Best Location for EWW01 – Shimano D-fly wireless transmitter...

Posted on Nov 25, 2014

I’ve been experimenting with best location for the EWWo1. I have heard several people say that, depending on which GPS head unit you are running, there might not be enough signal strength for the head unit to read. Some cyclists have experienced timeouts with their head units and dropped/missing data when processing the results. Reading through Shimano’s tech docs for the EWW01, they imply that this location is a requirement. They seem very specific that the location needs to be mounted between 110mm and 130mm above the top of the right rear dropout. In actuality, this is only a recommendation for placement. Right rear seat stay mounting: The advantages are (1) easy access, (2) ease of connecting, (3) tucked in and out of the way. The disadvantage being that some GPS head units might not pick up its signal. So, where to mount it? This will work for both the older Ultegra 6770 SM-EW67A-E front junction (shown to the left) and the newer 3-port Shimano SM-EW90-A or the 5-port SM-EW90-B front junction (shown to the right). It’s just that the newer units are easier to work...

2014 Scattante RAZZO road helmet

Posted on Jul 21, 2014

        INITIAL OBSERVATIONS: I crashed several months ago. Hard enough to crush the rear section of my helmet. My old Scattante razzo helmet saved my life. Razzo is the lightest and coolest helmet in the Scattante lineup. It combines all of the looks, features, comfort and protection that the ‘BIG GUYS” offer at about 1/3 of the price. An added benefit is the integrated high-tech carbon reinforcement construction which holds the helmet together during an impact. This greater protection is the same feature as seen on only the most expensive helmets. Twenty-two (22) large vents provide considerable cooling while the foam material allows quick-drying of the pads. The razzo has a ‘wheel-type’ adjustable rear retention system for a custom and comfortable fit. Extremely soft nylon chin straps allow for easy adjustment but tended to slip and loosen a little during each ride. HOW DOES IT FIT? When riding a bicycle, the single most important thing you can do is to wear a helmet. The second most important thing you can do is to wear a helmet that fits you perfectly. Since...

The Best Tires I Have Ridden To Date

Posted on Jul 20, 2014

WHATS IN THE PACKAGE: Hutchinson categorizes the ATOM COMP as a “narrow profile clincher racing tire that excels on dry roads and pavements.” Hutchinson claims 4*’s (4 out of a total of 5) in efficiency, lightweight, puncture resistance and wear. So, after 1,200 miles, I agree with one exception, Wear & Longevity. The rear tire lasted 1,200 miles vs. 2,000 miles for a Hutchinson Fusion 3 Tubeless vs. 2,800 miles for a low cost Performance Forte Pro+ road tire. This is pretty poor mileage for a tire, so the bottom line is don’t use this as a training tire. This tire is for racing only. INSTALLATION OBSERVATIONS: I recently tested the Essor PACE 32mm Carbon Clincher wheels mounted onto a VeloVie Vitesse 500, and the Hutchinson ATOM COMP tires came included. Being that the wheels are carbon fiber, I mounted the tires by hand. This is because a friend of mine bought a set of Reynolds Attack carbon clincher wheels (pictured to the right) and took them to a bike shop to mount a set of racing tires. The...

THE LAST WORD ON CHAIN LUBRICATION I have been testing chains, lots of chains, lots of different companies chains to failure in real world conditions. Mostly, I have been testing how 11-speed chains work on 10-speed drive trains. Also, I started looking closely at lubes and the role they play in overall chain functionality. I have read numerous lubrication testing articles, what works, what doesn’t and why. This includes the infamous Velo News/Friction-Facts testing articles during 2013 where they concluded that a wax-based PTFE lube is best. Since PTFE will not stick to anything and nothing will stick to PTFE, Friction-Facts solves this by suspending the PTFE inside their wax (and Finish Line suspends PTFE inside their Dry Teflon® lube). In theory, Friction-Facts wax with PTFE makes for a great chain friction inhibitor … as long as the wax stays between the plates, pins and rollers. In real world conditions, this does not work as well as in the laboratory. In real world cycling, you are shifting the rear derailleur up and down the gears dozens and dozens of...

No More Junk Miles

Posted on Jun 6, 2014

Dr. Mirkin, Fitness, Health and Nutrition expert wrote an interesting article on thoughts about training. What works, what doesn’t, why he and his wife were getting slower using the accepted training paradigm. Dr. Mirkin always publishes news and views for the cyclist, runner and triathlete. A great source of information. I have reprinted it below, but link to article is attached to title below. Its short but informative. Have a read! No More Junk Miles June 01, 2014 by Gabe Mirkin, MD You can always continue to learn, no matter how old you are. I am 79 and Diana is 72. We like to ride a bike as fast as we can. I thought that I understood training, and we followed the rules we believed in, but our race times kept getting slower and slower. We know that to make muscles stronger, you have to damage them by exercising them against great force. That means your muscles have to burn at some point when you train. We know that to improve your ability to take in and use oxygen, you...

CRANK LENGTH – 2 Discussions

Posted on May 1, 2014

CRANK LENGTH DISCUSSION #1 – Damon Rinard, Cervelo Engineer Link to article I’ve heard many triathletes and time trialists are switching to shorter cranks: 170, 165, even 160mm. What do you recommend? CRANK LENGTH Great question. It is true that many top athletes are switching to shorter cranks for timed racing such as triathlon and TT. This is relatively new, because traditionally longer cranks were thought to be better since they give more leverage. However, crank length is just one lever in a drive train composed of a system of levers that transmit your foot’s force on the pedal to your tire’s thrust on the ground. The other levers in this system are the chain ring radius, cog radius and wheel radius. We vary two of these (chain ring and cog) at will whenever we shift gears. So we don’t need a small difference in crank length to change the leverage available to us. What does Dr. Martin say?   For many athletes, the idea “longer is better” has changed in part because of Dr. Jim Martin’s 2001 study...
