FAQs

What tools are needed for installation?

You'll need a chainring bolt wrench or a set of Allen keys for tightening the bolts to the correct torque specification.

Is this chainring compatible with my 94 BCD spider?

No, this chainring is specifically designed for 104 BCD spiders.

What is the recommended torque for the chainring bolts?

Refer to the chainring bolt manufacturer's specifications for the correct torque.

Can I use this chainring with a standard derailleur?

For optimal performance, use a 'CLUTCH' style derailleur (e.g., Shimano Shadow or SRAM Type 2).

How do I know which size chainring to choose?

The size depends on your riding style and the terrain. 32T, 34T, and 36T options are available. Refer to the table.

How do I clean the chainring?

Use a degreaser and a brush to remove dirt and grime. Rinse thoroughly and dry before reassembling.

How long does a chainring last?

The lifespan depends on riding conditions and maintenance. Regularly inspect the chainring for wear. Replace when teeth are worn or damaged.

What type of chain is recommended?

Compatible with Shimano, SRAM, and KMC 10, 11, and 12-speed chains. Make sure your chain is compatible with your cassette.

Troubleshooting

Chain drops frequently.

Ensure the chain and derailleur are properly adjusted. Check for chain wear and replace if necessary. Consider using an upper chain guide.

Chain rubs against the ring.

Verify the chainline is correct and that the chainring is properly aligned. Adjust the front derailleur (if applicable) and check for any bent chainring teeth.

Difficulty shifting.

Inspect and adjust the rear derailleur. Ensure the chain is compatible with the number of speeds on your cassette.
