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?

  • meganPSLice1

    Meg Pennington – Custom bike builds and fitting

    “I wanted to thank you for such an amazing build and fit you did with my Cannondale!! I truly had an absolute blast riding it at the Lake Placid Ironman – and I’m excited to tackle the distance again to apply what I learned. I would not have had such a successful first Ironman without your incredible talent getting such a good fit!!”

  • marceves

    Marc Eves – in-person Fit on Vertex Fit Cycle

    My fitting from last fall won the bike leg in my age group at Ironman Lake Placid, and placed 3rd in my age group to qualify for Kona! Thanks for the fit!

    Pat McCrann, Endurance Nation – Multiple in-person fits, custom bike build

    Can’t say enough good things about what you have done for my bike fit and overall performance. Hard to believe you can keep finding more speed for me…thanks!!! (2015 IMTX 5th overall amateur, 4:44 bike split) – Pat McCrann, Endurance Nation – Multiple in-person fits, custom bike build

  • ECole

    EC – In-person Fit

    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 actually climbing better too! I raced the Cedar Lake Triathlon (a local super sprint that takes place every other Thursday night through the Summer) and I actually PRd the bike course and felt fantastic coming off the bike and onto the run!
    You have a gift. THANK YOU, THANK YOU! – EC – In-person Fit

  • NeilWbike

    NW – Multiple in-person fits and custom Kestrels

    “Just wanted to say thanks for selling me another great bike!

    My new Kestrel worked great in St. Croix and I got another Kona spot, despite a very choppy swim, strong winds on the bike and heat on the run. For me, it’s still all about the bike”. – NW – Multiple in-person fits and custom Kestrels

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 interesting conversation today with Paul at Princeton Carbon Works . Their Wake 6560 aero full carbon clinchers comes in under 1500 grams a set (so saves ~150 grams or more over the obvious competitors) which is nice.Especially since aero-wise they look to be better than anything out there including 80 and 90mm deep wheels that cost up to 2x as much. So notably less weight, better handling and nothing is faster. Sounds like a winning combo to me. Looking to forward to testing these in the Spring. ... See MoreSee Less

Cycling performance optimization: Lis and I had a great session on the Vertex Fit Cycle tweaking our fits while riding repeated intervals around threshold (thanks to the Vertex's Wahoo Kickr drive unit). We have both been riding essentially the same TT positions for years, but this type of iterative interval testing under heavy load on the Vertex taught us a lot. When you are working at that level and a small change suddenly makes things feel easier, you have discovered something. So I consider this the next level beyond a decent bike fit - tweaking for fit/performance optimization. You really do need a solid hour of mixed but strenuous intervals. We experimented with small changes in saddle height, seat angle, and crank length without adjusting the front end at all (and without changing the saddle's relationship to the front end of the bike - as only the Vertex can do). Instant feedback while suffering. Anything that lessens the suffering is a good thing. And in our cases we had no intentions of modifying our front end position relative to the saddle or our overall "aero profile". We can look at that later but are both pretty happy with where we are on that. ... See MoreSee Less
