Wheels that push the boundaries of what's possible. This set is aimed squarely
at the top — extremely light, incredibly responsive, and incredibly fast. The
combination of UL carbon rims, legendary ultralight Extralite HyperBoost3 hubs,
and unique Berd PolyLight polymer spokes create a set that effortlessly gets
under one kilogram.
The result is a bike that accelerates instantly, responds to every move, and surprises with subtle micro-vibration damping. Berd spokes give the ride a lightness and smoothness that you won't experience with metal spokes — ideal for XC racing, hilly marathons, and fast trail crossings.
Precision CNC-machined Extralite hubs ensure maximum stiffness and a perfectly smooth ride, UL rims give the whole set explosive response, and minimal rotational mass takes pedaling efficiency to a whole new level.
A set for riders who want the best — the lightest, fastest, and most exclusive. If you're looking for bikes without compromise, this is the world league.
These are the lightest MTB rims with an internal width of 30 mm in our offer! Thanks to the low height of 20 mm, this rim profile is a bit "more flexible" and therefore relatively tough. If you want to build top light carbon wheels with super riding characteristics, this is the rim for you! But beware of the weight limit and the overall slightly lower resistance...
The rims in the Ultra Light (UL) version are designed for cyclists who are looking for maximum weight savings without compromising on strength and performance. Thanks to the use of premium carbon fibers and innovative manufacturing technologies, these rims are extremely light and ideal for racing use on flat and hilly tracks. The perfect choice for road races, time trials and mountain stages. The rims in this version have a weight limit of 90 kg.

Extralite HyperBoost 3 Front is an extremely lightweight front hub designed for modern MTB bikes in the Boost 15×110 mm standard. With a weight of only 74 grams, it is one of the lightest on the market, while maintaining exceptional stiffness and precision processing. The hub body is made of high-strength 7075 TXX aluminum alloy and uses straight-pull spokes, which ensure optimal power transfer and uniform spoke tension. The bearings are precisely mounted in the axle with micro-adjustment of clearance using the Micro-Tuner system, which contributes to smooth operation and long service life. Extralite uses sophisticated seals with O-rings and 2RS bearings, which effectively protect against dust and moisture. This hub is designed for racing use in XC and marathon, where every gram counts. It stands out for its precision Italian manufacturing, top-notch rigidity and unique combination of minimal weight with maximum efficiency.

Berd PolyLight are some of the lightest spokes on the market. They are made of an advanced polymer material that offers an unbeatable weight-to-strength and vibration damping ratio. Compared to traditional steel spokes, they are up to 50% lighter, while maintaining exceptional tensile strength and high fatigue resistance. Thanks to their design, they significantly reduce the rotational weight of the wheel, which will be appreciated by road and MTB racers, as well as demanding hobby riders.
Berd PolyLight spokes bring increased riding comfort, as the polymer material effectively absorbs micro-vibrations from the terrain. They are resistant to corrosion and chemicals and do not require any special maintenance. Each spoke is handmade in the USA with an emphasis on precision and quality. They are compatible with most common hubs and rims and are an ideal choice for those looking to take their bike's performance to the next level.

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.
