose on up hill sprints, but that seems to be a problem for some of my friends to who run 23's. However, they do think I am crazy for running super thin tires. What do the pros do in dry conditions (non pave')? Any recommendations?
