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 Gray 4.0mm size fits 13 gauge nipples from DT Swiss, Sapim, and others. This is a uniquely shaped bit that offers safe repeatable use where industry standards have not been firmly established.
