Tucson, AZ (April, 1, 2012): TriSports.com, the world’s premiere triathlon store, announces its patented new leg shaving technology known as Hybrid Shave Technology. After 2-years of research and development using wind tunnel, CFD and real world data, the engineers at TriSports.com have released their findings. Seton Claggett, who earned his Master’s in Hydrology from the College of Engineering at the University of Arizona, says “we have been using this proprietary shave method with our athletes for years but as we have grown as a company we know that for the betterment of the sport and in light of great customer service that we should reveal our research to the world.”
The Hybrid Shave Technology uses a scientific approach to removing leg hair on cyclists and triathletes to improve aerodynamics and speed. “The experiment,” says Tom Demerly, one of the chief investigators on the project, “was performed over many conditions and using many different shave patterns and what we found was that using basic aerodynamic principals of laminar boundary conditions coupled with muscle formation resulted in the ideal real-world power conversion on the bike.”
The final testing came down to analyzing the real world results of 1) Hairy Leading Edge Legs, 2) Full Shaved Legs, and 3) Short Stubble Leading Edge Legs (the Hybrid Shave Technology). Full hairy legs performed exponentially worse than the three chosen tests. The results are shown in the diagram above. “It was amazing how superior the performance was using the Hybrid Shave Technology”, said Claggett, “the power savings were staggering. It is amazing how basic aerodynamic principles such as using the Navier-Stokes equation and Reynolds numbers to estimate the boundary layer conditions of a hairy legs work in wind tunnel and real world testing.”
The results have shown an actual average power savings of 10 Watts over distances greater than 30k (compared to a full hairy leg and almost 6 Watts over a fully shaved leg). Over a 112 mile relatively flat course with little wind the TriSports Hybrid Shave Technology will save you about 6 minutes. “6 minutes”, says Claggett who used the Hybrid Shave Technology at the 2011 Ironman Arizona, “is a ton of free time, especially if you are trying to get to the finish line as fast as possible.” Claggett consequently won his age-group by a mere 45 seconds. “You can spend hundreds of dollars on an aero helmet, thousands of dollars on aero wheels and an aero bike, or you can use the TriSports Hybrid Shave Technology and get the same benefits – do everything and you are all-in.”

Conclusion: Hold off as long as you can during the season to get the training benefit of hairy legs and then shave them just before your “A” race. The results of the TirSports Hybrid Shave Technology speak for themselves, so when you do shave, use this method if you want to optimize aerodynamics.

There aren’t many products that I gush about, but I have found myself more than once in the past few months on the sales floor gushing to a customer about the Saucony Kinvara. I had been a long time Mizuno Wave Rider wearer, but after my last 70.3, the first thing I did was take off my shoes. My heels were once again blistered, my feet ached, my shoes were soaking wet and seemed 5 pounds heavier. It was time to find a new pair of running shoes.
I headed to the TriSports shoe wall and consulted with one of our expert shoe fitters. I wanted a light weight shoe with good drainage, enough cushion to run an Ironman marathon, and a lower heel-to-toe drop (around 4-6mm). I tried on the Brooks T7, the K-Swiss Blade Light, and the Saucony Kinvara. Right away the Saucony’s were noticeably different. The shoe’s upper was soft and flexible, free of unnecessary decorations, and allowed for good ventilation. The heel cup was also very pliable and securely wrapped around my narrow heel. With 4 mm of drop between the heel and toe it was the perfect shoe for transitioning to a more minimalist style of shoe.
Fast forward 5 months and I still love my Kinvaras. I am well over the “300 mile limit” and the shoes still feel like they did when they came out of the box. If you are in the market for a light weight trainer/racer with a low profile, try out the Saucony Kinvaras, and if you need a stability shoe, try the Fastwitch. Happy running!

What is joy? Merriam-Webster defines joy as “the expression or exhibition of such emotion” and “a state of happiness” – perfect emotional descriptions of the new Quintana Roo Illicito Triathlon Frameset. Triathletes will be riding for joy once they experience the QR Illicito.
Quintana Roo has always been a leader in the design of tri bikes and the Illicito takes their proven shift technology – when riding a surge of air is created from behind the front wheel and the unprecedented aerodynamics of the CDO.01 frame style enables suction to draw the wind off to the ‘clean’ side (non-drive side) of the bike – and ups the ante by removing the left seat stay and creating an even more ‘clean’ side. QR constructed a Leading Edge Absent (LEA) surface on the non drive chain-stay which results in a ‘sail’ effect. This ‘sail’ effect creates less resistance and makes for a sleeker and faster frame.
The Illicito offers more high modulus carbon fiber than any previous QR frame. A newly redesign rear brake improves braking performance plus offers increased clearance for the latest generation of wider race wheels.
The QR Illicito comes with a fork, headset, seat post and brakes.
Illicito: TriSports.com’s definition of joy!

