Aero Bike Fit Specialists
The Right Aero 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 fitbike. 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, we still keep learning and honing our craft every day.
We stand behind and have pride in our work. It actually matters to us that our services help YOU have the best athletic experience possible. Looking for the right tri bike? We will find it for you. If you have a bike already we will make sure your fit is optimized. Either way, you will LOVE your bike. That is our money-back pledge. If something isn’t right, we will fix it or give you a full refund on any and all fitting charges. No bull. Please talk to any of our thousands of customers. Talk to the coaches who send us their athletes. We look forward to working with you.

What Do Our Clients Say?
The Vertex Fit Cycle by TTBikeFit – Available January 2017
We developed and patented the Vertex Fit Cycle because we could not find a satisfactory fit platform on the market. Frankly, we cannot imagine fitting without this amazing machine. The Vertex is the ONLY fitbike that keeps the rider stationary and move the contact points around the rider. This allows us to easily change one fit variable while keeping other variable constant. Traditional fitbike designs cannot do this since the saddle and rider move. After working with our production prototype (shown in the lower 2 videos) for 2 years in our studio, we are finally ready to release the production version (top video). We plan to sell initially very limited numbers of the Vertex to select fitters, coaches, and teams. Please contact us if interested.

Kona Ironman World Champs 2016 – Pro Super Slo-Mo
The first several male pros passing mile 110 on the Queen K in 2016 – shot at 240 fps.
Ironman Run Form – Gliders vs. Gazelles
We lay out the case for an alternative running style for Ironman events. While classic run technique is required at paces faster than about 6min/mile, athletes targeting slower paces may benefit from focusing on the dramatically different gliding run style.
Norseman Xtreme 2012 – Our Journey
Lisbeth competes in the 2012 Norseman Xtreme – World’s toughest Iron distance race – in her home country of Norway. Lis beat the existing women’s course record, finishing third. Definitely a bucket-list race.
Pro Bike Position Analysis: Kienle vs Potts vs TO
We compare the bike positions of three of the top finishers in Kona 2012: Sebastian Kienle, Andy Potts, and Tim O’Donnell, using motion analysis. Footage shot at 300 fps at mile 110 on the Queen K.
Interesting, detailed discussion today with Princeton Carbon Works regarding their new aero wheel. Wind tunnel results indicate it could save ~10 watts vs a 404. Look forward to testing these out soon! www.princetoncarbon.com/
If you travel 6000 Km (3700 miles) for a new bike, it better be good! Our friend and ironguides athlete Stefano picked up his custom Ventum One today - custom built and fit on the Vertex Fit Cycle- on his way from Lima, Peru to Syracuse 70.3 .
Amazing feedback on Argon 18 Nitrogen aero road bike - I have 2 of them out in the wild and it seems like a fantastic bike from these reviews. I guess the fitting was ok too...
"To begin, the bike is very fast, on a flat road, in an aero tuck, the bike just hauls. It really feels like every pedal stroke goes right to the wheels and it feels super slippery in the wind. For an “aero road” bike it climbs remarkably well, Finally, it handles like it’s on rails, it is stable and corners very well. If I compare it to my other “aero road” bike - my Cervelo S3 - I would have to say it is much more nimble and climbs much better. The S3 is also a fast bike but to me it always felt a little “clunky” and “heavy” - it didn’t climb well at all, hammering up a hill the beck end of the bike felt kind of mushy (compared to a Cervelo R5 (a climbing bike) where the back end felt like it wanted to propel you forward on a climb) and I never felt like it handled and cornered all that well. it always felt kind of “cumbersome” to me. None of that with the Nitrogen.
By the way, you reallly nailed the fit - bike fit like a glove from the first moment I sat on it. " - FR
"It's such a great bike - handles beautifully and is so responsive and quick, but I feel very solid on it. It's a comfortable ride and I've had no problems with the brakes. I've taken it out four times so far on rides from 18 -34 miles on a variety of long uphills, flats and curvy downhills, and I love it more every time I ride it. The thing I think that is making the biggest difference for me though is the fit of the bike - it's amazing. I feel so much better being lower on the bike, I'm more comfortable, feel like I have better control on the bike and more power. It's at least a 1000% improvement. It fits me so perfectly. I can't thank you enough for your expertise, and taking the time to find the perfect riding position and bike for me. I will definitely be back when I am ready to buy a tri bike." - KD

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 […]
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 […]
