An innovative 36mm box spanner with a light-weight aluminum extension to boost leverage while keeping it compact for easy storage on the bike. The extension nests over the wrench for compact storage at 8 1/4” (21cm) in length and can be extended to 12” (30.5cm) for maximum leverage. The extension handle has finger-friendly radiused edges and a non-slip finish providing you with a solid grip. It’s an essential axle wrench for road-side tire repair or chain adjustments on any bike with 36mm axle nut. The narrow profile allows the rear axle nut to be loosened without removing the exhaust for easy belt adjustment on Touring models.
