Shibata GRK Lightweight Aluminum Knuckle Ver.HRP (Blue)

Shibata GRK Lightweight Aluminum Knuckle Ver.HRP (R31S347BL). The next step on from the Ver.Y knuckle, developed under HAYATO with refined geometry for a sharp, responsive steering feel and better front-end tracing.

Notes: When upgrading from Ver.Y or V1 knuckles with Shibata axles (R31S024 / R31S064 / R31S131), clearance adjustment is needed, e.g. a 1mm idler spacer (R31S123). Use 1050 bearings, 4mm thick.
