Fittings



At ISFiTTlabs, we work by appointment only in order to maintain a thorough, high-quality service. We are committed to providing the best bicycle fitting experience available and take special care to ensure that you get the most out of your session. You should arrive for your fit in your cycling wear (no baggie shorts). It is important that you bring both your helmet and shoes.
Upon arrival, we will begin measurements. This will be comprehensive and be geared at discovering any body discrepancies and flexibility limitations. Once we know your particularities we apply this knowledge to the bike. At this point you will be asked to mount your bike (which is connected to a trainer). We will affix velcro tabs to your body to allow the infared to give educated information for us to apply to provide the best possible fit for you to your bike. (Hyperlink which reads [More Detailed Information on Fitts] that leads to the information in Tab B listed below)


*Please remember to bring the following items when you come for your fitting:
  • bicycle
  • pair of cycling shorts, (no baggies!)
  • current cycling shoes
  • sleeveless top, or cycling jersey that will not move excessively
  • socks that don't cover your ankle bone (typically a normal short tight cycling sock will work)
  • small sweat towel. YES, you'll probably break a sweat once, or twice...


Fittings can sometimes run long, it is advised you bring a small snack to ward off fatigue.


Please do NOT apply lotion or sunscreen prior to your fit. The dots for our Retul system will not adhere to your skin if you do.



*Possible Additional Charges:
Sometimes to achieve the optimal bike fit you may need some additional or different components. If this is the case, additional parts will be 10% off.

  • Stems - The majority of fits result in a stem change
  • Saddles – The saddle is often a major part of achieving your optimal bike fit. We have many different saddles for purchase or demo, including Adamo, Terry, Cobb, Fizik, Selle Italia, ism, and many others...
  • Handlebars/Aero bars- We may need to change your handlebars due to shoulder width, sacrum angle, desired reach, etc. We have access to many options if this is necessary
  • Seat post- A possible seat post swap may be needed depending upon your desired reach, saddle height, and knee fore/aft position
  • Wedges-We may install wedges under your cleat. This small change can have a big impact on your fit
  • Shims – Few leg-length discrepancies require shimming, but it is possible



Labor performed after the fit is an additional charge. This includes changing handlebars, re-taping bars, changing cranks, etc...

**A $50 deposit is required in order to reserve a fitting session. After you select your time slot you´ll be directed to pay the deposit fee through PayPal. All major credit cards are accepted. The remainder of your fitting balance will be charged upon completion of your fitting with ISFiTTLabs. Please be courteous regarding cancellations. Less than 48 hours notice will causes other riders to miss out on what would otherwise be an open fitting session. No-shows will forfeit their deposit. Please plan your schedule accordingly.

ISFiTTLabs is a dedicated fitting studio that has developed it's own in-house practices based on industry leading protocols to generate the most optimum, effective and dynamic bike fit for any type of cyclist. This process re-defines what a bike fitting is. We spend every day applying, testing and trying to improve the science, and the full range of components available to create the best fitting experience for any cyclist. We treat every fit with attention to detail that all our customers expect. This creates an evolving holistic and dynamic process. We believe any cyclist no matter what their experience or what bike they ride will gain in performance, health, and enjoyment from a correctly executed fit. A professional bike fit is the true foundation for providing a more pain-free, efficient and enduring experience on your bike. Simply put, a proper bike fitting should have the effect of making you forget about the bike and allow you to focus on the ride.
Even if you are not sure of the value and are hesitant about the involvement of a professional bike fit, it is probably true that you feel you could always get a little more juice or ergonomic comfort from riding the bike. This can only be realized with an optimum bike fit. ISFiTTLabs has developed an approach to fit that is truly unique and our success in fitting is reflected in providing the cyclist the knowledge of how to ride their bike more efficiently and to be fit on their bike enabling them to exploit their strengths and overcome weaknesses. Comfort and performance are increased and there is an accompanying reduced risk of chronic and acute injury.
We will never sell you a bike, but we will always help you find the right one regardless of brand, and if you have a bike already we will make it a simple extension of your body. Our fitting will supplement the effective adaptations conjured from structured training regardless of whether you are a competitive elite rider or a novice rider (or anything in between). We will fit you no matter what kind of riding you are doing. Our goal will always be the same for every type of cyclist elite to novice; making sure that you feel great every time you swing your leg over the saddle.
ISFiTTLabs was designed from the ground up to be the most technically advanced bicycle fitting studio dedicated to enhancing the bicycle fitting experience for all cyclists. By taking established fitting solutions and improving their functionality, we are able to make our fitting more precise than ever. This unique environment allows us to take fitting to a completely different level.

We understand that your time is valuable. We feel that its important for you to know a few basic, but crucial concepts regarding your pedal stroke. Please take time to read the following information and we know it will increase your perspective on what we do!

The lower extremity is dedicated to the vital tasks of weight bearing and ambulating; its health is essential to normal and efficient daily functioning. The same holds true for your pedal stroke. Any obvious deformity of the extremity may affect your pedal stroke! The ankle joint consists of three bones, the medial (inside) malleolus (distal end of the tibia), the lateral (outside) malleolus (distal end of the fibula) and the wedge shaped talus. The ankle gets its stability from the three bones, ligaments and tendons that surround the joint.

