AiRO is a program that performs CFD (Computational Fluid Dynamics) to measure the aerodynamic impact of changes you make to a rider’s position. Definitions of CFD can be quite lengthy and detailed. Basically, it is a model that analyzes and predicts fluid flow around an object. This is very similar to what a wind tunnel…
In our latest installment of Fit Files, we get a chance to see one of our own fitting clients in the wind tunnel and review his results. Sam is a longtime client and a 50-year old triathlete standing 6’4″ and 198 lbs. I recently worked with him on the fitting and sale of his new…
Your Bicycle Seat Position is Wrong (Maybe) The correct position of your bicycle seat is essential for maximizing your riding efficiency, comfort, and safety. An appropriately adjusted saddle allows you to maintain a neutral posture with proper pelvic support while accessing as many pedaling muscle groups as possible efficiently. Whether you are a casual rider…
As I write this, the leaves are changing color, the days are a pleasant 70 degrees, and the nights are in the 50s. Almost perfect cycling weather. This being said, just because the weather is great doesn’t mean that you are enjoying your rides. Many cyclists endure varying levels of pain because they believe that…
Only I could need a second article to talk about riding a bike in circles for an hour. If you missed part one summarizing my hour record attempt, it can be found here. In part two, I’ll review my bike and equipment, training, and answer some common questions I received. Dean’s Hour Record Attempt –…
If you have a power meter mounted on your bike, you already own a mobile and accurate wind tunnel. I enjoy watching the latest YouTube videos from pro triathletes and cyclists like Lionel Sanders and Alex Dowsett publishing their wind tunnel tests in the endless quest for “free speed”. Fortunately, for those of us that…
I’ve known today’s fitting client well as he’s been my main training and tech talk partner for nearly 20 years. He also happens to be the guy that took 14 years away from triathlon, then showed up and won the Patriot Half Ironman this past summer. Needless to say that turned some heads, but for…
“Shall We Play A Game?” In the 1983 movie “War Games”, the WOPR computer, AKA “Joshua”, asks, “Shall we play a game?”. The game? Thermonuclear war. In the end, after playing tic-tac-toe against itself, the computer, thankfully, decides it can’t win the game. While it sometimes feels like tic-tac-toe is determining our fate, Artificial Intelligence…
This time trial position is my fastest yet. I’m comfortable enough to ride long time trials; I maintain more of my road bike power than ever before; and my CdA is down to 0.208. Win, win, win. Yet if I looked at this position for the first time, I’d think there’s no way it’s…
I promised a report of my most recent trip to the A2 wind tunnel back in 2021. While it took me a while to get to the write-up, I fortunately still have all the data and notes. Even better, now that time has passed, I can draw better conclusions about this trip than I could…
Background and Old Position: Up until 2017, I spent many years testing and fine tuning my aero position. I was pursuing record; records where set-up details matter a lot. I documented a lot of this in prior posts. However, I stopped riding the position I had put so much time into refining a few years…
I hadn’t been on a velodrome in 4 years. I hadn’t raced in nearly as long as taking some time off turned out longer and while it’s a story for another day it’s been a long 2 years working to return to form. Here I was at masters track nationals in Trexlertown Pennsylvania again about…
