ERO Dynamic Fit & Aero Test

ERO Dynamic Powered by TriRig

In partnership with TriRig, ERO Dynamic is the most advanced bike fit found anywhere. Offering the ability to definitetively identify your best aero position, this service allows you to quickly evaluate different positions to determine which is most comfortable, most aero, or both while riding one of the most advanced bikes ever made, the TriRig Omni. Beyond position, it also allows you to test aero helmets, clothing, or anything else not related to your bike. Here's how it works...

A Little Background

In 2013, ERO Sports was the first to offer aero testing on the Velodrome using the revolutionary Alphamantis Track Aero System. A less expensive alternative to wind tunnel testing, the system took the cycling world by storm, and is now used at Velodromes around the Globe. Pro Tour teams, National Federations, Pro Triathletes, and age group athletes everywhere now use the system to conduct accurate aero testing at about 1/3 the cost of wind tunnel testing. And, while the system has proven accurate, it's not without challenges.

The difficulty in aero testing on the Velodrome really comes down to time. Each test lasts approx 2 hours; however, much of that time, often the majority of that time, is spent not actually aero testing, but making changes to equipment. As most of you know, many modern TT/Tri bikes integration makes position changes difficult and very time consuming. As anyone who has tested on the Velodrome or in the wind tunnel will tell you, wasted testing time is wasted money. 

Wasted time also has other consequences. Velodrome testing is a preferred method of aero testing because the athlete is actually riding, so the interaction between rider and bike is included in the results. However, as the athlete sits around waiting for changes to their bike to be made, their body begins to go into recovery mode. Muscles stiffen, and the results are impacted...quite significantly. There's nothing wrong with the system, mind you, it's your body that is actually moving differently changing your drag from previous runs. Accuracy is effected, and the results come into question.

Poor bike maintenance and power meter inaccuracy are also issues we deal with which effect results.

So, there are many challenges to aero testing. ERO Dynamic solves these problems to make the testing more time efficient, more accurate, and less expensive!

The Service

ERO Dynamic is either 2 services in one, or a standalone service.

  1. Bike Fit and Aero Test combination - $645: A full bike fit followed by a One Hour Aero Test.
  2. Standalone One Hour Aero Test - $350


Beginning with the fit coordinates found during your fit, or using your current fit coordinates, we test several positions to determine which is optimal. Because we use the TriRig Omni with the Alpha One aero bar, these changes can be made in seconds for efficient, accurate testing.

Your test data will include results from positions near your aero-optimal position. Why? Because we want you armed with information. Perhaps your aero-optimal position isn't your most comfortable. We want you to know exactly how much time you're giving choosing the "less aero" position over aero-optimal. After all, if it's a small amount of time, perhaps less optimal is the better overall choice?

The service can also be used to test clothing and helmets quickly and accurately saving time and money.

The Equipment
  1. Bike: TriRig Omni - One of the most advanced aero bikes ever designed and quite possibly the fastest aerodynamically.
  2. Aero Bar: TriRig Alpha One - This incredibly adjustable aero bar turns the Omni into a rolling fit bike.
  3. Power Meter PowerTap G3 Hub - A consistent & reliable power meter which also acts as an excellent speed sensor.

The Omni, combined with the Alpha One aero bar, gives us the ability to replicate and quickly adjust positions for testing. For all intents and purposes, it's a rolling fit bike. You're able to evaluate the different positions for both comfort and aerodynamics with ease, and replicate the position found to be most optimal on your own bike.

Why ERO Dynamic?
  1. The best, most reliable, and accurate way to test your personal aerodynamics.
  2. Saves time & money - efficiency for faster, less expensive aero testing.
  3. Eliminates the many obstacles to achieving dependable aero data.
  4. You get to ride one of the coolest bikes in the world!
