Bicycles for tall guys – Professional bike fitting

Bicycles for tall guys are hard to find. Cycling is one of the best forms of cross training for basketball players because it is an exceptional workout and it is easy on the body and joints. Tall athletes often have knee and other joint issues, and running only aggravates those issues. Cycling for cross training will help professional basketball players to keep their bodies in top shape for a long career and prevent knee and joint issues in the future. It is typically very difficult to find a bike that will work for a pro ball player. Most production bikes are only made for people up to 6’2″, and most basketball players are over 6’6″. Many are over 7 feet tall. Zinn Cycles is the only company in the world that specializes in building bicycles for tall guys, and we have made many bikes for pro ball players from all over the world. For road bikes, mountain bikes, and travel bikes, Zinn Cycles sets the standard for tall athletes. Zinn Cycles has teamed up with Andy Pruitt to provide basketball players with the opportunity to truly achieve the perfect fit on their bicycles. Many athletes are plagued with joint or back issues while cycling, and getting a bike that is designed to work optimally for your body is one of the best things you can do to reduce or prevent knee, neck, back, and other pain or discomfort.

RETUL World Headqaurters

Without equal in his work with elite athletes, Dr. Pruitt has been taking care of some of the world’s best cyclists, triathletes, skiers, runners, and climbers since the 1970s. He created the Boulder Center for Sports Medicine to offer the kind of care and services that heretofore had been available only to professional athletes. Pruitt pioneered the use of high-speed video-capture technology in bike fitting decades ago and has been refining the science of 3D bike fit ever since. His book, Andy Pruitt’s Medical Guide for Cyclists is the bible for those seeking peak performance on the bike. After his retirement from BCSM, he is now heading up the bike fitting program at the new RETUL World Headquarters.
Nearly half of the world’s top-tier professional cycling teams depend on Pruitt to fly to Europe and fit their riders to their team bikes and work with them on positioning nuances on the velodrome or on the cobbles of Paris-Roubaix to find every bit of speed possible. It has become commonplace that the podium at the end of the Tour de France or Paris-Roubaix is composed of riders that Pruitt has set up on their bicycles.
Many professional bike fitters, Lennard Zinn included, are very good at optimizing a rider’s position in the X-Y plane (i.e., from the side, including saddle height and fore-aft, crank length, and handlebar reach and drop). However, dialing in the rider’s third dimension, the Z-plane, is the area that Andy Pruitt pioneered and continues to be the world leader in. The tracking of the knee, pedaling stance width, and the inward/outward tip (supination/pronation) of the foot on the pedal are critical to power output and injury prevention, and nobody adjusts these variables better than Pruitt and his team. These corrections also improve the rider’s position in the X-Y plane.
The RETUL 3D Fit always includes electronic data capture of the rider before and after on the bike. When required, staff will digitize the motion of the hips, legs, and feet during pedaling using the high-speed Infrared 3D Vicon Motus video-capture motion-analysis system.
The resulting moving stick diagrams on the computer screen show tracking of the hips, knees and feet in three dimensions in space. RETUL staff makes precise corrections to the shoes, saddle and handlebars where needed to optimize the tracking of the joints, and the rider can observe on the computer screen the difference between his or her optimized and initial pedaling motion.

Example of electronic joint tracings from the side view.

As designer of the Specialized Body Geometry shoe system as well as working in conjunction with Dr. Roger Minkow on the development of Specialized Body Geometry saddles and grips, Pruitt seemingly works magic with how the rider is supported on the saddle, in their shoes, and on their handlebar. This also corrects problems in the X-Y plane; a bike fitter can work all they want at getting a rider to look good on the bike from the side, but if the rider is not sitting on the correct shape saddle that is properly fitted to them and has his or her feet and hands supported properly, his or her efforts will be in vain. Without the prober support at the butt, feet, and hands, the rider will be lacking in comfort and efficiency, will be inviting injury, and will never look great on the bike from any angle.
Since you have probably not witnessed (as we have) cyclists who are already champions with years of trophies on their shelves suddenly produce 25 Watts or more of additional power (at lactate threshold) and get instant relief of pain that they have suffered with on the bike for years after a session or two at BCSM, it may be hard to understand how powerful Pruitt’s work is. We have seen it over and over again in working with Pruitt and his highly-trained team, and the dramatic change in position, pedaling dynamics, and power output on the bike is as magical as the broad smile on the rider’s face.

What we offer

We understand how busy it can be as a pro athlete, so we are here to accommodate you at any level that you need. We will handle all the details of the fitting and bike building process. Our staff will schedule all of your fitting appointments for you based on your requested dates. When you come to Boulder, we can arrange appropriate transportation to get you from the airport to RETUL World Headquarters for your 3D fitting appointment. Lennard Zinn, the owner and mastermind of Zinn Cycles, will meet you at RETUL with several demo bikes to ride, and he will help you figure out the exact type of bike you need.

The Process

  1. Zinn Cycles will schedule a 3D fitting with Dr. Andy Pruitt for you, on your preferred dates.
  2. At your fitting, Lennard Zinn will help you decide the details of the bike.
  3. Lennard will design your bike based on your initial 3D fitting with Dr. Pruitt.
  4. He will also take into account any special requests that you have for your riding position.
  5. Once the frame is designed, you will receive a CAD drawing of the bike.
  6. Upon approval, the frame will go into production.
  7. We will work directly with you to list out every component on the bike, and make sure everything is the way you want it.
  8. When the bike is ready, we will either deliver it to RETUL for your final fitting appointment, where Lennard Zinn and Dr. Andy Pruitt will work together to fit you on your bike.
