Just some of the results and improvements from people within Addiscombe CC that i've helped cyclists faster/ more comfortable/more powerful/ less pain/more efficient and generally just feeling better on the bike. Efficiency drills included with bike fit.
Rider 1 25% more efficient lower average heart rate, higher power, higher average speed
Rider 2 30 watts more at TT speed feels more aero, and a lot more comfortable and smoother
Rider 3 1km faster with no effort 20% improvement in efficiency
Rider 4 15% initial improvement in efficiency forefoot tilt corrected feels more planted and powerful with pedals
Rider 5 leg length discrepancy corrected with wedges and forefoot tilt corrected now says is flying and winning for 1st time
Rider 6 20% improvement in efficiency knee pain gone, forefoot tilt corrected and more power
Take advantage of the special offer for Addiscombe members of £50 for a 2 hour bike fit, which runs out in 2 weeks, then going up to £100. (Wedges additional at £3 each dependent on how many needed after checking for forefoot tilt and leg length discrepancy)
The SpinScan Pedal Stroke Analyzer that helps you increase power and efficiency by up to 25%. The multicolor torque graph represents one full 360 revolution divided into 15 segments. The left /right leg percentage power splits give you the feedback needed to pedal in "circles". It will identify "flat" or "dead" spots in the pedal stoke where optimal power is not transferred to the drive train. A dynamic bike fit utilyzing SpinScan is an excellent way to take the subjectivity and guesswork out of the bike fit process. We also look at cleat positioning, forefoot tilt, lateral and medial knee tracking, and use wedges to correct leg length discrepancies which balance out the pedal stroke and enable more power to be transferred from rider to the pedals equalling faster speeds and race times.
Experience has shown that after an initial pedal stroke evaluation with the SpinScan, most people can improve their pedaling efficiency by as much as 20-25% in their first session alone simply by making improvements to bike position. Once in the optimal position, additional gains of 10-15% are possible using the feedback from SpinScan while riding courses and doing drills that address the weak areas of the pedal stroke. For example, by simply concentrating on "wiping gum off the bottom of your shoe" at bottom dead center will result in an increase in torque. Does this improvement in pedaling mechanics actually translate into improved performance on the road where it counts?
BIKEFIT SYSTEM WEDGES AND Sound Coaching
‘Since riding with the wedges my pedal stroke is more powerful, driving the bike forward. I really believe that I will be using the Wedges for the rest of my cycling career; the benefits are so big for what is such a simple but very effective piece of equipment'.
Nicole Cooke - Olympic Gold Medalist 2008
So if you have any of the following?:
* Knee pain?
* Lower back pain and hip pain?
* Leg length discrepancy?
* Illiotibial band tightness and lateral knee pain?
* Do you pronate?
* Tightly clenched toes and/or aching on the outside of your feet during rides?
* Feet hot spots?
* Flat feet?
* Lack of power?
* Excessive movement of one or both legs while pedalling?
* One foot that never feels quite right in the shoe/pedal?
* One good leg, one not so good?
and you want to know how to go faster, have more power, become more efficient, have less pain in your back, knees hips etc, aches or niggles, or numbness in your feet win your next race, get a PB, or your CAT ? licence then you can contact me either by PM, email me at dynamicmotion1@hotmail.com, or call me on 07958635142, or speak to me when you see me....

