• Chain breaker (if replacing chain)
• Torque wrench (recommended for precise installation)
• Degreaser and clean rags

Kurulum Adımları:

1. Hazırlık: Ensure your bicycle is securely mounted in a repair stand. Shift the chain to the smallest cog and chainring.
2. Remove Existing Pulley Cage: Carefully remove the existing derailleur pulley cage. This typically involves unscrewing the pivot bolt that holds the cage to the derailleur body. Note the orientation of the original cage and pulleys.

The ceramic bearings further minimize resistance, contributing to a smoother and faster ride.

• Sürtünmenin Azaltılması: The larger diameter pulleys and ceramic bearings significantly reduce frictional losses in the drivetrain.
• Improved Shift Accuracy: The precise design and long tooth profile on the lower pulley contribute to consistent and accurate gear changes.
• Çok Yönlü Kullanım: Suitable for both on-road and off-road cycling conditions.
• Uyumluluk: Fits both SS (short) cage and GS (mid) cage Shimano RX800 and GRX derailleurs.

Bakım

Regular maintenance will ensure the longevity and continued high performance of your Kogel Kolossos Oversized Pulley Cage.

Temizlik:

• Bol su ile durulayın ve tamamen kurulayın.
• Avoid high-pressure washing directly on the bearings.

Yağlama:

• While the ceramic bearings are designed for low maintenance, occasional light lubrication of the chain and the interface between the pulleys and the cage can be beneficial.
• Use a high-quality, low-viscosity chain lubricant.

Denetleme:

• Periodically inspect the pulleys for wear, especially the teeth. Worn teeth can lead to poor shifting and chain skipping.
• Check the cage for any signs of damage, bending, or cracks.
• Tüm cıvataların iyice sıkıldığından emin olun.
