Mechanical vs Electric Shifting vs Aero

Posted on Oct 15, 2013

  The group of cyclists that can take the biggest advantages of this new technology are the triathletes. But, unless its a hilly course, how many times do you actually shift? For the road group, Shimano has added sprinters switches as well as climbers switches and, the way they are designed, you can add an almost unlimited number of switches. Let’s say for example you have a Cervelo S5. Getting the bike ready for an upcoming triathlon, you add aero bars to your S5. Running Di2, you can now add shift points to the end of the aero bars as well as shift from the road levers. You can even add a sprinters switch as well as a climbers switch to the bars. A truly versatile system. BUT, lets talk honestly about TT. Aero trumps everything else and to be honest, MOST time-trialers and triathletes would benefit far more from a bike fit AND using the correct sized components, than gain any advantage of using electric shifting. Most triathletes are so ill-fitted that their position in their aero bars...

Have the bicycling clothing manufacturers priced themselves out of the market?...

Posted on May 13, 2013

Your thoughts? Do you think the cycling clothing manufacturers have just about put their jerseys out of the reach of most people? Maybe that’s why I’m seeing more and more ‘Performance Bike’ jerseys on cyclists? email us or comment and let us...

Pet Peeve #1

WEARING TEAM KIT ARM WARMERS ON THE WRONG ARMS The thing that irks me and I tell guys all the time… “You are wearing your team kits arm warmers on the wrong arm. Inevitably, 1/2 of the cyclists out there have the warmers on the wrong arms so the sponsors name is upside down when riding. PEOPLE, CHECK YOUR ARM WARMERS for correct positioning of your sponsors...

Recovery Pulse vs Resting Pulse Rate

Posted on May 1, 2013

From Dr. Gabe Mirkin’s Fitness and Health E-Zine April 28, 2013 High Resting Heart Rate Increases Death Risk in Healthy People The Copenhagen Male Study followed the health of 3000 men for 16 years and found that the higher the resting heart rate, the more likely that person is to die (Heart, Apr 17, 2013). Those who had lower resting heart rates and did not exercise still lived longer than those who had higher resting heart rates, even if they exercised. The authors conclude: “This suggests that a high resting heart rate is not a mere marker of poor physical fitness, it is an independent risk factor for premature death.” The authors adjusted results for heart attack risk factors such as smoking, obesity and physical fitness. Compared to a resting heart rate of 50 beats per minute, a resting heart rate of • 71 to 80 beats/min was associated with a 50 percent increased risk of death during the study period, • 81 to 90 beats/min was associated with a 100 percent increased risk, and • over 90 beats/min...

Wheel Selection – A Point to Consider ?

Posted on Apr 29, 2013

I have discussed this with several of the hard-core Cervelo testers and riders and have come to the conclusion that Wheel selection is as important as frame selection. Meaning that I believe a given frame is designed with a specific wheel in mind. Here’s what happened. I have an R5ca and wore out a set of C24 wheels. I bought a set of C35’s for the bike, but the bike felt dead – felt like a piece of lead being pushed down the road. I seemed to have to labor more to spin the pedals. Went back to C24’s and the bike sprang back to life. It again feels light and very responsive. I could definitely feel a TREMENDOUS difference between these two wheels. I also have a Giant TCR Advanced SL that rides much better with C35’s than C24’s. My opinion is that C35’s are way too stiff for an already stiff (R5ca) frame, and the C35 wheels seemed to throw off the performance balance of the bike. But again, the Giant TCR Advanced SL loves the C35’s...

Points to consider before tire selection on frame with narrow stays....

Posted on Apr 26, 2013

First off, I am on my second set of tubeless tires. First set was the latest IRC Roadlite Tubeless. Will be doing a review writeup soon. Great tires, now am on Hutchinsons. Once you go tubeless, you dont want to go back. Tubeless ride softer and track better. Going back to a Clincher/tube combination, I found the ride harsh, jolty, bumpy, like riding on a rock. Tubeless are well worth the extra $$. If you don’t have a tubeless wheelset, don’t worry, Stan’s NoTubes has a Tubeless kit and others will be joining soon. Now, back to the issue at hand. Here’s something to think about when guessing if a tire will fit a frame with narrow stays. There is the initial measurement, as well as a ‘900’ mile measurement. Let me tell you what happened. R5ca with Dura Ace 9000 wheels – I have Hutchinson 700×23 Fusion 3 tubeless on the front. Hutchinson 700×25 tubeless Intense on the rear. Long story, but I am testing some tire combinations for a client. After 900 miles, here is what they...