ok so the addiscombe special offer i've been running for the last 6 weeks runs out today, but wait for it, for the next 4 weeks i'm going to be offering 25% off for addiscombe members only. so thats £75. if you have friends in other clubs (why would they?) then please let them know that i'm doinbg the dynamic bike fits at geoffrey butler cycles now aswell.
How did Lance Armstrong improve his pedalling efficiency by 10% and an 18% improvement in steady state power per kilogram body weight to become a 7 time Tour de France Champion?
This case describes the physiological maturation from ages 21 to 28 yr of the bicyclist who has now become the six-time consecutive Grand Champion of the Tour de France, at ages 27–32 yr. Maximal oxygen uptake (O2 max) in the trained state remained at ~6 l/min, lean body weight remained at ~70 kg, and maximal heart rate declined from 207 to 200 beats/min. Blood lactate threshold was typical of competitive cyclists in that it occurred at 76–85% O2 max, yet maximal blood lactate concentration was remarkably low in the trained state. It appears that an 8% improvement in muscular efficiency and thus power production when cycling at a given oxygen uptake (O2) is the characteristic that improved most as this athlete matured from ages 21 to 28 yr. It is noteworthy that at age 25 yr, this champion developed advanced cancer, requiring surgeries and chemotherapy. During the months leading up to each of his Tour de France victories, he reduced body weight and body fat by 4–7 kg (i.e., ~7%). Therefore, over the 7-yr period, an improvement in muscular efficiency and reduced body fat contributed equally to a remarkable 18% improvement in his steady-state power per kilogram body weight when cycling at a given O2 (e.g., 5 l/min). It is hypothesized that the improved muscular efficiency probably reflects changes in muscle myosin type stimulated from years of training intensely for 3–6 h on most days.
COMMENT: This study looks at Tour de France Lance Armstong and physiological changes that occurred over the years leading to his first TDF win. This is a most interesting article looking at the physiologic changes that occurred to Lance Armstrong over a seven year period, to the point of becoming the dominant cyclist in the world. The most interesting finding is the only substantial change is he improved his cycling efficiency of just under 10%. When combined with his reduced body weight this resulted in an 18% improvement in steady state power per kilogram body weight. We believe that change alone, when applied to someone who is already at world class level, can explain his dominance in the Tour de France that occurred at the end of this period without the need to invoke any performance enhancing drug use (drugs cannot cause such changes). Unfortunately, despite Coyle recognizing this huge finding Coyle only has a mediocre analysis as to how one might improved pedaling efficiency so substantially. Coyle simply assumes this improvement came about because Lance somehow changed his muscle fibre type to more slow twitch muscles without any discussion as to other potential methods (see the Luttrell study above). Regardless of how Lance managed to improve his efficiency, it is important to understand that improving cycling efficiency can improve performance IN EVERYONE! As clearly demonstrated in the Luttrell study above, PowerCranks can improve cycling efficiency in trained cyclists.
He became more efficient in what he was doing, ie pedalling in circles.
Unless you are riding a bicycle simply for the joy and exercise you probably care about how fast you are going. The speed you ride depends upon the power your muscles can generate and then how much of that power you can transmit to the road. Your speed is then determined when this power equals the forces generated by friction, rolling and air resistance. Aerodynamics has a much smaller effect on overall speed than power delivered to the real wheel, unless you are going very fast. There is little benefit to having a perfect aerodynamic shape if you cannot transmit much power to the road. The difference between the power generated and the power delivered to the road is pedaling efficiency. How much power your muscles can generate is primarily determined by muscle size and how many are being used. How long you can generate any given power is primarily determined by blood flow to the muscles.
The Problem
Everyone knows it is more efficient to pedal as shown in Figure 2 than Figure 1. Didn’t you expect to pedal like Figure 2 after you bought clipless pedals? But, studies have shown even professional cyclists, most of the time, still pedal as shown in Figure 1, contributing negative torque during the recovery portion of the pedaling movement. (See: Whitt and Wilson, Bicycling Science, The MIT Press 1995, p. 63)
So you might ask, “Why do I pedal in this inefficient manner, even though I have clipless pedals and know better?†The answer derives from how all of us learned to pedal as children.
Since our first tricycle, we have always pedaled using conventional cranks with crank arms fixed 180? apart – and, until we became serious about cycling as a sport, we were never attached to the pedals. Therefore, our nervous system learned that “proper†and “efficient†pedaling technique involves keeping a small amount of back pressure on the pedal during the recovery, in order to facilitate rapid application of power on the down stroke. This is the most efficient pedaling dynamic if one is not attached to the pedals! By age 7 or 8 your nervous system could pedal in this “most efficient†manner without thinking and you continued to reinforce this motion for many years. But, when you eventually “graduated†to clipless pedals, did you insure that your brain understood it had to relearn basic pedaling technique? Of course not! So your pedaling dynamic never changed. If it were possible to correct this poor pedaling dynamic by previously available training techniques the pros would have figured out how a long time ago, but they have not!
What Training Does
As soon as a body sees a stress beyond what it is used to it will begin adaptation to be better prepared to respond to similar stresses in the future. If the stress is not regularly repeated this adaptation will not eventually occur, but if the stress is regularly repeated, the body will eventually adapt. So, when we train the cells adapt to improve aerobic muscle functioning by increasing the concentration of the necessary cell proteins (including the number of mitochondria and contractile elements, meaning we get stronger and develop more endurance capability) and improving the ability of the body to provide oxygen and sugar to the cell by developing improved heart function and blood flow to the muscle (necessary for improved endurance). The sum total of these capacities when measured is called the aerobic capacity. Training improves our aerobic capacity.
Although training can increase the capacity of our muscles to do work, as mentioned above, the overall measured muscle energy efficiency can never be more than about 50%, even in trained individuals. Overall pedaling efficiencies of bicyclists are measured to be, generally, 16-22%. The primary accounting for this discrepancy is inefficiencies associated with the direction the muscle contractile force is applied to the pedal. We intuitively know how to improve this efficiency because we know it is better to --pedal in circles (as shown in Figure 2) as opposed to Figure 1? Isn't that why you spent good money on fancy (and sometime expensive) shoes and clipless pedals? But, even though you purchased and use toe clips or clipless pedals, so you can pedal in circles (as shown in Figure 2) studies have consistently shown that even professional cyclists pedal as shown in Figure 1, contributing negative torque during the recovery portion of the pedaling movement (from Bicycling Science, The MIT Press, 1995, p. 63).
Now this may seem like a lot of technical information, but the essence of it is, that if you become more efficient you become a faster cyclist. Thats it! Just look at Lance!

