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.

CONCIERGE-LEVEL SERVICE: 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?

Dave Davala – In-Person Vertex Fit – National Champion

“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 felt confident that the bike was fit specifically to me and not just randomly. As a result I won my age group and am now a National Champion. The amazing thing was that I stayed in the aero position the entire race. I am certain that the bike fit contributed to this result. I will highly recommend you to all my multi sport friends.”

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!!”

(Kona qualifier 2018, sub 11 Kona 2018)

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

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

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!

See you in hawaii! – in-person Fit on Vertex Fit Cycle

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

“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

“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

“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

“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

AC, online and in-person fits

“Big thank you for my bike fit, laid down a 5:22 in Chattanooga and went on to PR the run and PR the race with a 10:20 (a 59′ PR)!” – AC, online and in-person fits
