"Just rode the Chelan half iron course...
the bike was perfect! It has never been
so smooth! You will be the only person
to work on it from now on!! Thanks a
million - Jim Kozak!"


Bike Builds
CycleMetrix does complete bike builds from the frame up if you choose to pick your own selection of components and wheels. We can also set up your boxed factory bike, be it a new purchase or one you’ve shipped in for Ironman Coeur d’Alene.


Tune-ups, Service, and Repairs
Like your car, your pet, or yourself, your bike will live a longer, healthier, and happier life if you take care of it and do periodic maintenance. But like everything else (including yourself) sometimes something breaks or get’s maladjusted and then you have a performance problem. If that’s the case, CycleMetrix has you covered with everything from minor cable adjustments or flat repair to complete bike overhauls. We also stock bicycle maintenance supplies, lubes, tires, tubes, and tools.



Full Service Bike Fitting
Over the last ten years bike fitting has rapidly developed into a technical science blending knowledge of aerodynamics, biomechanics, and exercise physiology with in-depth knowledge of current bicycle and accessory design. Professional bicycle fitting is a dynamic process that seeks to blend aerodynamics, power output, and comfort.

Optimal bicycle position is influenced by the event s the rider takes part in, be it a cross country tour, a ten mile time trial, an Ironman triathlon, or a 20 mile mountain bike race. It is also greatly influenced by the rider’s physical build, flexibility, previous injuries, and their level of bike handling skill. The rider’s position on the bike should be sustainable for the duration of the event he or she chooses to participate in. Aerodynamics, comfort, and power output are co-dependent factors. Overemphasis of any one factor will negatively influence one or both of the others. The superior bike fit is a blend of them all.

There are close to a dozen popular schools of bike fitting. Each has its own philosophy and particular set of protocols. Many of these programs share some similarities of content, but they also differentiate themselves in certain areas. Just as there are numerous fitting schools, there are numerous fitting tools and equipment available to today’s bike fitters ranging from a simple plumb bob to 3D motion capture systems, power meters, and wind tunnels.

Jim at Cyclemetrix has attended not one, but several different fitting schools. This gives him a very broad base of knowledge in fitting techniques and protocol. That knowledge base, plus the experience gained by doing over 300 bike fits is what you get with a fit at CycleMetrix.

CycleMetrix has a dedicated, and well equipped fitting area, with the specialized equipment and necessary tools on hand to get the job done. We have over 100 stems, 50 saddles, and numerous seatposts, cleat wedges, handlebars and aerobars on hand to dial in your fit on your new or existing bike. We don’t have a wind tunnel….yet. But we can make arrangements to get you into one.

Bike fitting sessions usually last around 90-120 minutes depending on how much work has to be done. Follow-up with the rider is paramount in the days and weeks after the fit is complete. Some real ride time is often required to put a new position to the test and on occasion further minor adjustment may be necessary.

Shopping for a new bike and confused by a sales guy telling you need this size of bike and your friend’s telling you to buy that size of bike and then there was that article you read on the internet, which didn’t coincide with what either of them told you?? Have you studied the bicycle geometry charts until your head hurts and still can decide whether to buy a 54 with 54.5 top tube and a 13.7 head tube or a 55 with a 54.2 top tube and a 12.5 head tube???

Bikes have a multitude of geometries. Even though two road bikes are both classified by their respective manufacturer as being a “medium”, they could be vastly different in their geometric configurement. Change one part of the bikes geometry and you influence the entire bike and possibly the way it fits and the way it handles. A rider who is 5’9” tall may ride a medium in one brand of bike and a large in another brand.

If you need professional help deciding what size of bike you need to buy, Jim can help you regardless if you plan to buy your bike here or not. If you have a specific bike in mind, It helps a great deal if you know the make, model, and year of the bike and have a geometry chart for the bike.

Jim can also help you understand the differences between a road bike and a tri-bike, so that you can make an informed decision and get the bike that is right for you and your goals.

Retul is the most advanced bicycle fitting system available today. The system incorporates an amazingly precise three-dimensional motion capture technology, immediate report capability, and millimeter-specific digitizing tool to provide the most accurate dynamic fitting solution in the industry. 

