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!

  • patMcCrannIMTX

    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 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.

Hed Jet+ aero race wheels limited time offer: we will match/beat ANY online price on Hed Jet6+ sets. Includes mounting of tires and cassette install if needed. These are our wheels of choice, we have been using Heds since the beginning (see pic of Lis in Kona above, or my mid-90's Softride with an early 90s Hed Cx below). Great for tri or road racing. Aluminum braking surface + WIDE rim makes for a much better ride than carbon clinchers. Aero is as good as anything out there. Email or PM for pricing. ... See MoreSee Less

The best tri bike that isn't even on your radar... I have 300 miles on mine and let me tell you, this bike takes your best effort and comes back with, "is that all you got? Take this!" in the form of ludicrous speed. Never have I had a tri bike anywhere near this laterally stiff - where an XL frame feels like it is transferring every watt to the road. Yes it is vertically stiff too, so those looking for bum-coddling need not apply. If you want to go fast though it should be on your radar. It also feels very fast aero-wise as I am seeing some surprising speeds. Ever since I first saw the prototypes in Kona, I have wanted to try one as it looked like an excellent design to my eye. Oh yeah - I am talking about the LG Garneau Gennix TR1 (do they even make BIKES? Yes - road bikes too). Rumor has it that Sanders guy goes pretty darn fast on his. As a bonus you can get it custom painted by LG's Dream Factory for a few hundred bucks extra. Mine was. No copying. Look for a full review soon. ... See MoreSee Less
