Compatible with: Frame: BSA Frame width: 68 – 73 mm Cranksets: Sram dub Included spacers: 1x1mm / 1x2mm / 1 2.5mm / 2 4.5mm / 2x1mm o-ring Technologies DualCupTechDualCupTech automatically aligns the bearing surfaces regardless of external factors. Alignment between the bearings on both sides is crucial, and the manufacturing process pays special attention to minimizing this concentricity value. The result is incredible: an extremely smooth pedal stroke from day one. DualCupTech not only self-aligns the bearings but also creates a solid central joint without requiring threading or one-piece design. After assembly, the bottom bracket functions as a solid piece and eliminates any noise or movement issues. DualCupTech can be installed and removed like any other bottom bracket, without the need for special tools or complex instructions. Ceramic ball bearingsExperienced manufacturer of high-performance bearings. Ceramic ball bearings offer superior corrosion resistance, greater dimensional stability, lower density, and higher heat resistance. All this results in a more efficient material for bottom brackets. Fully sealedEvery dust particle or drop of water is a potential cause of noise or bearing wear. That’s why all bottom brackets come with up to five O-rings to keep dust, water, mud, and moisture out of the bottom bracket. Axial sealsAll bearings are equipped with not one but TWO seals to protect against dust and moisture. This section is essential to ensure maximum durability and performance of the bottom bracket. 7075-T6 aluminumAerospace quality and precision in one of the strongest alloys. Additionally, Bikone has developed a matte anodizing that is particularly scratch-resistant, with a finish worthy of any art gallery. T6 heat treatmentFor most aluminum alloys: 6061, 6063, and 7075, the best heat treatment is T6. The T6 heat treatment ensures greater hardness and other mechanical properties, such as grain structure normalization. This guarantees that all aluminum products perform perfectly throughout their lifespan. Cost: $25 Free Shipping: We offer free shipping on orders over $30.
