MEB738S

Explore New Trails with Precision on Your MTB E-Bike

The MEB738S is a full carbon 27.5" rim with a symmetric 31mm deep profile and a 32mm inner width, specifically designed for ebike mountain bike riders. The carbon construction provides strength and durability, while the wide inner width allows for the use of wider tires for better traction and control on challenging terrain. The symmetric profile provides a balanced ride, and the rim is designed to handle the extra weight and power of ebikes.

Tire Interface

Hooked or crotchet refers to the shape of the rim flange. In this variant, the rim flange has a so-called hook. This supports the fixation of the tire bead and ensures safe function, also in high pressure use cases (>5 bar tire pressure). Tubeless refers to the ability of the rim to be used without a tube, but a tube set up is also possible.
HOOKLESS

Brake Interface

The reason for the trend towards disc brakes is a question of safety: disc brakes improve control. But what are the differences between disc and rim brake systems?

Rim Height

In cycling, rim height significantly impacts the aerodynamics, agility and weight of the wheel. The general principle is the higher the profile of the rim, the greater the aerodynamic advantage; the lower the profile of the rim, the greater the response and better the handling when cornering and changing speed.

Rim Inner Width

Tires with different widths and profiles are used depending on the surface. The choice of tire width for the respective purpose in road cycling results in a recommendation for the rim inner width.

Rim Diameter

The 700c (622 mm / 29 inches) is the most common wheel size for road racing. The 650b (584 mm / 27.5 inches) wheel size is used in specific areas. Each wheel size offers unique advantages for different kinds of riding.

E.R.D / Effective Rim Diameter

The Effective Rim Diameter is the diameter of the rim at the location where the spokes make contact when they're laced to the rim. This measurement is crucial for building wheels because it ensures that the spokes are the correct length to properly tension the wheel and maintain its strength and integrity.

 

Here's why E.R.D. is important:

  1. Spoke Length Calculation: When building a wheel, you need spokes that are the right length to connect the rim to the hub. The E.R.D. is used in the spoke length calculation formula to determine the exact length needed. Using the wrong spoke length can lead to an improperly tensioned wheel, which affects its durability and performance.

  2. Wheel Strength: Proper spoke tension is crucial for the overall strength and longevity of the wheel. If the spokes are too short or too long, it can lead to uneven tension, causing the wheel to be weaker and more prone to flexing or breaking under load.

  3. Wheel Trueing: When the spokes are the correct length, it becomes easier to true (align) the wheel properly, ensuring that it runs smoothly and without wobbling or rubbing against the brake pads.

  4. Compatibility: Knowing the E.R.D. of a rim is essential when choosing spokes and hub combinations. Different hubs and rims have varying dimensions, so having the correct E.R.D. ensures that all the components work together seamlessly.

To measure the E.R.D., you typically use a special tool called an E.R.D. gauge. This tool helps you find the exact point on the rim where the spokes will lie. Once you have the E.R.D. measurement, you can calculate the spoke lengths and build a strong, reliable wheel that's suitable for your specific bike and riding style.
