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.

The first test results are in on the Catlike Rapid Tri tailess aero helmet. Sent it to a client training for IM Lake Placid whose head gets overheated easily, and "Stupid good" was how he described it. The cooling around the ears is fantastic. May be cooler than a standard road helmet. Check out catlike's video on the features:
(there is also a "good" description of what a wind tunnel is for those who don't know - "a bulky instrument - a strategically positioned fan" ).

Interesting new tail-less aero helmet from Catlike: the Rapid Tri. Looks like it will have excellent cooling. Comes with 2 magnetic visors - one with added ventilation (shown). This visor allows air to pass around the ears and out the rear of the helmet in addition to the air flowing through the overhead channels. Team Movistar has been using these in TT's on the Pro Tour. One size only, too small for my fat head unfortunately so I can't test it out! It looks as if it should fit anyone but the smallest and largest heads - listed as fitting 54-59cm. Available now in limited quantities in white, red or blue. ... See MoreSee Less

First ride on my Sarto antonio "Lampo" aero road bike. Like all Sartos this frame was hand built in Venezia, and handling, ride quality, climbing and acceleration are peerless. With a bike like this, you never need wonder if the bike is holding you back in any way. It sure seems fast too with a 21mph average for 30 miles at 250 np (Stages Cycling power meter) with minimal drafting (I was only riding with Lis who was on her Ventum - I don't get any draft from her on that thing anyway!). This bike is available for test rides if you are big enough to ride it! ... See MoreSee Less

Italian masterpiece on 2 wheels: Custom built Sarto antonio "Asola" road bike. 14.5 lbs of hand-made mitered carbon frameset with Enve aero road bars stem and seatpost, Hed Ardennes+ wheels and Shimano Dura-Ace. The soon-to-be owner of this bike will be taking delivery of her second Sarto - her first was unfortunately stolen and she had to have another one. All Sarto's are hand built to order in Venezia (even the carbon tubing is made there) so custom geometry and paint is easily accommodated. I am very excited to be building up my second personal Sarto road bike - an aero "Lampo". Pics coming soon. If you are looking for a very special one of a kind bike with craftsmanship and heritage that is hard to come by anymore, it is hard to beat a Sarto. Just ask the many Pro-Tour riders who depend on Sarto to build them their custom personal race bikes (disguised with team sponsor logos). ... See MoreSee Less
