Bike Fitting

Let the experts at Zinn Cycles find your perfect fit!

Zinn Cycles is committed to providing athletes of all sizes with the opportunity to truly achieve the perfect fit on their bicycles. Cycling equipment availability is limited for many people, such as for those who are short, tall, or don’t have average proportions. Many people are also plagued with joint or back issues. Riding a bike that is designed to work optimally for your unique body is one of the best things you can do to reduce or prevent knee, neck, back, and other pain or discomfort. Cycling is an incredible form of exercise that is easy on the body if you’re using a properly fitting bicycle. We want to be sure that everyone can comfortably ride a bike for fun, exercise, or competition. Zinn Cycles offers the widest size range of crankscycling components and bicycle frames in the world to help optimize the fit of any bike. With a professional bike fitting, you can be sure that every part of your bike will be proportional to you no matter what those proportions are.

Gold Medal – Zinn/BUILD Medical fit

The Zinn/BUILD Bike Fit service is a comprehensive approach to optimizing your cycling position, with the aim of minimizing injury risk and improving performance and comfort on the bike. We start with an initial consultation and bike fit at Zinn Cycles with Lennard Zinn. Lennard will create a preliminary drawing of the bike and send to the fitter at build so they can set up their fit bike to the exact dimensions specified by Lennard. You will then begin your appointment at BUILD where the session begins by understanding the cyclist’s sport history, injuries, body mechanics, medical issues, and goals, followed by a comprehensive, cycling-specific physical therapy evaluation. On the bike, BUILD will utilize Retul 3D motion capture technology and analyze cycling dynamics and movement patterns. Based on the exam and analysis, the bike position is optimized for for your biomechanics and goals. Following the bike fit, Lennard will consult with the BUILD fitter and adjust your bike design accordingly. You will receive a report including position measurements, a better understanding of your body and bike position, and actionable steps to continue to improve on the bike.

RideLogic mountain bike fit with Nick Wigston

Bike geometry is essential to your success trail riding. We believe a bike design should allow you to really shred and also be comfortable on your bike. With a custom mountain bike fitting, you can ride aggressively all day long.

When the distance between your feet and the handlebars fits your body, you’ll feel more in sync with your bike. With the correct measurements, you can perfect the pumping motion and generate more power while pedaling, which is essential to body movement when mountain biking. Bikes that are too long or do not match the proportions of your body can reduce movement and hinder your ability to pump quickly over impediments, steer precisely in sharp turns, and navigate descents confidently.

Lee McCormack of Lee Likes Bikes has created the RideLogic™ fit system to deliver a simple yet effective strategy for selecting an ideal frame size and obtaining the perfect cockpit dimensions, so you can maximize your potential when riding. Far different from traditional mountain bike fitting methods, this is the first true shredder equation that allows riders to get their mountain bike perfectly fitted.

If you need assistance finding the perfect mountain bike for your size, we have been trained by Lee McCormack in the RideLogic fit system to get you fitting perfectly on any mountain bike. We offer personalized in-person fittings and can even construct a custom bicycle based on this geometry if necessary – guaranteeing that it fits perfectly with your body type. Contact us today to book an appointment.