Foot Picture
The structure of the foot is determined by bones of the tarsal and metatarsals (forefoot). These bones form the arches of the foot which are also supported by many ligaments and tendons. It is know that a (high arched foot tends to be very rigid) and not very good at absorbing shocks through the foot. The (flat foot is also poor at shock absorption because it collapses) during contact. Providing longitudinal arch support for both of these configurations can make a difference since you only make contact at a very small area of the pedal.

Knee Picture
The knee is the largest synovial joint in the body. It involves three bones: femur, tibia and the patella and it should remain flexed during all components of the pedal stroke. The meniscus is a special type of connective tissue that provides shock absorption and increase contact surface at the knee joint. The knee joint relies primarily on ligaments for stability, sideways, forward or backwards and also rotational stability. The strongest muscles in the body, the quadriceps (thigh) muscles cross the knee and attach onto the tibia (tibial tubercle) to extend the knee. The hamstring muscles cross the knee joint at the back and function to flex the knee. Medial and lateral rotation can only occur when the leg is flexed. Perfect alignment is needed to protect this joint from excessive movement.

The pelvis and trunk shift laterally approximately one inch to the weight-bearing side during normal gait to center the weight over the hip. This movement is also needed as your in the saddle. By having a saddle too high, you reduce this needed lateral movement. The average length of a step is approximately 15 inches. With pain, advancing age, fatigue, or problems of the lower extremity, the length of steps may decrease. The same is true for the pedal stroke. e.g. 175mm cranks times 2 equals about 14 inches. A smaller crank can reduce stress on the lower extremity for any of the above reasons. The average adult walks at a cadence of approx. 90 to 120 steps per minute. This holds true for your pedal stroke! Changes in this smooth, coordinated pattern markedly reduce efficiency and greatly increase the energy cost. With advancing age, fatigue, the number of steps per minute decreases.

During the swing phase, the pelvis rotates 40-degrees forward, while the hip joint on the opposite extremity ( which is in stance phase) acts as the fulcrum for rotation. Having the wrong location of saddle can reduce this needed rotation movement.

Foot Picture
The dorsiflexors of the foot (the tibialis anterior, extensor digitorum longus, and extensor hallucis longus) permit the foot to move into plantar flexion through eccentric elongation so that the foot flattens smoothly. The wrong pedal stroke can cause the eccentric elongation of any of these muscles to be torn. Eccentric elongation is when you for the most part tear your muscles. This also affect your timing.

At mid stance, the foot weight is borne evenly on all aspects of the foot. Those with fallen transverse arches of the forefoot may develop painful calluses over the metatarsal heads. Any rubbing against the shoe can cause "Corns". A footbed helps spread the foot weight evenly on all aspects of the foot. It also helps hold the foot where it should be within the pedal stroke. A poor fitting shoe will cause you problems.

The toes need to grip the ground. Without a custom footbed you can't do this. Knee, the quadriceps muscles contract to hold the knee stable, since it is not normally straight. Weakened quadriceps may result in excessive flexion and a relatively unstable knee. Having a saddle too far forward causes a unstable knee. And having a saddle too low can cause unneeded wear. The knee is susceptible to injury primarily because it is subject to maximum stress, located as it is at the end of two long lever arms, the tibia and the femur. It is not protected by layers of fat or muscle and it is exposed both environmentally and anatomically, which contributes to its high incidence of injury. The bony contours of the knee are prominent and easy to find!

Acceleration
  • Foot: The dorisflexors of the ankle are active during the entire swing phase. They help shorten the extremity so that it can clear the ground by holding the ankle neutral.
  • Knee: The knee reaches its maximum degree of flexion between toe-off and mid swing, approximately 65-degrees. It further serves to shorten the extremity so that it can clear the ground.
  • Hip: The quadriceps muscle begins to contract just before toe-off to help initiate the forward swing of the leg. If one has poor quadriceps strength, he may rotate the pelvis anteriorly in an exaggerated motion to provide forward thrust for the leg.
Decelaration
  • Knee: The hamstring muscles contract to slow down the swing just prior to heel strike so that the heel can strike the ground quietly in a controlled motion. If the hamstrings are weak, heel strike may be excessively harsh, causing thickening of the heel pad, and the knee may hyper extend.
Instability
  • People who have dislocating knee caps have unstable knees.
  • People who have torn menisci have unstable knees which may buckle.
  • People who have torn collateral ligaments have unstable knees which may buckle. If you have any of the above issues, you should see a professional (e.g. a skilled physician or physical therapists).
  • The foot and ankle are the focal points to which your pedal stroke is transmitted. Supporting the entire foot reduces wasted movement. A perfect cleat placement is integrated with the entire lower extremity. It allows you to pedal better and absorb shock coming from the road. The perfect cleat placement also allows you to reduce numb feet. This involves longitudinal and lateral cleat placement unique to each person.


Just like hitting a golf ball, perfect alignment is key!!!
