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.

    I wanted to send you an email just to let you know how GREAT my “new” bike (fit) is! I rode over 100 miles on it last weekend, after the fit, and felt so strong and comfortable. I’m so shocked how effortless the power and speed are now (especially when I’m in aero). And, I’m […]

The Vertex Fit Cycle by TTBikeFit – Available NOW (October 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. We plan to sell initially very limited numbers of the Vertex to select fitters, coaches, and teams. Please see vertexfitsystems.com for more info or contact us if interested.

Another great fit session with Mid-Atlantic Multisport athlete and Kona qualifier Mark Dooley aboard 1 of 2 Vertex Fit Cycles in operation in the US (the other being at TTBikeFit headquarters in RI). After testing a wide range of positions and varying length cranks, we were able to provide Mark with a more comfortable, powerful, and aero position (via more skeletal support of his upper body and use of shorter 160mm cranks to open his hip angle)...job done! #bikefit #bikefitting #bikefitter #vertexfitcycle

Even if you have been riding a sub-optimal bike position for quite some time, it doesn't take long for a new better position, even if more "aggressive", to win you over. This video starts with the athlete in his new TTBikeFit position as determined on the Vertex Fit Cycle. I then toggle his old setup on the Vertex and before he even gets all the way back to it the torture begins... Of course we then duplicated the new position on his Specialized Bicycles Shiv. ...
