TriSports Introduces Patented Hybrid Shave Technology

April 1, 2012 on 10:13 am | In Announcements, Random Musings, Tech Tips | No Comments

Tucson, AZ  (April, 1, 2012):, 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 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.”

TriSports Hybrid Shave Technology ResultsThe final results comparing 1) Hairy leading edge, 2) Fully shaved leg, 3)’s Patented Hybrid Shave Technology

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 partial differential equations for the continuity and Navier–Stokes for a two-dimensional steady incompressible flow with Cartesian coordinates.

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.

For the love of Saucony

February 10, 2012 on 11:18 am | In Employee Adventures, Product Information, Random Musings, Tech Tips | 2 Comments

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.

The TriSports Shoe Wall

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.

Saucony Kinvara

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!

The Joy of the Quintana Roo Illicito Triathlon Frameset

November 18, 2011 on 6:00 am | In Product Information, Tech Tips | No Comments

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 2012 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. president Seton Claggett clocks the fastest bike split at the 2011 Tinfoilman Triathlon in Tucson, AZ.

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:’s definition of joy!
