Brand: Fit Kit Systems

The Fit Kit is a vital set of tools to measure foot length, inseam, torso, and arm length for an objective starting point for bicycle frame sizing and fitting.  These measurements comprise part of the Fit Kit System of bicycle sizing and fitting.


Every bike shop should have a Fit Kit for bike sizing and bike fitting.  The “Fit Kit” has been and continues to be the bike fitting tool kit of choice for many bike retailers.  Use it on its own or to complement other fit systems like BG Fit, Retul, Trek Precision Fit, and Guru Fit.

The Fit Kit is the standard set of tools that measure foot length, inseam, torso, and arm length for an objective starting point for bicycle frame sizing and fitting.

This approach to bike sizing develops a service-based relationship with every customer that comes through your doors.

Features & Benefits

  • Easily train staff to use it
    • Using the Fit Kit System, you can easily and quickly train your staff to select the right bike for the customer the first time:
      • Take the four basic measurements
      • Assess the rider’s physical condition and goals
      • Calculate an appropriate frame size, saddle height, and reach to the handlebars.
      • Set the saddle height.
      • Measure the reach to the handlebars.
      • Find out if you need to change out the stem.
      • Invite them to take a test ride.
      • From the floor to the door for a test ride in 10 minutes.  That’s why we call it the Quick Fit Kit.
  • An amazing bike sales tool
    • The real value of the Fit Kit is that it can be used as a sales tool; it is easy to learn; promotes confidence for the salesperson because they are not guessing what bike to put a rider on; and promotes confidence in the mind of your customer that they are buying the right size because someone is interested enough in them to take their measurements and calculate their frame size.
    • No more “eyeballing” or using only stand-over clearance to pick a size. The customers expect better, and this offers better.
    • Reduce returns because “the size is wrong”.  Buy the basics and increase your bike sales with confidence knowing you are offering your customer the proper bike frame size right from the start.
  • Bike Fitting
    • Use it to confirm that a rider is on the correct sized bike to start with, and generate recommended seat height, reach, and drop numbers for consideration in the fitting process.
    • Identify fundamental variations in anatomical proportions that are going to influence the rider’s fitted position. Perform this before you start a bike fitting and you have a baseline to work from.
    • Use in conjunction with other bike fitting tools and technologies like Retul, Guru, BG Fit, Trek Precision Fit, VelogicFit, and others.
