Optimize Lightweight Biking

Tony DuPont - Thursday, March 26, 2015
In a perfect world, we would all have a quiver of bikes hanging in the garage. Lightweight climber for when you’re headed to the hills. Aero road bike for long days on the flats. And a rig with wider tire clearance and subtly more relaxed geometry for those off-road adventures. For full story see...…/showdown-aero-bike-vs-light

Power Cordz Sponsors USA Ultra Triathlon

iO DuPont - Friday, October 25, 2013

Recently, we became a sponsor for the USA Ultra Triathlon. Over the course of a year, three events take place -- one in Florida (March), one in Oregon (July) and the other in Virginia (October). Steve Kirby, race organizer, has been managing the races since 2004 with the most recent one taking place at Lake Anna State Park in Virginia in 2013.

About USA Ultra Triathlon

USA Ultra Triathlon was born November 2004 when Steve Kirby took over ownership of the Virginia Double and Triple IRON Triathlon from Odyssey Adventure Racing. It was around a dinner table shared with our Race Doc, George Wortley, and other friends that helped as staff, that different names were bantered around and USA Ultra Triathlon was decided upon as that allowed us to promote the race across the country wherever we could find a suitable race course.

The world’s original Double IRON was in 1984 in Huntsville AL and was successfully hosted there from 1984 thru 2006.  The race was cancelled in 1997 because of logistics and a lack of volunteers.

Odyssey was formed in 1997 and was putting on its first set of ultra distance adventure races in 1998.  They acquired ownership of the Huntsville Double IRON, which fit nicely into their mix of races, holding the first one in Virginia Beach that year.  The Double IRON was moved to Colonial Beach, VA in 1999 and the Triple IRON was added as well.  Both events were held in Colonial Beach in 2000 before they were moved to Lake Anna State Park in 2001.

USA Ultra Triathlon has continued holding the events at Lake Anna since then, looking elsewhere to hold another Double IRON due to increase in demand.  Finally in March 2011 the first Double IRON was held in Tampa FL.

Steve Kirby started working with Odyssey Adventure Racing in 1998, while still on active duty in the Navy.  He retired after serving 26 years and worked full time for Odyssey; handling applications, website upkeep, awards, timing, and athlete point of contact for questions and information.  Steve left Odyssey in early 2004 to return back to school for another Bachelor’s Degree, Odyssey was sold at the end of 2004 and Steve acquired the Double and Triple IRON triathlons.

Thanks Kirby for asking us if we'd want to sponsor such a great event! Let the prepping begin for the next race/season.

Chinese Distributor Travels 1200 Miles with Power Cordz

iO DuPont - Monday, August 06, 2012
We love hearing ride stories, especially when Power Cordz are installed on the bike. One story we enjoyed hearing about is from our newest Chinese distributor, Hua Zheng, who rode his bike from his hometown in Chengdu, China to Tibet. Just to run the numbers for you, that's 2,000 km (more than 1200 miles)!! Pretty impressive, huh?


Hua Zheng, Power Cordz Chinese Distributor

We asked Zheng a couple questions to learn more about his adventure and here are his responses (translated from Chinese). Enjoy!

When did you ride from Chengdu to Tibet? 

From July 11 to August 5, 2009

Map of start and end points.

Did you ride alone? 
Yes, the entire journey. The majority of the time I didn’t see anybody riding a bicycle. It wasn’t until the last several days that I saw some people riding their bicycles. 

What kind of bike did you ride? 
I rode a 29-speed airborne titanium mountain bike. 

Did you have emergencies or exciting stories along the way? 
The entire ride was smooth, but I experienced some unexpected events and some interesting things along the way. 

I heard frequently in the Tibetan region that travel is not very safe, often there will be murder and robbery along the road. I was told to pay attention to safety, reach my destination before dark every day, and never travel on a dark road at night because it is relatively prone to accidents. Along the way, I met people who were very accommodating and friendly. It wasn’t as insecure as everyone said, as long as you had some self-protection, awareness and my own behavior – respect the local manners and customs. It was very good and the locals get along so it wasn’t unsafe. More interesting, while on the road I encountered a group of Tibetan on motorcycles. They asked me who I was, who I was with, where I was going or what I was doing. Whenever I would hear a motorcycle sound behind me, my heart would suddenly lift and I would start thinking about what this person would do and how I would summarize the answers to their questions. I ended up telling them that I went in front of my group and that my group was on their way. 

The performance of the bicycle went very well. It didn’t break down. I only broke a chain link and cut off a few luggage rack screws because my luggage rack was not set up for disc brakes. I needed to use very long screws and heavy baggage on the road. The screws broke in the screw holes. I had no way to take them out, but fortunately encountered a car repair shop and they had a hand drill to help me to remove the screws. Later, I added a few nuts on the screws so I didn’t have to worry about the fracture anymore.

In the sea of new road, I was constantly taking pictures of the scenery. The result was exciting. However, I didn’t have much confidence in the way I packed the camera. At one point, the camera pack rolled down the hillside into a lake. Inside my head I said “No” and quickly rushed downhill to find the camera bag. Luckily, the bag was floating on the lake. I opened it up and there wasn’t any water. I was pleased.  I was also thinking without camera, I’d have to go home immediately because there would be no camera to record the beauty I saw along the way. I would only go back to buy a camera and then would have to ride again. It was too painful. 

