Oneup Components 104 BCD Chainring

OneUp Narrow Wide Chainring

Narrow-wide chainrings are a game changer for single-ring drivetrains. Featuring built-in chain retention technology, the OneUp Narrow Wide Chainring allows you to run a 1x drivetrain without using a chainguide! The trick is the tooth profile consisting of alternating fat/skinny teeth to fit more closely into the narrow and wide plate spacing of a normal chain, "grabbing" the chain and holding it more securely.

Features

  • Narrow Wide tooth profile eliminates chain drop with the perfect chain mesh fit
  • Perfect chainline with 2mm Shims*. For a quieter drivetrain with improved chain wear and best drop performance.
  • Reuse your existing ring hardware. No new bolt packs required, saves you $15.
  • Aggressive crud chamfers for awesome mud shedding performance and extended ring life.
  • Reinforced Wide tooth design provides maximum ring durability when run without a bash.
  • Made from hard wearing 7075-T6 aluminum plate.
  • 30T rings has integrated chainring bolt,to allow the smallest ring size possible on a 104 BCD crank.

*Shims (included with 32, 34 and 36 Tooth Rings) - For 2x crank conversions, shims between the crank and ring get you back to an ideal 49-50mm chainline. For 3x crank conversions, shims under the bolt heads allow reuse of your 3x hardware - No new bolt packs required!

Specifications

  • Material: 7075-T6
  • Weight: 40g (30T), 44g (32T), 54g (34T), 2g (4x shims)
  • Compatible with: 9, 10, 11 Speed Chains and 104 BCD cranks

Comments about OneUp Components Oneup 104 BCD Narrow Wide Chainring:

Converted my m785 to 1x11, this chainring works as expected. My drivetrain includes a sunrace 11-46 cassette, m8000 shifter and derailleur, and sram chain.

Great chainring for converting to a 1x

Comments about OneUp Components Oneup 104 BCD Narrow Wide Chainring:

I used this chainring to convert my 2x to 1x on my '15 giant reign 2. The process was super easy and has never dropped the chain. I have the 32t and the 36t, I use the 36t for riding the snow summit bike park. I have never dropped a chain with this ring and I DO NOT run a chain guide. My buddy bought the race face nw and ended up having to purchase a chain guide because he continued to drop his chain. I have not had that problem. You can't go wrong with this chainring.

  • Q:

    Will this chainring fit a Raceface Evolve XC crankset from 2007? If so, will I need new bolts or spacers? I would prefer getting new bolts over spacers. I want to convert my 3x9 to a 1x9 or 1x10. I have a 9 now.
