Lenz Sport Bike Fit and Cockpit Setup

Bike Geometry is at the core of our designs. We have developed our unique geometry from years of BMX racing, mountain bike racing, trail riding, downhill racing, and cross country distance riding. We believe that a bike should be designed to shred trails, not simply to sit on the seat and pedal. Once you dial in a bike for aggressive riding, it will pedal just fine. The relationship between your feet and your handlebars is at the core of aggressive riding, and when we optimize that distance, you will feel at one with your bike. This is because it optimizes the most fundamental body movements of mountain biking, which is pumping. If your bike is too long, you won’t have the proper range of motion to aggressively pump over obstacles, carve fast corners, and handle steep descents. Lee McCormack at Lee Likes Bikes, has developed this fit system into a simple yet effective method to help you to choose the perfect frame size and get the perfect cockpit dimensions to optimize your ability to shred trails. As Lee says, Ride with a capital “R”. Lee has developed the RideLogic™ cockpit fit system to create a way of fitting a mountain bike to the rider that is not based on age old fit systems that came from road biking. RideLogic™ is the first true shredder’s formula for getting the ultimate fit on your mountain bike. Lenz Sport is the first bicycle manufacturer to use the RideLogic™ system to fit customers onto our bikes. You can submit a few measurements to us and we will tell you exactly which frame size, which stem length, handlebar width and height, and seat height needed for you to have the best cockpit and pedaling position. If you are ordering a complete bike, we will dial it in perfectly so you can hop on and Ride with a capital “R”. You can also use the RideLogic™ website to determine your own cockpit fit and we can set up your bike based on your requests.

Rider Area Distance

-RAD-

The Rider Area Distance, RAD, is the most important measurement for your bike to shred. It optimizes the distance between your feet and your hands for the best range of motion while pumping trails, carving corners, lofting over roots and rocks, and descending with stability and confidence. We can help you choose the best frame size to get the perfect RAD for you.

Rider Area Angle in Degrees (RAAD)

The next most important measurement is RAAD, Rider Area Angle in Degrees. This angle depends on the type of riding you are doing. The angle is bigger for DH and smaller for XC. Let us know your riding style and we will help dial your bike in perfectly.

Standover Height

We want to make sure that you have plenty of standover clearance on your bike. This is based on your inseam length. We design our bikes to have lot's of standover clearance so that we can focus on getting your RAD and RAAD perfect.

Seat Height

Last but not least, we use your inseam length to dial in your optimal seat height for pedaling. All Lenz bikes are designed to work with internally routed dropper posts, so you can drop your seat for everything but plain old pedaling.

Lenz Sport Geometry

We have been designing bikes around this concept since 1995. Devin Lenz grew up racing and riding BMX bikes, then he moved on to Mountain Bikes. He knew the importance of bike geometry and the relationship of feet and handlebars for ultimate riding. Now Lee has put this information into an easy-to-follow formula for us to figure out exactly what size frame, stem, cranks, and handlebars work best for each rider. At Lenz Sport, we have somewhat unique bike geometry as compared to other brands. Here is some information on our geometry and why we believe it’s best.

Compact frame: There is a major trend for super long bikes, and we believe that is counter to a good cockpit set up. If your bike is too long, you will not be able to get your RAD (rider area distance) short enough, and you will not be able to ride aggressively. We build our bikes to be compact and easy to get handlebars the right distance from your pedals for ultimate trail mobility and shredding. We build our frames with lots of standover clearance so that you can easily size up or down based on proper cockpit dimensions for your own body. Don’t be stuck on the labeled size, go off of the actual measurements.

Short Chainstays: Short chain stays are at the heart of our frame geometry. We boast some of the shortest chain stays on any bike on the market, which helps our bikes loft easily over obstacles, manual through rock gardens, and get clean jumps off of drops without feeling like the front end is trying to drop out below you. The short chain stays also help keep the wheelbase shorter for ultimate maneuverability through technical terrain.

Steep Seat Angle: Steep seat angles are great for climbing, and when combined with the short chain stays, makes a long travel bike a killer climber.