Tibetan Dogs
In Tibet there are too many dogs – big and fierce.  I was chased by a dog almost every day. I was besieged by three dogs in Qamdo. I was nipped in the thigh and the next day I went to the hospital had to get the rabies vaccine, which I was supposed to get three times, every other week. However, there were no longer big cities, just small town with hospitals but no vaccines. They assured me that every day dog bites occur and the dogs don’t have rabies. That is why the hospital didn’t have vaccines prepared. Later I returned to Chengdu to re-fill the vaccine. 

The weather change of the Tibetan region is very unique. Often you will experience spring, summer, fall and winter all in one day. I rode during the rainy season. It rained almost every day. One minute the sun was shining and then suddenly a cloud would appear and it would immediately start pouring rain. I would go through several sets of clothes every day. It was troublesome. It was depressing at times. I’d see a blue sky and white clouds in front of me and I’d hope I would be able to catch up to it but the clouds would turn dark and I’d immediately have to change clothes. 

Wrestling the Roads
Along the way, my ride was going well but that changed when a very serious accident occurred. I fell down the side of the road.  It was a flat, cement surface and downhill. I was speeding into a bend in the road which suddenly turned into gravel.  My front wheel immediately started slipping but I didn’t crush the brakes so I wouldn’t fly off and followed the bike into the fall. Bike and man hit the roadside barrier very hard. Fortunately, there was a fence there otherwise I would have flown directly down the hill. I laid on the ground for a long time, slowly recovering on the ground and I started check my body. There were no fractures or internal injuries. A closer examination revealed damaged clothes, hands and feet with a chunk of skin gone. The bike also had some wear and tear, but fortunately did not affect me to determination to ride. Even more fortunate, with such a serious crash, I was only slightly injured. I thanked God for if the car had gone over the fence there would have been certain death after the accident. Now every time I go downhill I’m very careful. 

How did you go get home? 
In Lhasa, I returned the bicycle home and then I took the train home. 

When are you going again? 
The plan is to ride a bicycle from Xinjiang in August-September 2012 and ride to Lhasa but I have a two-year-old son. I must get settled with him and then have time to go out. This year’s plan isn’t definite so I may have to go next year. 

How did you hear about Power Cordz? 
I know Xie Yi (a fellow Power Cordz employee), from a group of friends. He introduced me to Power Cordz. It was the first time I heard of the material. I was surprised, after seeing the cables. I thought that it truly was a revolutionary product. There were just too many advantages so I immediately put them on.

Here's a few more pictures from Zheng's trip.

iO DuPont cheers Boise cycling hero Kristin Armstrong on Olympic selection

iO DuPont - Monday, June 18, 2012

Boise held its collective breath when Kristin Armstrong’s front wheel slid out from beneath her on a slick spot in the first turn of the first day of the first ever Exergy Tour women’s cycling event. Some wondered if the resulting broken collarbone would upset Kristin’s resolve to earn a spot on the US Olympic team. But anyone who has seen Kristin Armstrong on or off the bike knew she was destined to ride in London later this summer. iO DuPont salutes Boise's top cycling star and wishes her further Olympic glory this August in London!

Armstrong is one of four women riders who will compete for the U.S. road team in London. It's the largest women's team ever to compete in the Olympic Games, as the maximum number of riders increased to four this year.

USA Cycling describes Armstrong this way: "The 2008 Olympic gold medalist, Armstrong proved to be one of the most dominant time trialists in the world in 2012, winning all eight international-caliber time trials she entered."

L.A. Times writer Diane Pucin describes Armstrong's Olympic seat as a comeback, after having a baby in 2010 and breaking her right collarbone just a few weeks ago in the opening stage of the Exergy 2012 tour here in Boise. But Armstrong was back at the race the next day, on the sidelines, but vowing to be back on her trainer within a few days time. 

USA cycling placed her on the road team based on her 2008 Olympic gold in Beijing and her stellar record since. She will also ride on the Olympic time trial team, along with Exergy tour No. 2 rider Amber Neben, of Irvine, Calif. (Specialized lululemon), based on her undefeated (8 for 8) record in trials.

Armstrong and Neben will ride with Exergy champ Evelyn Stevens of Acton, Mass (Specialized lululemon) and Shelly Olds of Gilroy, Calif. (AA in the road race.

The fact that the number one and two racers from Exergy, plus Armstrong, are riding on the Olympic team, adds even more cachet to the already highly lauded inaugural women's tour here in Southwest Idaho. The future is bright for women's cycling and Idaho, with Armstrong and Exergy, are sure to play a continued role in the sport.

Power Cordz Nosed Ferrules & E-Z Bend Adapters: Maximum Cord Protection

iO DuPont - Tuesday, June 12, 2012

Recently, Boise hosted the inaugural 2012 Exergy Tour and the Boise Ironman 70.3. The city came alive as athletes from all over the world descended on Southwest Idaho. Both races were pretty intense (weather, aside) and have easily become two of our top favorite highlights this Spring.

