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.

    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

  • EC – In-person Fit

    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

    “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

  • MB, in-person fit and custom Fuji Norcom Straight

    MB, in-person fit and custom Fuji Norcom Straight

    “Just wanted to give you a heads up on the race yesterday:
    The bike was amazing!!! I’ve never felt so strong in a race, and overtook soooo many athletes!
    Finished the bike in 2.49, 7th time in my 30-34 AG, which I am very very happy with, for my first race this season and first 70.3. Above all, my legs felt great after the bike and I could continue with a decent run and negative split! Happy. Thanks for the great fitting! “- MB, in-person fit and custom Fuji Norcom Straight

The Vertex Fit Cycle by TTBikeFit

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. We plan to sell initially very limited numbers of the Vertex to interested fitters, coaches, and teams. Please contact us if interested.

Great tri bike fit session with Endurance Nation team member Jamie F. Flew in from SC with his P2 to get dialed in on the Vertex Fit Cycle with the intention of getting a bit more aggressive and working out some saddle issues. After many trials an ISM SEAT PN1.1 did the trick. We also got him a good bit lower in front, while determining his current fit limits on stack and reach. The Vertex is unbeatable for this. Jamie is a good example of someone who is not going to fit on most bikes, at least in stock configuration- very long torso and relatively short legs. Even on his 61cm P2 we were at the stack limit with low-stack bars, flat stem and low profile headset cap, yet he really needs all the reach he can get from a long frame like this. ...

Need a new bike Computer? Wahoo Fitness' new Elemnt is worth a serious look. I have been riding with it for the past few weeks and I am no longer looking at my Garmin on the bike. See the vid below for features, but I really like: big high contrast screen where I can see all the data clearly even on the view that shows ten parameters. No squinting needed. Easy to see in bright sun. Easy, intuitive setup using iPhone (or Android) app. No need to constantly flip through pages to see all the data. Shows texts and phone calls and I can actually READ the notifications easily. Many other cool features I have not tried yet but I am hooked. Downside? It is on the large side. Not an issue unless you have a really busy/compact cockpit on your tri bike. No issue at all for roadies. Comes with several mounts as well. ... See MoreSee Less

A couple of recent tri fits with 2 Kona athletes: Coach Amy D' on her new Team Timex ride, and Brendan C on his new custom fit/built Argon 18 E-117. With Amy we pretty much duplicated our prior fit (this is bike #4?!) on the new Trek. For Brendan, who usually relies on his run, we made some major changes to his prior Kona fit (seen in the third pic below) to get him more aero and comfortable. He reports seeing his highest power test numbers ever! (Did I mention he is way more aero too?). ... See MoreSee Less

Look for us tomorrow at the Tri-Mania Summit and Expo in Boston if you'd like to check out some new superbikes: Ventum One, or Argon 18 E-117 and E-119+, or if you'd just like to talk bike fit. Heck, we can even tell you exactly what bikes will fit you if you have your current bike along and like the fit- we'll measure it up and run it through our calculators. We are not bringing the Vertex Fit Cycle this year - the new production model is soon to be released and all efforts are focused on getting it ready! ... See MoreSee Less
