Designed for maximum ergonomics and precision fit, these sit comfortably in your hand and have a non-marring slip fit over spoke nipples.

The SI handle design is a large-format high-leverage block that is easily grasped from multiple angles. Its design focuses on low overall height, for applications where a clamp-style spoke holder is desired. Made from laser-fused Nylon.

The 4.0mm size is useful on nipples for 12ga spokes including DT-Swiss, Pillar, Sapim, and more. Fits 3.9mm, 4.0mm, and 4.1mm with precision! This is a uniquely shaped tool that offers safe repeatable use where industry standards have not been firmly established.
