Aero Bike Fit Specialists

The Right 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.  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 hundreds of customers. Talk to the coaches who send us their athletes. We look forward to working with you.

What Do Our Clients Say?

  • NW – Multiple in-person fits and custom Kestrels

    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

  • 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

  • AH – online fit

    AH – online fit

    “I just wanted to send you a quick note to thank you again for the position you gave me last year. I recently finished my second IM 70.3 and dropped about 40 minutes off my bike split. I think its pretty amazing that you’re able to put someone in a good position without ever stepping foot in the same room! The online pre-buy fit works out great for a beginner triathlete like myself.”- AH, online fit

  • AD – in-person fit, custom Blue Triad SL

    AD – in-person fit, custom Blue Triad SL

    “Yes, Kona bound!!! There were 3 spots and I was 3rd. :) The bike was amazing. It felt like I was flying on the highway stretches and it climbed really well. I was totally comfortable in the aero bars and with the fit. I didn’t have fatigue on the second loop of ending hills. Previously, I would feel the hills on the second loop and it wasn’t the case yesterday. Thank you again!!! The new bike and fit were a huge part of this outcome.” -AD, in person fit, custom Blue Triad SL

  • TW – online prebuy and in-person fit

    TW – online prebuy and in-person fit

    “I just wanted to thank you again for the awesome fitting. With your help I won my age group at Ironman Maryland in 10:31 and am going to Kona in 2015! A dream come true! As a 60 year old man with lousy flexibility I am SO comfortable on that bike. Out of 5 hrs. 10 min. I think I  was in the aerobars about 5:08. Same for Carol who had a 1 1/2 PR on her P3!” – TW, online prebuy and in-person fit

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.

What I did on my "vacation": rebuilt ttbikefit.com/ from the ground up. The original was initially built as early as 2006 so it was a wee-bit outdated code-wise. I think it came out well. Responsive too - i.e. it adapts to mobile browsers (timely since Google has been threatening everyone with non-responsive sites - something about sending you to search purgatory and furthermore you can't have a self-driving car in the future nah nah-nah nah nah-nah). Probably not perfect and some more stuff will be added. Check it out and let me know if you find any bugs! ... See MoreSee Less

@Falco_Bike V beam bike - our latest custom build. If you haven't seen one of these in person, it is hard to see from photos just how elegantly it is shaped. This was a size L so it was big enough for me to give it a quick test ride - very impressed with the stiffness and responsiveness. There is no doubt in my mind that the beam design is one of the fastest aero profiles possible. My old Softride Power V was fast as heck (confirmed in the MIT wind tunnel) even if it weighed a ton and wasn't very stiff. Falco seems to have solved the stiffness issue, and the weight is comparable to many other high-aspect ratio aero frame designs. Note that these are available now in a variety of sizes and graphics, and we have the fit envelope wired. It comes as frame/brakes/stem and will be built to your exact specs. (3 photos) ...

Cool video of Leanda Cave in A2 wind tunnel trying out our new fit on her Ventum One. Don't look too closely at those aerobars - we concocted them from 3 sets of bars we had on hand in order to get the cup reach/stack and hand position that we determined on the Vertex Fit Cycle. instagram.com/p/05nRuEtrZJ/ ...
