How Can I Get Better At HILLS?

Posted on Jun 7, 2016

The most common question that I get is “how can I get better at doing hills?” The answer to this is in 3 parts; 1) Change your gearing CASSETTE: Probably the easiest of the ‘big-3’ to implement, especially with Shimano’s new 68xx and 90xx derailleurs that can handle larger cassette gears right out of the box. For larger gearing, the CS-6800 offers several viable options, 11-28T, 14-28T and 11-32T. Since the CS-9000 includes several sprockets made from titanium, it is considered a racing cassette, therefore, it has fewer options. 11-28T and 12-28T are its largest offerings. I recommend the Ultegra CS-6800 as the best price/performance. 11-28T: 11-12-13-14-15-17-19-21-23-25-28 (my configuration) PROs: Gives a good spread in gearing. 11T for go fast and 28T for climbing CONs: From 15 to 25, there is a 2 gear jump and from 25 to 28 there is a 3 gear jump.   14-28T: 14-15-16-17-18-19-20-21-23-25-28 PROs: Also known as junior gearing which makes it USAC legal for juniors who run a 52 front chainring. Gives the tightest group of gearing. CONs: From 21 to 25...

Correct Pedal Stroke? The Efficient Biomechanics of Pedaling...

Posted on May 9, 2016

A REVIEW OF WHAT’S THE CORRECT PEDAL STROKE? From time to time, we have to step back from our daily habits and analyze one thing – in this case, it’s all about pedaling. On the surface, it seems pretty basic, just turn the cranks around with your legs, push as hard as you can for as long as you can. Deep diving into this simple issue brings many complexities. Knowing how these complexities work hand-in-hand with each other can actually make you faster on the bicycle by being more efficient. So let’s get started; Ric H is concerned about his pedal stroke, leg alignments and foot position and writes; “I’ve noticed over the 14 years that I’ve been riding a road bike that I’ve changed the alignment of my legs from splayed out to in toward the top tube and my feet from heels up to heels down. Please take some time to explain the advantages of certain leg alignments and foot positions and how this impacts my pedal stroke.”   A good bike fit is essential! First off,...

WHAT CAN YOU TELL ME ABOUT ROTOR (Q / QXL) RINGS?

Posted on Apr 29, 2016

As a Bike Fitter and USA Cycling Coach, one thing I get asked all of the time is “what can you tell me about ROTOR Q-Rings and will they work for me?” The short answer is yes. Q-Rings will work for most people, but, there are several exceptions which I will go over later. For those that don’t know what a ROTOR Q-Ring is, it is an elliptical chainring that helps increase your performance by varying drive-train resistance during pedaling. ROTOR’s elliptical rings maximize the strong muscles and minimize resistance during the weaker part of the pedal stroke. During one complete revolution of the crank, the cyclist experiences 2 ‘dead spots’. One is located at top-dead-center (TDC), the other at bottom-dead-center (BDC). This occurs at these 2 spots because you are not pushing anymore on the down stroke leg but not yet pulling up for the up stroke. In other words, these 2 points in the pedal stroke are where you are transitioning from pulling to pushing muscles on the ‘upper leg’, and transitioning from pushing to pulling muscles...

A Look Inside a “Made In The USA” Bearing...

Posted on Sep 1, 2015

A Look Inside a ‘Made In the USA’ The Parts Shoppe (TPS) 6806 Bicycle BB30 Bottom Bracket Bearing As an engineer by trade, I am always looking at best ways to make the bicycle faster. It took about a year, but I was eventually able to find a Chinese bearing manufacturer who produces fairly decent hybrid-ceramic bearings. Most Chinese companies who claim to be manufacturers are actually just distributors. That’s one of the reasons it took so long to find an actual manufacturer making quality products. But, as I found out, the one drawback was that hybrid-ceramic bearings are quite a bit more expensive than their all-steel counterparts. I filed the following question in the back of my mind to address later -> “Is there a less expensive steel bearing at the same or better quality than these hybrid-ceramic bearings?” I ordered several sets of their hybrid-ceramic bearings and started testing. The bearings ran great – though it took them quite a while to settle in as well as they wore out after 1 season – about 10,000 miles. Still...

Female Cyclists ‘In’s and Out’s’...

Posted on Jan 21, 2015

Or, What’s the Best Saddle-type for a Female Cyclist? Reprinted from Cobbcycling.com The quest for a comfortable bike seat has probably been going on since the second day the bicycle was invented. It is the search for the Holy Grail, the quest for the answers to the Universe, the only thing stopping World Peace, it is on every person’s mind that straddles a bicycle. How can something as enjoyable as riding a bicycle, bring so much discomfort and still be overlooked or just accepted as being okay for that situation. For men, there seems to be a tendency to just “suck it up”, more miles will make it better and to just ride through the pain. Men have certain body parts that require different types of arranging to find comfort without getting crushed, women have a completely different set of issues. For women, the concept of suffering through it, is not that pleasurable, the thought of hours in the saddle has kept many women away from the sport. As a saddle manufacturer, we get many e-mails and phone calls...
