Authentic Ravin R190 Crossbow String and Cable Set for R9-R29X Series

Authentic Ravin R190 Crossbow String and Cable Set for R9-R29X Series

Maintenance Interval and Importance

To maintain maximum downrange accuracy and safety, Ravin recommends that strings and cables be replaced every 2 years or 400 shots, whichever comes first. High-velocity crossbows subject the archery string to immense friction and tension. Over time, fibres can stretch or wear internally, leading to cam lean or a loss of bolt speed. Regular replacement ensures that your timing remains perfectly synchronised for every shot.

Technical Specifications (R190)

Preparation and Installation

Replacing strings and cables on a Ravin is a specialised task. Use only the Ravin Multi-Press to perform this service. Using a standard bow press can lead to catastrophic failure of the limbs or cams due to the unique geometry of the HeliCoil design. Before installation, inspect the set for any shipping damage. Once installed, it is vital to check the cam timing marks to ensure both limbs are loading identically for consistent bolt flight.

The HeliCoil Advantage

The R190 cable system is the backbone of the HeliCoil engine. It allows the cams to rotate 340 degrees while staying perfectly level. This level-cam travel is what gives Ravin its legendary accuracy. Because the cables take on such a massive load during this rotation, they are built with zero-stretch materials to maintain their integrity shot after shot.

Care Instructions and Safety Warnings

• Waxing: Apply high-quality string wax to the exposed strands regularly to prevent fraying and moisture absorption.
• Avoid Dry Firing: Never fire the crossbow without a bolt. A dry fire will likely snap the string and cables instantly and may damage the limbs.
• Inspection: Check the servings for wear, especially around the cam loops and where the string interacts with the anti-dry fire mechanism.
• Proper Storage: Store your crossbow in a cool, dry place. Excessive heat can degrade the synthetic fibres and the wax coating.

Recommended Accessories

To prolong the life of your new R190 set, we highly recommend using Ravin String Fluid and Ravin Rail Lube. For those performing their own maintenance, the Ravin Multi-Press is an essential requirement. Always use Genuine Ravin Bolts to ensure the nock fit is perfect, protecting your centre serving from premature wear.
