Industry Nine Torch Boost End Cap Kit
The Industry Nine Torch Boost end cap kit brings the brand's trademark high-precision machining, lightweight construction and bold anodized finishes to Boost conversions, delivering excellent stiffness-to-weight and easy swap capability for builders who want performance and aesthetics. Technically it competes with Chris King on precision but typically targets riders willing to pay for lighter components and faster turnaround; compared to DT Swiss and Hope it is more of a luxury performance upgrade rather than a budget-minded conversion.

Wheels Manufacturing Pro Bearing Press Kit
The Wheels Manufacturing Pro Bearing Press Kit is a comprehensive, pro‑level kit that balances adapter variety and cost, making it a market favorite for teams that service many different Boost hub standards. Technically it competes strongly with Park Tool by offering a wider range of drift sizes and extraction tools in one package, often delivering better per‑adapter value than the HHP-2 while providing more modularity than Park’s single‑purpose press. For mechanics who want a one‑stop solution for both installation and removal across multiple Boost hub types, this kit is hard to beat on utility-to-cost ratio.
