Sapim MG washers are special washers for spoke nipples, manufactured by Sapim. The washers are designed to be used between the nipple and the rim hole, offering numerous advantages, particularly with carbon rims or thin-walled rims. Unlike MS washers, MG washers are made of stainless steel using CNC machining, ensuring greater precision.
Here are some details about Sapim HM Washers:
– Purpose: They are used to increase the bearing surface area between the spoke head or nipple and the rim or hub flange, helping to prevent spoke head pull-through or damage to the rim/hub. This is especially useful with carbon rims or delicate materials.
– Material: Typically made from stainless steel for strength and corrosion resistance.
– Design: Flat, thin washers sized to fit under Sapim spoke heads or nipples. They are precision-made to ensure proper fit and function with Sapim components.
– Use Cases: Commonly applied in high-stress wheel builds, such as mountain biking, downhill, or wheels with oversized spoke holes.
If you are building wheels with Sapim spokes and need to use washers for reinforcement or protection, Sapim HM Washers are a trusted choice.
Sapim HM Washers are often recommended for use with carbon rims to provide additional protection and support where the spokes attach to the rim.
Here’s why and how they are used with carbon rims.
Purpose of HM Washers on Carbon Rims
– Protect Rim Material: Carbon rims have thinner or more delicate spoke holes compared to aluminum rims. HM Washers increase the contact area between the spoke head or nipple and the rim, reducing the risk of cracking or crushing the carbon material around the spoke holes.
– Distribute Load: They help distribute the tension load more evenly over a larger surface area, which is crucial in carbon rims to prevent damage.
– Prevent Pull-Through: They reduce the chance of the spoke head pulling through the rim hole under high tension.
Key Details
– Material: Stainless steel or sometimes aluminum (but stainless steel is more common for durability).
– Design: Flat, thin, precisely sized to fit under Sapim spoke heads or nipples.
– Compatibility: Made to match Sapim spokes and rims, but check your specific rim and spoke model for fit.
– Installation: Place the washer between the spoke head (or nipple, depending on the build) and the rim surface when assembling the wheel.
When to Use
– Highly recommended for carbon rims with large or thin spoke holes.
– Useful in high-tension wheel builds, such as road racing, mountain biking, or downhill.
– Often specified by carbon rim manufacturers as part of the wheel build guidelines.
If you are building or servicing wheels with carbon rims, using Sapim HM Washers is a good practice to enhance durability and safety.
