A version of this article was originally published in Triathlete Magazine I’m interested in getting an aero helmet. How should a properly adjusted helmet fit and which helmet is the fastest? Macy, Internet Dear Macy, Multiple wind tunnel studies indicate that aero helmets offer one of the highest ratios of aero benefit to dollar cost…
Bicycle Aerodynamics Energy and Power use breakdown* % of total power consumption: Aerodynamics Total (combination of rider aerodynamics and bike aerodynamics) – 65-85% Total Bicycle Aerodynamics ≈15% of total power use and ≈25% of total aerodynamics Wheels – 5-9% of total aerodynamics Fork – 6-9% of total aerodynamics Frame – 4%-9% of total aerodynamics Other…
A version of this article was originally published in Triathlete Magazine I’m intrigued by some of the newer clip-on options to replace my Syntace C2 aerobars. My short list is the Easton EC70 Carbon, the HED Flip Lite, the Zipp clip and the Vision Tech Carbon. What is your impression of these aerobars and what…
A version of this article was originally published in Triathlete Magazine I am looking around at new triathlon bikes. I’ve read all the specs and reviews and have narrowed my search down to the Cérvelo P2K, Felt S25 and Quintana Roo Tequillo. I have test ridden the Felt and Quintana Roo and they both felt…
A version of this article was originally published in Triathlete Magazine Since Jan Ullrich started using straight aerobar extensions a couple years ago, I’ve been seeing straight extension extensions appearing under more and more pro riders. These look intriguing. Anything I should know about them before trying a pair? Seth , CT Dear Seth, The…
A version of this article was originally published in Triathlete Magazine I bought my first triathlon bike last year and initially my lower back was giving me problems. I raised my handlebars some and my back discomfort has been a lot less. However, when I compare my riding position to what the pros are riding…
Cervelo has been the industry leader in the engineering and aerodynamic design of bikes since they first showed up in triathlon in the mid-nineties. Cervelo designed the flagship P5 to be the fastest bike possible. After five years without change, they found enough details to improve upon that they released the newest 2025 version. While…
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…
We’re pretty excited about Parlee’s latest engineering creation – the Parlee RZ7 aero road bike. Why? For some of the reasons we are excited about bikes like the 2019 Cervelo S3. Aero road bikes are improving markedly in terms of rider comfort, fit and versatility. They are also becoming a bit easier to work on…
Cervelo used the by-line “Simply Faster” for years. However, as time has passed, the top aero bikes have become so fast that the ante has been upped. Today, you need to be more than simply faster to compete at the top level. While gaining some mechanical complexity over its predecessor, the 2019 Cervelo S5 encapsulates…
Zipp and Enve are two of the most respected and well-known brands in the carbon wheel world for good reason. We’ve represented both for a long-time – Zipp since our inception in ’01 and Enve since not long after their inception, back when they were called Edge Composites. The hardest thing about trying to compare…
