Having the Best of Both Worlds (Gearing)

Posted on Jul 15, 2015

OPTIMAL ROAD GEARING (for the rest of us) BACKGROUND Shimano’s latest Ultegra FC-6800 and Dura-Ace FC-9000 cranksets offer combinations not available by any other manufacturer. Shimano’s 4-arm pattern is designed so that there is no need for separate 110BCD and 130BCD cranksets. WHAT IS BCD? – BCD, or Bolt Circle Diameter is the diameter of the circle formed by the stack bolts. Stack bolts are the small bolts that hold the chainrings to the spider of a crank. In the past, most bikes came with full-size/standard gearing, mostly 53/39 chainrings. In order to support these larger rings, a 130mm BCD bolt pattern was used. The problem was that if 53/39 gearing was too big for you, the only option was to go out and buy another crankset, a 110BCD with 50/34 chainrings. This was called a ‘compact’ crankset. Shimano did away with all of this nonsense by redesigning their latest 6800 and 9000 cranksets to take ANY of their gearing, meaning, buy 1 crank set and you can easily interchange virtually any chain rings to achieve your needs. I say virtually since Shimano recommends a 16Tooth maximum difference between the large...

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...

In case you were wondering … Gear Numbers

Posted on Jan 17, 2015

This can be viewed as a TECH NOTE for the cycle computer manufacturers as well as the GPS manufacturers. Last week I was testing several different GPS head units and cycle computers that ‘talk to’ Di2. But, after comparing the data, I noticed that something just wasn’t right. But let me take a step back. The Shimano D-fly wireless transmitter sends several pieces of data to ANT+ devices. These data of importance being Di2 battery level and gear position (front gear number, rear gear number). Its up to the cycle computer/GPS to take this data and display it in a value added format such as a graphical representation of what gears you are currently in and by recording time stamps, can tell the cyclist what % of the ride he/she was in what gear. So what’s the issue? After entering (a) Cassette Model 9/10/11, (b) Cassette type (11-23, 11-25, 11-28, etc.),  and (c) Crankset Type (50-34, 53-39, etc.) into your cycle computer/GPS, it has enough information to display all kinds of data for you. And that’s the issue. In this example,...

2014 Products of the Year

Posted on Jan 14, 2015

For the 2014 Product of the Year Awards, I have added the categories of  HARDWARE, SOFTWARE, CLOTHING and HONORABLE MENTION. This was actually pretty tough to put together since every product I have tested has been top-notch from every manufacturer. Not a dud in the group. Every product I tested lived up to its manufacturers spec-sheet and every product performed extremely well and met/exceeded its intended purpose. For 2014, each manufacturer put a lot of quality back into their products and every manufacturer I have spoken with has up front and honest when answering any and all of my questions. Therefore, this made it extremely difficult to pick the best of the best. What I decided to do is create a THEME for 2014 … ELECTRONICS. Since Di2 has been out for awhile, I looked at what’s next. I decided to look at the ‘accessories’ built to support Di2. So here goes; HARDWARE – In keeping with the 2014 theme, I chose the Shimano d-fly SM-EWWO1 wireless transmitter. This small transmitter adds a whole new dimension to Di2 by transmitting Di2 data such as % battery remaining, current gear...

Cyckit’s Aeroclam Hard Shelled Saddle Bag

Posted on Jan 7, 2015

INTRODUCTION CYCKIT Ltd, located in New Zealand, specializes in designing and producing integrated bicycling storage products which are targeted primarily for higher end users in the road bike market. Cyckit’s initial goal was to create a highly effective saddle bag without using Velcro and zippers which are two issues I have had with cloth saddle bags. The cloth tends to fray, the Velcro wears out causing the bag to either hang down or fall off completely and zippers get stuck the first time they get dirty, which is the worst thing that can happen as it prevents  you from getting to your spare tube and C02. Cyckit’s founder, Pat Reardon, looked at the problems with current saddle bags and decided that there had to be a better way. After interviewing 125 road cyclists, common problems, issues and enhancement requests became evident. These being that the bag had to be completely secured under the saddle, seamless integration to the saddle (i.e., more aerodynamic), easy access to the contents, must fit most saddles and free of contact with the cyclist while...

STRAVA incorrectly calculating total elevation/altitude...

Posted on Dec 10, 2014

Recent issue with Strava. Meaning … DON’T BELIEVE THE ALTITUDE DATA IN STRAVA. I did a local course this morning. The Magellan Cyclo 505 stated 4,080.56 feet of climbing. When I uploaded this ride to Strava, Strava said 6,918 feet. How can these be so different? The Magellan Cyclo GPS creates a GPX file and every second builds on this file as you ride, updating each parameter including Lat, Lon, elev, hr, power, etc. After the ride, when you hit STOP, the cyclo ends the recording, calculates the totals and closes the file – that’s why it takes several seconds for the Cyclo 505 to respond after you hit STOP. At home, you can upload this file to your local Magellan account where a graphical representation of the ride is displayed. Regarding Altitude, the Magellan adds all of the waypoints up and, for this ride was calculated to be 4,080.56 feet. I then uploaded to Strava and now the total Ascent is 6,918 feet. So where is the discrepancy? I then took the GPX file and changed each <ele> to <xxx>...

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...