Bicycle fitting is best measured during dynamic pedaling action. Static measurements tell the fitter very little about how the rider's body reacts and interacts in biomechanical motion. The Retul system reads the body in motion, in three dimensions. An observer watching a cyclist while pedaling cannot measure lateral, vertical and horizontal movement. The Retül system eliminates the guesswork and assumptive nature of fitting, providing the fitter with the most accurate data set available in bike fitting. The result is that the rider will have a true fit to his or her bike, maximizing efficiency and performance while avoiding discomfort or injury.

Objective, dynamic, and accurate data: This is the foundation of the Retül concept.
Every cyclist has unique biomechanics, therefore there are no generalizations that apply when truly fitting a rider to a bike. Purchasing a new bike can be both a fun and exciting experience, but riding a bike that is not properly fit can cause frustration, pain or injury, and ultimately causes the rider to put the bike in storage where it starts collecting dust.

Perhaps you already own a bike and your position is not optimized, causing you to underperform. A proper bike fit not only will provide you with the most economic means of expending energy, but will also prevent pain that is common in the knee, hip, and lower back, particularly with riders who are trying to adapt their bodies to the bike they already have purchased.

We would rather adapt a bike to the body you already have. There is a big difference between being sized for a bike and being fit for a bike. When it comes to the biomechanics o f fitting a rider to his or her bike, little ‘tweaks' can be very significant. Our mission is to spread this message to all fitters and cyclists alike. Whether a rider is on an $800 commuter bike or $8,000 performance race machine, a proper bike fit is as essential. Tools that help the fitter see accurate cycling-specific movements have become equally essential in providing quality assessments of a rider's bike positions.


Retül bike fit technology incorporates three main data points in fit theory:
Bike Fits Must be Dynamic
Most bike fitting specialists fit riders in a static position. This is because the traditional tools of the trade - tape measures and plumb bobs - do not allow accurate measurements while the rider is pedaling. Using motion capture technology, Retül records the rider's positions in motion, therefore creating the most realistic picture of the rider's actual pedal strokes and body positions when out on the road and trails.
Measurements Must be Accurate
Measurements made by traditional tools have one thing in common. They are subject to human error and therefore can be devastatingly inaccurate. Even slight inaccuracies can drastically change the rider's feel after a ride. The Retul system is accurate to within less than a millimeter, creating true objective data which can be utilized by the fitter for the perfect biomechanical fit.
Biomechanics are Best Assessed in Three-Dimensional Space
Fit data collected in a traditional two-dimensional plane (i.e. video-based systems) is fairly limited because the fitter can only look at one view at a time, and those views stand as independent reference points. In order to make the best fit recommendations, the fitter must realize that the front and side views are actually interdependent reference points. In other words, the front and side views must be viewed simultaneously in three dimensions in order to see how all the applicable movements of the body are working together. Retul uses a 3D motion sensor to simultaneously gatherdata on multiple angles of the rider.


  • The fitter does an initial physical assessment of the rider, and at this point can address the rider's concerns about performance, pain, or any other issues the rider hopes to alleviate during the bike fit. Once this is completed, the Retül process begins.
  • LED markers are strategically placed on eight anatomical points of the rider: the wrist, elbow, shoulder, hip, knee, ankle, heel, and toe.
  • As the rider pedals, Retul's sensor bar gathers real-time, three-dimensional data of the rider's pedal strokes and movements. Retül's rotating platform allows the fitter to collect data for both sides of the rider without the rider leaving the bike.
  • The rider's data is compiled into a reader-friendly report for analysis by the fitter. The fitter can then assess the rider's position and make necessary adjustments.
  • The Zin, Retul's handheld digitizer, allows the fitter to digitally measure the rider's bike at 13 to 15 points, depending on the bike. The Zin can measure fixed points, contours, and curves, and then provides a complete digital map of the bike.
  • The fit information is saved and stored on the fitter's computer. The data includes the rider's personal profile, specific data and measurements from the fit, bike measurements, and the rider's final fit position. The fitter will be able to access and print these records for comparison and distribution, and track historical fit data for the client.
