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...

SBG-32 Bike Grease

Posted on Apr 29, 2013

For the past several years, I have been researching and testing greases for use in re-building/re-lubing bike bearings, lubricating cables, nuts & bolts. Below is a recent write up that I completed for an on-line bicycle testing/product evaluation newsletter that discusses this grease as well its testing. To summarize, this specially formulated grease performs so well that I recently received a reply from Wayne Stetina (Shimano) as to how this grease performs. Even though he cannot officially endorse this product without Shimano Japan certifying and authorizing this grease, he does mention that he prefers it in his own wheels. This seems to be the thinnest grease you can get before it turns to oil.  But that doesn’t seem to negatively impact durability.  I have personally inspected Rick’s wheels & can confirm what he tells you about his mileage & wear test results.  I can’t personally or officially endorse it before I get approval from Shimano Japan, however I do prefer riding it in my own DA wheels, & have not experienced any wear related failures with this grease or...

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...

A Low Cost Laundry Detergent Mixture that Really Gets the Smell Out of Athletic Clothes!!...

Posted on Apr 10, 2013

WHATS IN THE PACKAGE(S): I have been looking for a cost effective solution that will actually work to clean our families bicycle clothes. While in high school, my daughter was in cross country and came home with some foul smelling clothes. Using a powder instead of a liquid is what her coach recommended, but, the clothes were still not 100% fresh. One day, just for the heck of it,  I added some baking soda (equal amount) and this seemed to be the boost that the detergent needed. I have been using this formula for over a year now and this mixture has not had any adverse reaction with the cycling clothes. Clothes now come out of the washer smelling fresh and clean.         +     COST: Energy efficient washing machines recommend using the lower line of the scoop. By doing this, I am getting 80 washes from the Laundry Detergent. The 13.5 pounds of baking soda is good for 200 loads. Combining these, I can do a full load of sports clothes for less than 10...

Up to the top of Haleakala and back…Your how-to guide...

Posted on Apr 8, 2013

Up to the top of Haleakala and back… by Rick Schultz Several years ago, my wife, daughter and I traveled to Maui for a fun-filled family vacation. My wife and daughter wanted to take one of Maui’s famous bicycle tours from the top of Haleakala volcano back down the road to the bicycle shop 37 miles away – yes, basically it’s a 37 mile downhill ride. This sounded like a great outing with the family, but seemed a little too easy, so I opted to do the ride both ways – up the 10,023 foot volcano and back down! My wife and daughter would ride in the tour van and meet me at the top so I could ride down with them on their downhill excursion. Here’s the official Haleakala webcam – http://www.ifa.hawaii.edu/haleakalanew/webcams.shtml BACKGROUND: I have often been asked, “how would you rate this ride?” I always tell people that Haleakala is a good ride, but you need to be in shape. Several people I know have attempted it, but turned around at the park entrance which is still...
