This made me think. If say for instance I am riding a 54cm Cervelo Soloist, I run a 120 mm stem. I have noticed that I have toe overlap on the front wheel when turning sharply, this has never been a problem in a race situation, only in slow speed maneuvers. I feel sometimes that a larger frame may be something that would work for me. I know this is vague, because I do not have any measurements to give you. I have been told that my legs are long as well as my arms for my size. I am 5'-8.5" tall, my inseam is 32in, and I weigh 145 lbs.

You are right. 30+ years ago, larger frames for a given rider than they would ride today were common. Riders had less gears to play with too, so pedaling fast for extended periods was more valued than it is now. This meant that seat tube angles were often (not always) steeper on many frames of the 70's than they are now. Leather seats of the era had much shorter seat rails than modern seats which steepened the effective seat tube angle by a degree typically. The net effect of all of this was that riders rode further forward generally.

I'm a male 54 year old, 185 lb avid recreational cyclist who logs about 3500 miles a year and does the typical circuit of charity metrics and centuries throughout the year including a lot of hill work. My wife and I also take cycling vacations with companies like Backroads and Trek Travel and have a trip planned this summer in the Santa Fe area where we'll be riding for a week at altitudes of between 7000 and 9100 feet.

Now, I wasn't using two HRMs at the same time, but I know from several years experience with the Polar, that I probably would have had a calorie expenditure of about 1800. I am a 59 year old male, 5 ft. 11 inches, and on both units I entered my actual max heart rate (177) derived from a stationary bike protocol. I am an experienced road rider. I inquired with Garmin's tech support about their Kcal calculations, and they simply responded that their formula was "proprietary."

I have two questions. What factors are typically included in the Kcal formulas used by HRMs? Do these formulas vary between manufacturers? With the discrepancy between the 2 units with which I've had experience, the question of accuracy of the Kcal estimates comes up. I always knew these were estimates, basically ball park figures, but with this recent experience, I almost wonder if these figures are garbage.

I am a 35 year old club racer with over 15 years of riding under my belt. On and off over the past four years I have had a problem with numb feet. I switched from Sidi's to Specialized Carbon Pro's to no avail. My bike, clothing fit is correct and I do not need orthodicts. Usually, after and hour and half of in the saddle riding results in my feet going numb, nothing else. No one as yet has been able to help me. Any suggestions?

I am having problems getting my cleat positioning correct, and I think it has to do with an anatomical problem. No matter what I seem to do, my right heel always wants to point outward, and my left heel always wants to point more inward (basically angling my legs to the left). I am uncomfortable unless they are angled about a half centimeter this way. As far as I know I don't have a leg length discrepancy, but my chiropractor feels that the pelvis is slightly rotated.

He measured me up, went ahead and built me the bike and I've been running it since. Just recently I wanted another road bike and went to see John Kennedy. He measured me up and came up with these dimensions: Seat tube length: 59 (centre to centre); top tube length: 58 (centre to centre); seat tube angle: 71 degrees; crank length: 175 mm; handlebar width: 44 mm; stem length: 110mm; handlebar drop: 14cm.

I'll let Steve give you the super duper Steve detailed answer, but here's what I thought as I read your note just based on the dimensions and before I read the lines that follow, and I quote myself here, "If he liked the old bike he's not going to like the new bike unless he's gained a bunch of weight. If he has gained a bunch of weight and liked the old bike, he's going to like the new bike more".

I can't answer your question in the way you would probably like me to as I know nothing about you other than what you have told me. What I can say is this: If you are in any doubt about buying a bike to the newer set of dimensions, have John Kennedy set your existing bike up in the position he intends you to be in and ride around in that position for long enough to be able to make a decision based on your own experience.