Nick,
You know we had that little conversation about pedal efficiency, well I have been thinking about it a bit more and thinking back to some tests that a guy did a while ago from Kingston Uni on cadence and its effect. I actually think that cadence/pedal efficiency is not actually that important.
If you have a poor aerobic system but good strong legs, then it may actually be better to just crunch bigger gears. I kind of think about Jan Ulrich, he may not have been as successful as Lance, but Ulrich level is good enough for me. I think it depends on the rider and their physiological make up as to whether faster cadence and more efficient pedalling is worth it.
For example, if you have trained yourself and naturally have strong quads, then pushing down hard and recovering on the upstroke is going to be better than going through the whole pedal revolution concentrating on keeping equal power and just finding yourself getting tired legs from riding around the whole stroke and not going any faster.
So, here is an example of training for those that don't want to ride with the whole pedal stroke. Whack the bike in a huge gear and stomp like a crazy man. Keep doing this until you cannot turn the pedals. Do this every time you get on your bike and soon you will be stomping harder than everyone else and will be winning.
This advice is given from Crankwarping Training(c). Feel free to pm me for any further useful crankwarping tips.
Cheers

this includes cleat setup getting them in line, which can depend on the arch of your shoes, (some are higher now) the curve of the shoe or whether it goes straight back, also looking at forefoot tilt with a special measuring tool which most bike shops don't check (like checking for pronation in running), any leg length discrepancy (muscular or structural). i then look to correct the forefoot tilt to support the show in its natural position once i have calculated the degree of tilt and therefore i can add the required number of wedges to the shoe pedal interface.
have a look at my website for more info at www.sound-coaching.co.uk or pm or call me on 07958635142 if you want. i can now do bike fitting at GB Cycles if you prefer that
i also teach people how to pedal more efficiently, ie produce even pressure all the way around the pedal stroke, and give drills for people to practice, as this takes time to re learn muscle firing and movement patterns. all this is done on the computrainer measuring efficiency, power split, torque, power and speed so that i can see the difference and improvements during the session. generally i see speed gains of 1-2 mph and efficiency gains or 20-25% which with consistent practice of my efficiency drills means this becomes your natural riding style
prob bit more info than you asked for, but better to give you the full picture of what i do, i'm a personal trainer and sports therapist, the only uk registered racermate computrainer coach and level 3 british triathlon coach aswell

As Marco pointed out Coyle's work has been crticised for errors.
Here's a research project that was shown to me based on a 6 years time period looking at the influence of cycling efficency with one of the top Australian cyclists. The study was done during 1995-2001.
Conclusuion of study :-
"This data do not support the hypothesis that years of heavy training improve cycling efficiency. VO2 max and corresponding power output in this champion cyclist where exceptionally when expressed per kg body mass. However, measures of cycling efficiency were not unique. Accurate data describing how Phsyiological characteristics respond to years of training in elite athletes are difficult to obtain and need to be interpreted with caution because of the challanges of maintaining calibrated equipment..

Nick, a question for you. Is the improvement you see down to your subjects just generally training more once they come to you, or is it the same amount of training they were doing before just now they are doing the efficiency drills they are going faster? Is it the drills or is it time on the bike training?
Cheers

Nick,
How many power cranks have you sold?
How many have been returned after the 90-day money-back return policy expires?
Do you use the power cranks yourself?
Have you personally witnessed "Improve your efficiency by 20% and speed by 2-3 mph in 6 months"?
What sort of physiological testing are you offering to determine a customer has a neuromuscular limitation?
Cheers Rob
