Bike Fit
Why need a Bike Fit?
A proper bike fit puts a rider in an optimal position for comfort and injury free riding. Proper bike fit also helps you to get the most power and aerodynamics out of your position based on what type of riding or competing you customarily engage it. With the combined experience of hundreds of bike fits on beginner to professional athletes we will work with your specific body type to ensure you get the most efficient position on your bike.
SE and Retül
Source Endurance is the only business in the region which uses the Retül Fit System in order to put a rider in the optimum position on their bike. Source Endurance fit technicians use a proprietary method of measuring limb length, gate, trunk length, and feet to place a rider in a comfortable yet powerful position. With the help of Retül Fit System 3D imagery is used to analyze hip, shoulder, knee and ankle movement and angles to ensure that a rider is in the best possible position that minimizes unnecessary movement on the bike. Asymmetry and oscillation are addressed down to the millimeter or degree of movement with instant feedback on how a rider adapts to changes in positioning.
SE Metabolic Fit
Just recently, Source Endurance announced a fit service that measures metabolic cost to maximize a rider's efficiency on a bike. This is measured through a pre test on our Parvo Medics Metabolic Cart during a fitness assessment on our state-of-the-art SRM Ergometer. During the test a protocol is utilized to get a rider to a RER (Respiratory Exchange Ratio) of 1.0 and the power produced by a rider is verified at this distinct RER mark in his original riding position. Then, the SE fit technicians disconnect the Metabolic Cart from the rider and use a proprietary method of measuring limb length, gate, trunk length, and feet to place a rider in a comfortable, yet powerful position on the SRM ergometer. The Retül Fit System with 3D imagery is now used to ensure that a rider is in his/her best possible position that minimizes unnecessary movement on the bike. Once the positioning has been set to where a rider is most comfortable and efficient the SE fit technicians set the resistance of the ergometer back to the previous power at RER 1.0 wattage and reattach the Metabolic Cart to the rider. With those modifications a riders metabolic cost for riding at that intensity will be minimized, thus improving a rider's performance.

Get fitted like the Pro's
Thanks to the Retül Fit System, bike fits with Source Endurance are performed with the same level of expertise and knowledge like many Olympic and Elite level athletes have been fitted before. Two of the most accomplished time trialists in the world, David Zabriskie and David Millar (both Team Slipstream Sports/Chipotle H30), have been fitted recently using the exact same system like Source Endurance can offer at their office in Austin, TX.