The modern bicycle chain is a marvel of technology. Each link is comprised of two outer plates, two inner plates, two rollers and two pins. Each plate is chamfered and beveled to optimize shifting. The forces exerted on a chain during hard efforts are enormous and yet they last for thousands of miles IF properly maintained. Here are some basics principles of chain wear and maintenance.
A chain is designed to roll precisely between the teeth of the chainrings and sprockets. In order for this to happen, the distance between each link must be exact. When a chain comes out of the box, the distance between each pin is ½”. As the chain wears or “stretches”, the distance between the links increases and shifting deteriorates.
In this first picture we see a partially extracted pin in pristine condition. The mirror polish is what makes a new chain feel so smooth. (You can also see the specially shaped edges that improve shifting.)
This is the chain pin of a worn chain. Many things cause chain wear. As the chain pivots at every link, the metal erodes a tiny bit. Metal upon metal friction causes faster wear. A good chain lube will get in between the different chain parts and act as a friction barrier. Less friction = less chain wear. This chain was poorly maintained and there was no lube on the inside of the links.
Dust and dirt will also increase friction in a chain and rapidly accelerate chain wear. The problem many people have is that too much chain lube will attract dust and dirt. So the benefits of the chain lube are offset by the increased crud on their chain.
Some points about chain maintenance:
1) Some people will use a degreaser to remove the factory lubrication from a new chain and replace it with what they think is a “better” lube. What they don’t realize is that these chain parts are actually coated in a special grease before being assembled into a chain. Here is a picture of the guts of a new chain. You can see that there is grease even in the innermost parts of the chain. This original lubricant is the best for breaking in a new chain. If you want to take the excess grease off the outside of the chain, just take a rag soaked in degreaser and run the chain through it. But there is no need to degrease a brand new chain.
2) We often see bikes come in with black chain lube specks all over the rear of the bike. The chain is wet to the touch and jet black. If you run your fingers through the sludge on the chain it will be slippery but it will also feel gritty. Too much lube! The oil slick on the chain attracts dirt and the dirt gets sucked into the chain parts and your chain wears out much sooner than it should. Its like pouring sand into your car engine.
3) We are often asked, “How many miles should I go before I lube my chain?” Well, that’s an impossible question to answer. Different riding styles, riding conditions, types of lube, and cleaning are all factors in how long a chain lube will last before needing to be refreshed. The best solution is to listen to your chain as you’re pedaling. A new chain or newly lubed chain should be fairly silent. As soon as chain noise becomes apparent its time for some lube.
4) The other most often asked question regarding chains is “What is the best chain lube?” The short answer is that which lube you use isn’t as important as how you use it. At the moment, our service shop is using Dumande Original, Dumande Bio, and I’ve just begun testing Dumande Lite. My previous favorite was TriFlow, another good all around lube. There are many more out there and each particular lube has pluses and minuses based on the type of use, climate, and degree of maintenance you are willing to put up with. We may consider a review of different chain lubes in the future but for this article we’ll focus on maintenance.
How to lube a chain:
So you’ve had a new chain installed by the professionals at TriSports.com and you’ve put some miles on it. Things don’t seem as smooth and quiet as when it was new. Its time for some lube.
1) The first step is to clean your chain of the old lube(Remember, this is not a “new” chain but one that has been broken in already). Lubes work best when they are not mixed with different formulas. Pick one and stick with it for the life of the chain. You can either remove your chain and clean it in degreaser (Citrus based or something like Clean Streak) or use an on-the-bike cleaning tool like the Finish Line or Park Tool offerings. Be sure the chain has had a chance to dry off before going to step 2. Wipe the chain through a dry rag until the residual degreaser is gone.
2) With the chain on the bike, apply ONE drop of lube on each roller of the chain. I like to do this on the lower section of the chain as it sits on the bike. This way, the lube is already where it needs to go and won’t get flung off the outside of the chain as it spins around the first time.
3) Turn the cranks for a minute or so (or ride the bike). Is the chain quiet now? Can you hear yourself think again? Now run your finger along the top edge of the chain. You should see a slight wetting from the fresh lube working its way through the chain parts. If its still totally dry, repeat step 2.
4) Take a rag and wipe off the excess lube from the length of the chain. This is VERY important! Repeat this until a clean rag comes away mostly clean.
5) Go ride!
So how about you? How do you clean or lube your chain? Any chain lubes that you think we should try? What problems do you have with chain maintenance?

Its always a challenge to be on the cutting edge. Like the mad scientist, your results can make you a hero or an expensive failure. When Trisports.com was asked to build one of the first Scott Plasma Premiums with custom internal Di2, we cautiously jumped at the chance. Judging by Facebook comments and comments from coworkers who witnessed the bike in person, the TriSports.com service team came out with hero status with one of the country’s first Scott Plasma Premiums with custom routed Shimano Di2.
What made this project a challenge is the fact that the stock Plasma Premium frame is not set up for internally wired Di2. For this build we didn’t want exposed wires running along the outside of the frame. Everything would have to be routed internally, which meant heavy modifications both to the inside and outside of the frame.
There is a saying in the medical field, “Do No Harm”. That applies just as much when modifying a $4000 carbon fiber frame. Literally hours were spent drilling, grinding, sanding, and soldering in order to make this frame a reality. Great care went in to keeping the structural integrity intact and untouched.
The result is one of the most satisfying bike builds to come out of TriSports.com. Since there is no manual for this type of build, everything was planned and executed by us. We are not afraid to brag that it came out beautifully. The Di2 is integrated seamlessly inside and outside of the frame. The bike is as clean as anything you’d see in the pro field and is a perfect example of what Di2 is capable of. We look forward to doing more cutting edge builds for you in the near future.