With the two events in town, we’ve been thinking more and more about making sure our bikes are ready to ride. In particular, we’ve been talking a lot about the interface between the housing and the bicycle, especially with some of the new brake levers coming on the market. So on that note, we’re going to take a few minutes and talk about our nosed ferrules and the new E-Z Bend adapters.

Bicycle ferrules act as end caps to the housing, ensure that the cable housing can't pull through the braze-on on the frame and prevent the Cordz from splitting or wearing. They also reinforce the housing, which can make it last longer. We’re all about safety at Power Cordz so when we saw the opportunity to provide a safer ride for our cyclists, we took the ferrule and modified it. One thing about the noses on our high grade, alloy ferrules that we think is pretty cool, is that the nose is designed to be shortened (by cutting to size), to reduce drag.

Pretty neat stuff, huh?

Now let’s say you want even more protection or if you have newer-style Campagnolo shifters or brake levers, our E-Z Bend adapter provides a protective liner so that your cables won’t be cut as they exit the brake lever or shifter. In addition, the E-Z Bend design is backward compatible to fit on all component sets. Before you order though, please check our compatibility page on our website to ensure the E-Z Bend adapters are needed (E-Z Bend adapters will only be included if they are needed to ensure proper connection). You may contact or call 208.908.0630 if you have additional questions regarding the E-Z Bend adapters.

We are pretty excited about this new addition to our Power Cordz Systems and we hope you will be, too!

So next time you’re installing a Power Cordz system, remember our nosed ferrules and E-Z Bend adapters are designed for ease of installation and give our riders the ability to customize their Power Cordz System to their frame to ensure maximum performance.

15 Year Old Ethan Reynolds Rocking Power Cordz

iO DuPont - Wednesday, May 16, 2012

Ethan Reynolds, 15, is at the bottom of his age class this season. But the rising star cyclist does not really mind because he's happy to help his 16-year-old teammates out for a year. It also helps that he's already beat adult pro riders in several races, racking up the junior and pro points.

"I really feel like I'm more of an all around rider, but crit results always come out better for me," Reynolds, 15, told us recently. Reynolds rides for the Boise Young Rider Development Squad, or BYRDS, based out of the Endurance Training and Fitness Center here in Boise, Idaho, just down the street from Power Cordz HQ. This is his fourth year racing—Reynolds won the 10-12 Nationals in Bend in criterium and the 13-14 criterium in Augusta, GA last year. More recently, he was the top junior racer in the circuit at Sea Otter in April.

Last year, in Georgia, Reynolds crashed and broke his frame two days before the big race. He replaced his old bike with a Gallium, a top-end racing bike from Argon 18, a Canadian bike maker. Reynolds outfitted the bike with a Shimano Pro bar and stem for a stiffer feel and outfitted the brakes with Power Cordz for a smoother feel.

Reynolds says that steel cables feel like they are pulling through the housing, whereas the Cordz are smoother, lighter, and win style points.

Future Bike Roundup No. 1

iO DuPont - Sunday, May 06, 2012

We just came across the photo below, from the February Paralympic Cycling World Championships in LA (via Bike Hugger), and are inaugurating a new blog series with it: The #FutureBike Roundup. In this space we will highlight the most cutting edge innovations in cycling technology. Obviously we are interested in futuristic bike materials here at Power Cordz, and this prosthetic leg, designed for a cyclist, is just the type of thing to kick off this blog series.

Hi-tech prosthetics are nothing new in the cycling world. Here is another version, with a dynamic, tension loaded pedal-foot interface, via Fast Company.

From Channel 4 in London, an interview with Chris Furber, head coach of the British paracycling team on the interface between bike, rider and prosthetic limb.

The New York Times recently profiled Cuban cyclist, Damian Lopez Alfonso, who is going to London for the 2012 Paralympic Games in August. Lopez Alfonso developed his own handlebar setup while training in Cuba, and used it as a fallback, when his state-of-the-art ride failed him in Guadalajara.

Find Power Cordz at the Sea Otter Classic

iO DuPont - Wednesday, April 18, 2012

The Power Cordz team is staying in Boise this week, enjoying beautiful, wet spring weather. But many of our friends are at the Volkswagen Sea Otter Classic in Monterey, California to participate in one of the largest bike expos in the world.

A fish-eye view of the 2011 Sea Otter village.

In support of all the bike people at Sea Otter this year, we set up a special discount code for attendees. To get the code, you have to visit our friends from the Boise Young Riders Development Squad (B.Y.R.D.S.) or from Core Concepts, a Boise-based, high tech/high style clothing maker, and pick up one of the glossy post cards we sent along with them. You will find a discount code on the card!

(Hint: The B.Y.R.D.S have booth #629, west of the Food Court, and Core Concepts is displaying their wares at booth #178 in the first Exhibitor Pod. Map here.)

The B.Y.R.D.S. are a premier youth cycling team based in Boise and they have some 25 riders in Monterey this week to race and gain critical exposure. We have been installing Cordz on their bikes for a few months now, so watch for these guys at the finish line!
