Park Tool 內置銅頭鋼絲扳手 - 6mm六角 (SW-19)

The 6mm hex fits perfectly into those recessed rim holes, making spoke adjustments on my deep-section wheels much less fiddly. It’s a solid, well-machined tool that turns a frustrating job into something I can actually finish in one session.

I’ve been using this wrench to true up my deep-section rims, and the 6mm hex head fits perfectly through the tight access holes. It feels sturdy and well-machined, no slipping at all.
