Aero Bike Fit Specialists
The Right Bike Fit for YOU – Guaranteed
We have been competing for more than 20 years, and as Engineers have studied and experimented with bike fit from day one. We have created our own fit protocols, philosophy, and tools, including our patented automated Vertex Fit Cycle (yes we designed, patented and built our own automated computerized fit simulator from scratch). We pioneered online fitting. We focus on aero – triathlon and time trial – bike fitting. We do road bike fits too, but aero is our heart and soul. Thousands of happy clients and countless victories later (including multiple Ironman World and National Champions), we still keep learning and honing our craft every day.

Vertex Fit Cycle
We couldn’t find a fit bike that had the features we needed, so we patented and built our own. All in-person fits include time on the Vertex, so the athlete can immediately feel the impact of fit changes. FOr more information, visit vertexfitsystems.com or download the White Paper.

Bike Availability Update
Quick update on the state of the cycling industry and availability of bikes and components. Short story: it’s ugly and getting worse. The disruptions to supply chains and manufacturing have been massive and continue to ripple like waves through the industry. Factories in Asia continue to be shut down at random times indefinitely. Shipping (on real ships) is an utter mess. This is what happens folks when govts randomly shut things down. No amount of stimulus will help this – the second and third-order effects are just getting revved up. This is coming to many other industries as well if […]
How Fast Was Kona 2018 vs Historical Averages?
The fast year is ALWAYS the year you don’t go. It sure seems that way, right? Well this year the data is indisputable. 2018 is by far the fastest year for the Kona Ironman World Championships in the last 11, and maybe the fastest ever. I haven’t heard how many age-group records fell, but obviously the pro records were smashed and at least the overall female AG record was annihilated by a 45 year old no less (and with it Lisbeth’s 8-year old 45-49 course record). First, let’s talk about “normal” Kona and what can cause it to be fast […]
Craig Alexander’s Ironman Tips Courtesy of the Argon 18 Kona Team Barbecue
One thing you notice in Kona is that some companies go out of their way to support their customers. Lately the bigger names in the bike world are notable by their absence, Cervelo being the exception. Several smaller brands also work hard to make sure their customers are taken care of led by Ventum. Ceepo is another. Argon 18 continues to be a standout, as they have here for years, with their own team of mechanics toiling all week in the Kona heat. You have never seen more Argon 18s, Ceepos or Ventums than you will see here, so maybe […]
Lone Star Adventures: Lisbeth’s Ironman Texas 2016 Race Report
Do I recommend starting an ironman build 7 weeks before a race? My plan was ironman Germany later in the summer but due to circumstances too boring to detail, I jumped on the opportunity to race Texas, giving me, you guessed it, 7 weeks to build and taper. Two goals: race exactly fast enough to secure a spot (i.e., top 2 AG) and minimize damage for quick recovery. I believed, if ironman fit, I could race conservatively and meet my goals. I thought I would give Coach Al a conniption but he jumped at the challenge in Al style and […]
Kona AG Women Bike Split Analysis: How fast do you need to be, and how did Lis do in 2015?
I have been spending some time analyzing Kona bike split data for the last 8 years. Coincidentally, this is when Lisbeth started racing Kona consistently (she also did it in 1996 pre-kids). I wanted to see what years were “tough” years, and how Lis has fared versus the fastest women bikers, fastest overall finishers, and masters women in general. I found the results pretty interesting both on a general basis and relative to Lisbeth’s performance over the years. One reason I undertook this task was that Lis felt she had a bad race this year, finishing second in her AG. […]