Slack Head Angle: We avoid steep head angles on our bikes, but we also don’t go crazy slack except on the downhill bikes. We want the bike to handle well on climbs and descents, so a 66 to 68 degree head angle is perfect for a trail bike. Much slacker than that and the bike will not climb well, and the wheel base will get so long you can’t maneuver very well.

Wheel Size: We believe everything on the bike should be proportional to the rider and riding style. That is why we offer all bikes in all wheel sizes, including the newer plus size tires, which roll fast and effortless over rough terrain.

About the RideLogic™ Bike Setup system

The RideLogic Bike Setup System evolved with the Lee Likes Bikes Teaching Method, which is the world’s simplest, most powerful and most scalable mountain bike and BMX curriculum. Over the past decade and a half, Lee has taught riding skills to thousands of riders of all styles and levels ( from road to cyclocross to BMX to cross county to enduro to downhill; beginner to expert to world champion), and he’s learned a ton about the ways bodies, bikes and trails interact. There comes a point when you can’t optimize technical riding skills without optimizing rider movement, and you can’t optimize rider movement without first optimizing bike setup.

Most bike fits are based on traditional road wisdom and a static riding position. They don’t consider the needs of riders who brake hard, carve corners, pump rocks, boost jumps and basically have more fun on their bikes. Those of us who like to shred — gravity racers, BMXers and modern trail riders — have always known shorter stems and taller bars tend help us handle our bikes better, but there was never any precise method to estimate out how short and how tall.

The RideLogic™ Bike Setup Method brings logic to the process of setting up your bike for Riding (active Riding with capital R, as opposed to passive riding with a lowercase r). RideLogic™ focuses on universal human movements (not just things you do on the bike). It unites the principles of biomechanics, kung fu riding technique and bicycle dynamics.

Maximum Range of Motion

The Rider Area Distance, RAD, is the most important
measurement for your bike to shred. It optimizes the distance between your feet and your hands for the best range of motion while pumping trails, carving corners, lofting over roots and rocks, and descending with stability and confidence. We can help you choose the best frame size to get the perfect RAD for you.

Maximum Torque

Torque is the key to sprinting, hopping, manualing, jumping and other power moves. This comes from having the correct distance between the feet and the hands. If your bike is too long, you will be pulling torque from your weaker arm muscles instead of your stronger core and glute muscles.

Four areas of bike fit

Rider Area Distance – RAD

The Rider Area Distance, RAD, is the most important
measurement for your bike to shred. It optimizes the distance between your feet and your hands for the best range of motion while pumping trails, carving corners, lofting over roots and rocks, and descending with stability and confidence. It allows maximum torque when getting up steep inclines, climbing ledges, powering off the starting line, and more. We can help you choose the best frame size to get the perfect RAD for you.

Rider Area Angle in Degrees – RAAD

The next most important measurement is RAAD, Rider Area Angle in Degrees. This angle depends on the type of riding you are doing. Once we figure out the RAD measurement, we adjust the Rider Area Angle to suit your riding style. We do this by adjusting the reach and rise of the stem and handlebar. So if you are an XC racer, the RAAD will be much lower than if you are a DH rider. For most of us trail riders, we will fall somewhere in between. Let us know your riding style and we will help dial your bike in perfectly.

Handlebar Width

Handlebars are getting wider, but is that actually better? We feel that handlebar width should be proportional to your size, specifically your shoulder width. That is why we have shoulder width as part of the measurements form. If you are of average proportions, we can figure out a good bar width based on your height, but if you want to get more exact, measure your shoulders. More accurately called your “biacromial width.” We are looking for the distance between the ends of your shoulder bones.

Standover and Seat Height

Last but not least, we use your inseam length to make sure you have ample standover clearance and to dial in your optimal seat height for pedaling. All Lenz bikes are designed to work with internally routed dropper posts, so you can drop your seat for everything but plain old pedaling. We use standard methods to calculate seat height since that is not affected by the other more important dimensions.

This is a link to a blog post from Lee Likes Bikes about sizing down. The RAD measurement is the most important measurement, so before a new bike, it’s important to dial in those measurements to make sure the bike is not too long or too short.
