Product Information

Full details

The SunRace MS Narrow Wide Chainring is an ideal drivetrain upgrade for mountain bikers, gravel riders, and E-bike users seeking improved chain security and long-term durability. Its precise 36-tooth configuration and narrow-wide tooth profile significantly reduce the risk of chain drops on rough, technical terrain, making it a reliable workhorse for varied cycling disciplines. While it provides excellent performance, riders must ensure their crankset is specifically compatible with the 96mm BCD standard before installation.

Extended Product Information

FAQs

Is this chainring compatible with all chains?

It is designed for standard 1x drivetrains. Ensure your chain is compatible with the number of speeds in your rear cassette.

Does this require a chain guide?

The narrow-wide profile is designed to act as a chain retention system, typically making a chain guide unnecessary for most applications.

Can I use this on an E-bike?

Yes, the steel construction is specifically rated for the increased torque loads found on E-bike drivetrains.

Is the BCD measured from bolt hole to bolt hole?

No, BCD is measured from the center of the crank spindle to the center of one of the bolt holes, then multiplied by two.

Does this ring come with mounting bolts?

No, you should reuse your existing compatible chainring bolts or purchase new ones matching your specific crankset.

Troubleshooting

Chain is dropping during shifts

Check your rear derailleur clutch tension and ensure the chainring bolts are properly tightened to the correct torque.

Increased drivetrain noise

Ensure your chain is compatible with a 1x setup and apply a fresh coat of high-quality lubricant to the teeth.

Difficulty fitting onto crank arms

Confirm that your crankset is exactly 96mm BCD; this ring will not fit 104mm or other proprietary BCD standards.

Pros and Cons

Pros

  • Superior chain retention with narrow-wide technology
  • Extremely durable steel construction for long service life
  • Broad compatibility across E-bike, MTB, and Gravel platforms
  • Sleek, low-profile black finish

Cons

  • Steel is heavier than aluminum alternatives
  • Strictly limited to 96mm BCD crank interfaces
  • Requires proper chain length adjustment during installation

Setup, Compatibility & Care

Before installation, verify that your crankset utilizes the 96mm BCD pattern. When installing, ensure the chainring is correctly oriented so the wide teeth align with the outer links of your chain. Use a torque wrench to tighten chainring bolts to the manufacturer's recommended specifications for your specific crank arms. Regular maintenance involves cleaning the teeth with a degreaser after muddy rides and applying a high-quality chain lubricant to reduce friction between the chain and ring.
