This rim stands out for its excellent weight-to-strength ratio and in the SL version it is one of our best-selling MTB rims. In 2025, this rim has an innovative shape and the main improvement is the bead, which has been widened from 3 mm to 3.5 mm, making the rim very durable while maintaining a low weight. Thanks to the low height of 20 mm, this rim is also a bit "flexible", which consequently contributes to its durability.
The rims in the Super Light (SL) version combine low weight with high strength, making them a universal choice for demanding cyclists. Thanks to the optimized design, they provide a better weight-to-stiffness ratio, which increases performance when climbing and accelerating. A great solution for both sports and recreational riding. The 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. Thanks to their unique profile with a flattened central section, they significantly reduce aerodynamic drag without losing strength or durability.
They are made of premium stainless steel, which ensures excellent fatigue resistance. Despite their extremely low weight, CX-Rays retain high tensile strength and torsional resistance, which contributes to the stiffness and long life of the spoke.
Thanks to their compatibility 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 construction with a double square profile, they allow for more precise centering and even distribution of spoke tension, which contributes to a longer wheel life.
The patented Secure Lock system prevents nipples from loosening spontaneously, which helps maintain spoke tension even under extreme loads. The low weight of the aluminum alloy contributes to the overall reduction of the wheel's weight, which will be appreciated especially by racers and performance-oriented riders.
Thanks to their precise processing and high corrosion resistance, Sapim Alu Double Square Secure Lock nipples are the ideal choice for road, gravel and MTB bikes, where the emphasis is on low weight, strength, and reliability of the spoke.
