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.

RSH SERIES' ADVANTAGES

The RSH series of tubular and clincher rims are a high-quality option for cyclists looking for reliable, lightweight, and aerodynamic rims for their road bikes. With options ranging from 33mm to 88mm deep, and widths ranging from 19mm to 25mm, there is a rim in this series for a variety of riders and riding styles.

These rims are constructed with high-quality carbon fiber, and feature a symmetric profile design for even distribution of forces, which enhances stability and handling. The rims also have a high-temperature epoxy to resist heat from braking, which extends the lifespan of the rim.

The clincher models in this series have an aerodynamic profile and are compatible with rim brakes, while the tubular models have a wider profile for increased stability and are compatible with both rim and disc brakes.

Overall, the RSH series of tubular and clincher rims are a great option for cyclists looking for high-quality, lightweight, and aerodynamic rims that can enhance their riding experience.
