CUTTING-EDGE TECHNOLOGY TO ENHANCE DURABILITY AND SPEED
In road cycling and fast gravel, where every watt counts and mechanical reliability is crucial, bearings are no longer a secondary component but have become a key element of performance. Reduced friction, smooth rotation, and resistance to moisture and dirt now make all the difference in increasingly demanding disciplines.
In this context, ISB SPORT continues to strengthen its position in the premium segment with the Endurance BO LC/NC range, a technological evolution developed specifically for road and fast gravel bikes, where speed and durability must coexist in balance.
The Italian company, which specializes in high-performance cycling solutions, maintains a strategy clearly focused on innovation, engineering, and the constant expansion of its product catalog. The goal: to offer products that undergo strict quality controls and are capable of meeting the real needs of today’s market.
An evolution designed to ride faster… for longer
The new Endurance BO series stems from the development of ISB SPORT’s wheel bearings and represents a significant leap forward in quality within the brand’s lineup. Its main innovation lies in the combination of technologies aimed at simultaneously improving:
- corrosion resistance
- smoothness of rotation
- rotational speed
- bearing lifespan
The result is a product designed for cyclists seeking maximum mechanical efficiency on both road and fast gravel, disciplines where high speeds and constant exposure to dust, water, or weather changes demand increasingly sophisticated components.
LC/NC SEALING: SMART PROTECTION WITH MINIMAL FRICTION
One of the most interesting features of this line is the new combined LC/NC sealing system, developed by ISB SPORT to optimize the balance between protection and performance. The brand visually distinguishes the two seals using specific colors, making them easy to identify and install.
This hybrid configuration allows for a combination of:
- effective protection
- lower mechanical resistance
- a smoother and more efficient ride
LC (Light Contact) outer seal – green
The outer seal features an NBR rubber lip that makes light contact with the inner ring. This design provides excellent protection against external contaminants while maintaining minimal friction, which is particularly important for high-performance road and gravel bikes.
NC (No Contact) inner seal – black
A low-friction, non-contact seal is used on the inside, designed to operate at high rotational speeds without generating additional resistance. The goal is to maximize the smoothness and rotational capacity of the assembly.
BLACK OXIDE COATING: THE KEY TO GREATER CORROSION RESISTANCE
Another distinguishing feature of the range is the BO (Black Oxide) treatment applied to the steel rings. This chemical treatment creates a protective anti-rust layer that significantly improves corrosion resistance, especially on the surface layers of the outer ring. As a result, ISB SPORT achieves very high protection against moisture, sweat, and harsh environments, approaching the performance of stainless steel without compromising the bearing’s dynamic performance.
For road and gravel riders who train or compete year-round, this improvement represents significant added value in terms of maintenance and durability.
POLYAMIDE CAGE: LIGHTWEIGHT AND IMPROVED DYNAMICS
The new Endurance BO series also features cages made of polyamide, a material that offers both dynamic and structural advantages.
In addition to reducing the overall weight, polyamide helps minimize vibrations during operation thanks to its natural absorption and elasticity. This results in more precise ball guidance and smoother operation even under heavy loads or at high speeds.
TECHNOLOGY APPLIED TO REAL-WORLD PERFORMANCE
With this new generation of bearings, ISB SPORT demonstrates its commitment to continuing to evolve within the realm of high-performance cycling, offering increasingly specialized solutions for each discipline.
The Endurance BO LC/NC range is clearly designed for cyclists in the following categories: road, fast gravel, gran fondo, intensive training, and competition, who seek to combine low friction, maximum smoothness, corrosion protection, and a long service life.
One of the strategic pillars of the ISB SPORT brand is its alignment with market needs, characterized by continuous investment in engineering, R&D, and product line expansion, with the goal of offering the cycling industry a high-performance, quality-controlled product, where every step of the production process is subject to strict protocols to ensure absolute reliability.
ISB SPORT’s new Endurance BO wheel bearing range is an innovation that is here to stay and represents a step forward for the Italian brand, thanks to its specialization in combined seals designed to meet the needs of different disciplines: the magenta Full Contact bearings for MTB and gravel, and the green Light Contact bearings—which we are introducing here—for road and fast gravel.
A technological offering that confirms the growing importance of bearings in the overall performance of the modern bicycle and is available at Official Distributors, as well as in specialty shops and workshops.
