Designed for the discerning cyclist who demands reliability and efficiency, this component is the heart of a robust and silent drivetrain. Whether you are navigating busy city streets, commuting daily, or exploring light trails, the Efficient Zumba provides a ´fit and forget´ solution that lets you focus on the joy of the ride. Its exceptional build quality makes it a prime choice for high-performance Urban Cycling and trekking applications.At its core, the THUN Efficient Zumba delivers unparalleled rotation quality thanks to its precision-engineered, double-sealed industrial bearings. This advanced design minimizes friction, ensuring that every watt of your power is transferred directly to the drivetrain for a more responsive and efficient ride. Engineered to withstand the rigors of daily use in any environment, this bottom bracket is completely weatherproof and maintenance-free. Its remarkable durability stems from a specially hardened axle material, fortified with THUN´s proprietary ML treatment, which offers superior resistance to wear and torsional forces. This commitment to strength is certified by its compliance with the rigorous ISO 4210-8:2014 standard for Mountain Bikes (MTB), guaranteeing safety and resilience under pressure.This bottom bracket is meticulously designed for modern bicycle builds. It is fully compatible with Gates CDN belt drive systems, making it the perfect foundation for a quiet, clean, and low-maintenance setup. A key innovation is the protective zinc-coated steel sleeve, which not only shields the internal bearings from contamination but is also perfectly suited for bikes with internal cable routing, allowing for a clean and uncluttered frame aesthetic. The left side features a functional shoulder (FS) for precise, stable installation, ensuring perfect bearing alignment and extending the component´s service life. With its BSA threading and square taper interface, it offers broad compatibility with a wide range of cranksets and frames.Assembly Advice: For optimal performance and longevity, follow the manufacturer´s recommended torque settings. The thread adapter tightening torque is 25-30Nm (assemble without grease), and the screw tightening torque is 45Nm.---Technical Specifications:* Design: Square Taper (4-edge)* Axle Standard: ISO* Axle Length: 120.0 mm* Axle Type: Special Hardened Steel (ML Treatment)* Bottom Bracket Housing: BSA (1.375x24)* Bottom Bracket Housing Width: 68 mm* Bearing: Double Sealed Cartridge (Industrielager)* Material: Steel* Compatibility: Gates CDN Belt Drive Systems* Certification: ISO 4210-8:2014 (MTB)
