This rim stands out with its excellent strength-to-weight ratio, and in the SL version it is one of our best-selling MTB rims. In 2025, the rim received an innovative shape, with the main improvement being the bead, which was widened from 3 mm to 3.5 mm. This makes the rim highly durable while maintaining a low weight. Thanks to its low profile of 20 mm, the rim is also slightly „flexible“, which ultimately contributes to its durability.
Rims in the Super Light (SL) version combine low weight with high strength, making them a universal choice for demanding cyclists. Thanks to their optimized design, they offer an improved weight-to-stiffness ratio, enhancing performance when climbing and accelerating. They are an excellent choice for both sport and recreational riding. Rims in this version have a weight limit of 100 kg.

Sapim CX-Ray are among the lightest and strongest steel spokes on the market, making them an ideal choice for both racing and performance bikes. Their unique profile with a flattened center section significantly reduces aerodynamic drag without sacrificing strength or durability.
They are made from premium stainless steel, which provides excellent fatigue resistance. Despite their extremely low weight, CX-Rays maintain high tensile strength and torsional resistance, which contributes to the stiffness and long life of the spoke.
Compatible with most standard nipples and hubs, they are suitable for a wide range of applications – from road and triathlon bikes to MTB and gravel wheels. If you are looking for the best balance between weight, aerodynamics and reliability, Sapim CX-Rays are the clear choice.

Sapim Alu Double Square Secure Lock are top-of-the-line aluminum nipples designed for maximum spoke strength and stability. Thanks to their special double square profile design, they allow for more accurate centering and even distribution of spoke tension, which contributes to a longer wheel life.
The patented Secure Lock system prevents nipples from loosening spontaneously, helping to maintain spoke tension even under extreme loads. The low weight of the aluminum alloy contributes to the overall reduction of the bike's weight, which will be especially appreciated by racers and performance-oriented riders.
Thanks to their precise processing and high corrosion resistance, Sapim Alu Double Square Secure Lock nipples are an ideal choice for road, gravel and MTB bikes, where the emphasis is on low weight, strength and reliability of the spoke.
