  • Hard anodized coating
  • Unique 1/8" quiet drive technology

Why choose this product

Engineered for BMX Performance

This Black Ops Micro Drive chainring is built for the demands of BMX riding. Its CNC-machined 6061-T6 alloy construction offers a perfect balance of strength and lightness, crucial for agility and impact resistance. The hard-anodized coating provides long-lasting durability against wear and tear. Unlike generic chainrings, its unique 1/8" quiet drive technology ensures a smoother, quieter ride, allowing riders to focus on their performance. Imported directly from authorized US retailers, it guarantees authentic quality and superior craftsmanship for your bike.

Who It's For vs. Who Should Skip

Ideal for BMX riders seeking a high-quality, durable, and quiet single-speed chainring upgrade for their 3-piece cranksets. Perfect for those who value precise engineering and a sleek black aesthetic. Skip if you require a chainring for geared drivetrains or if your crankset uses a non-standard mounting system. For riders needing extreme torque resistance on e-bikes, consider steel or reinforced composite chainrings.

How to use

  • Verify Crankset Compatibility — Ensure your BMX bike uses a standard 3-piece crankset. Confirm your existing chainring's BCD or mounting type matches the specifications for this Black Ops Micro Drive chainring, which is designed for 1/8" chains.
  • Remove Old Chainring — Using appropriate tools (e.g., crank puller, chainring bolts tool), carefully remove the old chainring from your crank spider. Clean the crank spider and surrounding area to prepare for the new installation.
  • Install New Chainring — Align the Black Ops Micro Drive chainring with the crank spider's mounting points. Secure it using new chainring bolts and nuts, tightening them evenly in a star pattern to ensure proper seating and prevent stress on the components.
  • Install Chain and Adjust — Install a new 1/8" chain, ensuring it runs smoothly over the 25t chainring. Adjust chain tension as needed for optimal performance and to minimize slack, which is crucial for single-speed setups to prevent chain drops.

FAQ, See What Others Asked

How do I determine the correct BCD for a replacement chainring?
Measure the distance between adjacent bolt holes in millimeters. For 4-bolt asymmetric or symmetric spiders, calculate or measure the diagonal distance between center-to-center opposite bolt holes to match standard BCD dimensions like 104mm or 110mm. This Black Ops chainring is designed for 3-piece BMX cranks, which typically use specific BCD standards or direct-mount systems.
What is the benefit of a narrow-wide chainring on a 1x drivetrain?
Narrow-wide chainrings feature alternating tooth thicknesses that snugly fit the alternating inner and outer link plates of the bike chain, eliminating the need for a front derailleur or chain guide while preventing chain drops over rough terrain. This Black Ops chainring is specifically for 1/8" chains on single-speed BMX setups.
Is this Black Ops Micro Drive chainring suitable for Indian riding conditions?
Yes, the Black Ops Micro Drive BMX Chain Ring is built for durability with its CNC-machined alloy and hard-anodized coating, making it resilient to dust and general wear. While not specifically tested for extreme Indian monsoon conditions, its robust construction offers good resistance. All customs duties and GST are included in the price, and it ships via ExpressBox tracked delivery.
How do I buy an original Black Ops Micro Drive BMX Chain Ring in India?
Purchase the original Black Ops Micro Drive BMX Chain Ring from crowcrowcrow.com. We import directly from authorized US retailers and brand partners, ensuring factory-sealed products. All customs duties and GST are pre-paid and included in the listed INR price. Your order is shipped via ExpressBox with tracking for secure delivery across India.
What is the difference between this chainring and local alternatives?
This Black Ops chainring is CNC machined from 6061-T6 alloy with a hard-anodized coating and unique 1/8" quiet drive technology, offering superior durability and a quieter ride. Local alternatives may use less robust materials or lack specialized features like quiet drive technology, potentially leading to faster wear or more noise.
Does this chainring fit my BMX bike?
The Black Ops Micro Drive BMX Chain Ring is designed to fit standard 3-piece BMX cranksets. It uses 1/8" chain width and has a 25-tooth count. Verify your crankset type and desired gearing before purchasing to ensure compatibility with your specific BMX bike setup.
