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 Vertex Fit Cycle (yes we designed, patented and built our own automated computerized fit simulator from scratch). 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 (including multiple Ironman World and National Champions), 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, and build it to your dream specs and perfect fit. 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?
Anthony Leroux – In-Person Vertex Fit
“Hey Todd! Just wanted to follow up and say how much better I feel on the bike!
I did IM 70.3 Atlantic City in September and posted a 13 minute bike PB, when I was in admittedly not as prepared as 2017. This was in spite of a pretty nasty crash I got into due to rain and a little stupidity. I was able to stay aero longer and much more comfortable thanks to your help. It also allowed me to be fresh enough to run 10 minutes faster for the half marathon.
Much appreciated! I’ll be working on getting my head down this winter!”
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!!”

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!!! (2018 Kona 9:31, 4:45 bikesplit; 2015 IMTX 5th overall amateur, 4:44 bike split) – Pat McCrann, Head Honcho Endurance Nation – Multiple in-person fits and custom bike builds
Although this is not the bike Jan raced on in Kona, the setup is mostly the same. For the race, he switched to an Elite aero bottle on the down tube and ZIpp 808 wheels. Besides the overall angularity of Canyon's latest superbike, the front end treatment is also striking. The hydration unit hangs in front of the head tube and sits on top of the stem. A trapezoidal bento box blends seamlessly with the back of the bottle. Jan uses a Sram Quarq power meter and a Fizik Tritone nose-less saddle. 
Jan rides with his elbows jammed together. This CAN certainly be more aero, it can also be quite uncomfortable for most folks. He also runs a relatively low hand position in a time where many are re-recognizing the potential aero benefits of higher hands. The base bar is quite square and has integrated rubber grips. It also sits very low due to the integrated stem design. Note the clean positioning of the drinking straw and the spacious bento. 
Is there a curve anywhere on this bike? Actually there is - the leading edge of the bottle is curved. Obviously Canyon makes generous use of Kamm-type truncated airfoils. But you have to wonder if all those square edges are as aero as they could be - like the trailing edge of the bento and the bottom of the hydration bottle, not to mention the very stubby square-section basebars. Looks like aesthetics came into play here, but in the end maybe it makes very little difference in performance. 
Frodo uses Sram Red E-tap "wireless" shifting. Note that there are still plenty of wires in the cockpit area connecting the shifter "blips" to the control box - they are just well hidden within Canyon's spacious front end storage. The small grey box attached to the derailleur is the removable battery - each derailleur has its own and they can be swapped between derailleurs as well. 
The rear hydration mount is integrated with the seat post. See that little fin in front of the seatpost on the top tube? That is a lid for yet another storage chamber within the triangular frame gusset. 
Frodo's position looked great. Move along, nothing to complain about here. 
Andreas Raelert's one-off Cube C:68 ranks as one of the most striking bikes in Kona this year. F1 engineers Swiss Side pulled out all the stops to make this bike as aero as possible. Yet, most of the aero features are similar to those found on other superbikes - the seat tube gusset (Canyon), the smoothly-integrated front end (Scott), the deep aspect-ratio head tube (Cervelo and Scott), the kinked chain stays (Blue), and the "big block" carbon (Felt). 
Unlike on Frodo's Canyon, the front hydration unit is practically sealed to the front tire. Clearly Swiss Side's aim here was to divert flow around the fork/wheel complex. Others have gone opposite way by widening the fork leaving large gaps between the front wheel so that air can presumably flow between the wheel and fork. This is a touchy area in the aero world - two objects with a gap between them can "act" like one big object to the air flow (bad). So maybe best to keep everything narrow and force the air around everything. 
The bars are modified Profile Aerias. Note that Andreas chose Shimano Pro elbow cups though. No BTA bottle here - instead we have a Garmin affixed with electrical tape. Aerobar shifters are the Dura-Ace 1-button type (they only operate the rear derailleur in one direction or the other). You get another good look here at the front hydration unit, with TRP brakes just barely peaking out. Tires? The ubiquitous Conti GP 4000 S2. 
He actually left it unaccompanied for a short while in the chute. Andreas was running Rotor 3D cranks, FSA aero rings, and a Power2Max power meter. Wheels are Swiss Side Hadrons. Presumably they are not intended to super-collide - just go fast. And yes, those are only (GASP) Ultegra 6870 Di2 derailleurs - probably cost him .001 watts versus Dura Ace. As noted before, Andreas did not run a BTA bottle, but chose a frame-mounted aero bottle and two cages fastened under the rear of the saddle. Gotta wonder if Swiss SIde approved of the frame bottle and lack of BTA, as both of these generally increase drag. 
Andreas' fit was excellent on the Cube. Like with Frodo's fit, it is hard to complain about anything here. Notice the Zipp rear wheel, courtesy of neutral support after a flat. Even so, Raelert's bike time was only minutes off the top split. 
Dave Davala – In-Person Vertex Fit – National Champion
“Hi Todd:
It was a pleasure meeting you today. I was very impressed with your knowledge and professionalism. The bike fit experience was the best I have ever had. For the first time, I feel confident that the bike is fit specifically to me and not just randomly. I will highly recommend you to all my multi sport friends. Again, thanks for the personal attention. I will definitely be back when it’s time for a new bike. I’ll keep you posted on fit results.”
(Results:) “Just wanted to let you know how I did a Aquabike long course Nationals. I won my age group and am now a National Champion. I averaged 24.4 mph for the 56m course with 254 avg.power and 259 normalized power. The amazing thing was that I stayed in the aero position the entire race. I felt great and pushed pretty much the same wattage over the entire race. Probably could of gone harder, but was afraid I might of run out of gas. I had the 6th fastest bike time out of all aquabikers. I am certain that the bike fit contributed to this result. Thank you for this.”
