Park Tool RP-1 – Precision Straight-Head Plier for Bicycle Inner Rings

The Park Tool RP-1 is a specialized bicycle repair plier designed for installing and removing 0.9 mm inner rings on spoke wheels. Its straight-head design provides precise access in tight wheel spoke configurations, making it an essential tool for wheel truing and spoke maintenance.

• Straight-head jaw fits 0.9 mm inner rings with exact grip, preventing slippage and spoke damage
• Blue and silver two-tone finish offers clear visibility against dark wheel surfaces
• Compact 85 g weight fits in any bike tool bag without adding bulk
• 24-month manufacturer warranty ensures long-term reliability for daily workshop use

What Sets the RP-1 Apart

Unlike standard pliers that can mar delicate spoke nipples, the RP-1's hardened jaw surfaces are engineered specifically for the 0.9 mm inner ring profile. The straight-head geometry reaches spokes that angled tools cannot access cleanly, reducing the need for multiple tools during wheel builds.

Ideal for...

Home bicycle mechanics and professional wheel builders who work with standard 36- or 28-spoke wheels requiring precise inner ring installation. The tool is particularly suited for riders who maintain their own wheels and need a reliable, dedicated plier for spoke nipple work.

Application of Park Tool RP-1

1. Position the straight-head jaw around the 0.9 mm inner ring on the spoke nipple
2. Apply steady, even pressure to seat or remove the ring without twisting the spoke
3. Use the blue/silver finish to quickly identify the tool in a crowded workbench
4. Store in a dry tool case after use to maintain jaw precision over time
