Fit for an Existing Bike

First measure, then improve

If you have an existing bike, we are working with a fixed frame size.  Most of our clients have an appropriately sized frame for their body dimensions and need some adjustments (stem, saddle, seatpost, handlebar, etc.) to get the bike "dialed-in" according to their particular needs. If you buy your bike through ARB, we will help you choose the right size frame! On occasion, we do get some clients that come in with an inappropriately-sized frame for their body dimensions. At this point, we will do everything we can to make the bike fit as optimally as possible, given the limiting factor of frame size.

We offer four types of bike fits for someone who has an existing bike, including those who buy their bike through ARB. Our fits can be done on all types of bikes including road, triathlon/time trial, mountain, cyclocross, commuter/hybrid, track and touring.

  1. Cleat/Shoe/Pedal Interface Fit - All Bikes
  2. Basic (Static) Fit - Road & All Other Bikes
  3. Advanced 3D Retul (Dynamic) Fit - Road & All Other Bikes
  4. Advanced 3D Retul (Dynamic) on DFU Fit - Triathlon/TT Specific Bikes  

Cleat/Shoe/Pedal Interface Fit - For all Bikes
This fit specifically addresses the cleat/shoe/pedal "system."  It ensures that your clipless pedal interface is positioned according to your natural leg rotation during the pedal stroke - eliminating stress on the knee, ankle and hip.  This fit would be the starting point for anyone who has discomfort/pain in the leg or foot.  And this fit should be done whenever you have purchased your first clipless pedals or changed shoes, cleats or pedals.  For example, you have switched from a pair of Giro shoes to Sidi's or Look pedals to Speedplay Zero's. 

Our Cleat/Shoe/Pedal Interface Fit session includes:    

  1. Check for neutral cleat position as starting point
  2. Installation of the Fit KitTM RADS pedals on your bike
  3. Determine correct "Q Factor" 
  4. Analysis of rider's lower leg rotation while pedaling
  5. Adjustment of cleats on shoe to accomodate each leg's natural rotation.

Basic (Static) Fit - For Road & all other bikes EXCEPT Triathlon/TT specific
This fit is appropriate for someone seeking his or her first comprehensive fit and/or doesn't quite need the precision provided by the Advanced Retul Fit. This fit is conducted on your own bike set up on a trainer. Our trained fit specialist will evaluate your position utilizing standard tools of the trade including a measuring tape, plumb-bob, goniometer, laser and adjustable stem. The cost of this fit is waived for anyone who purchases a new bike from ARB Cyclery.

Our Basic Fit session includes: 

  1. Personal interview to determine riding style, goals, physical concerns and limitations. 
  2. Comprehensive body analysis using Fit Kit™ measurement tools.
  3. Check for neutral cleat position.
  4. Evaluation of position on your current bike.
  5. Adjust bike to make the necessary improvements, as recommended by fit specialist. 
  6. Receive written reports of key measurements. 
  7. Follow up session within the first month to fine tune the fit, as necessary.
Cost:  $75
Cost:  $125

Advanced 3D Retül (Dynamic) Fit For Road & all other bikes EXCEPT Triathlon/TT Specific
The Retul fit offers greater measurement precision and more closely mimics the way you ride on the road. The Advanced Retül fit is appropriate for anyone who wants the most advanced system on the market for measuring a rider's position on the bike. Do not confuse Retul with video-based systems. Retul is far superior and measures the rider with true 3D accuracy WHILE he/she pedals the bike under load. Whether you're a racer looking to finish on the podium, or a century rider looking to finish strong and in comfort, a Retül fit can give you that edge. 

Our Advanced Retül Fit session includes: 

  1. Personal interview to determine riding style, goals, physical concerns and limitations. 
  2. Physical assessment to determine flexibility of hamstrings, quads and IT bands as well as joint mobility; Evaluation of foot/hip/knee kinetics, structural differences and functional strength.
  3. Check for neutral cleat position.
  4. Comprehensive body analysis using Fit Kit™ measurement tools.
  5. Dynamic testing on your bike using Retül's 3D Motion Capture technology to determine proper positioning. Perform on each side to determine any asymmetries. 
  6. Adjust bike to make the necessary improvements and retest with Retül to compare. Repeat the process as many times as needed to achieve the optimum position.
  7. Capture the geometry of the bike using the Zinn feature of Retül. Key measurements provided in report. 
  8. Receive a Retül-generated report of all the key measurements of your position on the bike, both before and after. 
  9. Follow up session within the first month to fine tune the fit, as necessary.

Cost: $250

with Cleat/Shoe/Pedal Interface Fit:  $300


Advanced 3D Retül Fit on Dynamic Fit Unit For Triathon/TT Specific Bikes Only
Our Retul motion capture fit system combined with the infinite adjustability of the Dynamic Fit Unit (DFU) ensures the best measurement/adjustability protocol to completely dial in your triathlon or time trial position.  The primary advantage of the DFU is that it allows us to make real-time, on the fly adjustments as you pedal. There is no stopping and getting off the bike to make manual saddle and stem changes. You get real-time feedback to even the slightest changes in handlebar and saddle position.  We can even save different fit positions and can toggle back and forth between them. 

Our Advanced Retul on DFU session includes the same steps as in the Retul Fit outlined above.  The main difference is that the dynamic testing is done on the DFU instead of your own bike.  Once your ideal XY coordinates are determined, we will then set up your existing bike to match.  

Cost: $300
with Cleat/Shoe/Pedal Interface Fit: $350

What Exactly is Retül?
The Retül system is a state-of-the-art, motion capture system designed specifically for collecting the most accurate and realistic cycling specific data in three dimensions. By gathering data from eight key anatomical points in your riding position, we are able to profile existing (before) and ideal (after) angles to meet your specific needs.

The results...more efficiency, power output, performance and comfort! For a more detailed description of the Retül system, click here.
