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

Great ring
I switched to a 1x10 and this front ring is amazing! Installed in minutes clean looking. The narrow wide teeth have held the chain without a guide. I have been abusing this ring and have never dropped a chain.

I went with a 30 tooth because there are long climbs where I ride and needed the lower gearing.

By switching to the single front ring I have shaved over one pound off the bike ! So happy with the choice

When it gets REALLY steep
Bought this 30t ring to augment the gear options on my 1x10 Salsa El Mariachi. I also have the 42t OneUp expander cog. My primary setup is with a 32t chainring, but on rides I know have some leg crushing climbs I wanted a little extra. This 30t ring is perfect. Its easy to swap out and I like that it is threaded and sets up chainline perfectly with the built-in spacing. I have had zero issues with chain drops. This is worth ever penny.

Chain is stuck like glue (in a good way)
Bolted right on to my formally 3X Sram using the spacers supplied. Added this to a new X9 type 2 and the OneUp 42T cassette adaptor for a 1X10 conversion from a 3X10. The old setup lead to chain suck every 2-3 rides so it was time for an upgrade. The 32 definitely lacks on the top end descents and leaves you wanting a bit more but the compromise on the down is worth the up for us non-machines. Overall, very pleased.

switched to 1X
This chainring allowed me to use a 30 tooth ring on my existing spyder crank without replacing the whole crank assembly. It has worked really really well. I have had it for months and have never dropped a chain. It made my bike so quiet.

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.
