Round washers (RW) have a simple function: they increase rim strength at the point of tension without increasing weight or altering spoke length. Their flat, thin shape deforms and adapts to the inside of narrow-walled rims, increasing the contact surface of the spoke nipple on the rim, shifting the stress away from the spoke hole and dissipating it over a larger area. This increases the strength and lifespan of carbon rims with delamination at the spoke holes.Format in a bag of 100 units.

BERD Spokes Bicycle SpokesBERD Spokes represent a radical evolution from traditional metal spokes. Manufactured from ultra-high-performance polymer fibers, they offer a unique combination of extreme lightness, vibration absorption, and structural strength, redefining the dynamic behavior of the wheel.Each spoke consists of a core of braided synthetic fibers with a tensile strength superior to stainless steel, encapsulated and finished using a patented anchoring system compatible with standard hubs and rims. This design eliminates the flex fatigue typical of metal and improves long-term durability.Main technical features:Weight reduction: up to 50% lighter than conventional steel spokes, allowing for more responsive and efficient wheels.High tensile strength: comparable to or better than high-end metal spokes.Vibration absorption: the polymer structure reduces micro-impacts, increasing comfort and control, especially in gravel and MTB.Optimized dynamic behavior: improves traction, stability and terrain reading.Corrosion resistance: insensitive to moisture, salt and chemical agents.Superior durability: no plastic deformation or fatigue from repeated cycles.BERD Spokes are especially suited for high-performance wheels in disciplines such as MTB, gravel, road and endurance use, where every gram counts and control over the terrain makes the difference.The result is a lighter, more comfortable and more precise wheel, designed for cyclists seeking maximum performance without compromise.

In steel spokes, CX'-Sprint is the reinforced version of the CX-Ray spoke.Aero spoke with a 1.2-2.3 mm flat section. Cold-forged for increased toughness and strength. Its flat center section, aerodynamics, shock absorption, and durability make it the preferred racing spoke for heavier riders, extra-strong wheels, or sprinters.Reference weight of 5.3 grams for a length of 260 mm.Profile: Aero oval increased by 1.2 mm / 2.3 mm.Weight: 5.3 grams for a length of 260 mm.Head: J-Bent or Straight-PullProperties: Aerodynamic, high fatigue strength, excellent stiffness and aerodynamics.Recommended use: High-performance and competition wheels for cyclists over 80 kg.

Straight screwdriver for 3.4 mm square heads. Adjustable length for rims up to 88 mm profile.The handle has "quarter turn" markings for greater precision in adjustment.

Sapim hex collet wrench for 5.5mm collets.

Practical help during the construction of wheels. The Sapim clamping screwdriver for easy positioning and fixing of nipples on high profile rims.

This spoke wrench is suitable for holding CX, Delta, and CX-Ray flat spokes. With different grooves on its outer side for various spoke diameters between 0.9, 1.1, 1.3, and 1.5 mm, it allows you to hold the middle of the flat spokes while handling them during installation, preventing them from twisting and becoming damaged, and increasing the accuracy of the work. Nothing is worse than a wheel with flat spokes twisted together, as it indicates poor workmanship and greatly increases the chances of breakage.

Ruler for measuring the length of spokes/heads.

Drift screwdriver for Standard "long" nipples (high rims).This tool allows for quick adjustment of straight-spline threaded heads to their threaded stop. Ideal for ensuring uniform adjustment of all heads prior to centering and stabilization.Suitable for rims with a profile up to 50 mm.

Sapim Hexagonal Nipple Key for 5,5mm nipples.

Professional "square" spoke wrench for 3.45mm nipples (STD)

Professional "square" spoke wrench for 3.45mm nipples (STD)

SAPIM analog sphygmomanometer. Mitutoyo precision.

The Secure Lock system is a mechanical locking mechanism that prevents the spokes from loosening. Nipples for spokes with 2.3mm threads (13g).

HM washers reduce friction between the nipples and the rim during the mounting process. This allows for greater tension with less effort and increased precision. If you aim to provide high-quality tires for your clients, then you need to work with this product.

Spoke washers help to better adjust the hub's flex and dynamic oscillation. Their use is recommended for hubs with narrow flanges or dilated holes. These washers are placed on the spoke head before insertion into the hub, providing better retention of the spoke in the hole itself and preventing "hammering" and premature breakage caused by spoke oscillation on the hub. While not essential for wheels with all components properly designed or selected, they are very useful for addressing problems with spoke bends caused by dilated hub holes or hub flanges that are too thin or unstable under high load.Format in a bag of 100 units.

The 13G nipples indicate a metric thread diameter of 2.3 mm, suitable for high load wheels and of course only compatible with 13G threaded spokes.Made of brass with a black oxide anti-corrosion treatment. Nipples only compatible with spokes with 2.3 mm (13g) threads.Nipples compatible with aluminum rims with standard 4.5 mm diameter holes.

The head works like a ball joint. For a better line of fire with the spokes.
