Description

Upgrade or complete your drivetrain with a OneUp Components 4 Bolt Chainring. These chainrings are easy to fit and will suit a range of 4 bolt cranks in a handful of BCD's. Choose from standard round chainrings or try out an Oval ring for better traction. Made from a high-grade 7075-T6 aluminium these chainrings use a Narrow Wide tooth profile that eliminates chain drop with a perfect mesh between the chain and ring. Compatible with 9, 10, 11 and 12 Speed SRAM Chains (not compatible with Shimano 12-Speed Chains).

Features:

Round:

  • 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 aluminium plate
  • Weight: 40g (30T), 44g (32T), 54g (34T)

Oval:

  • Get ultimate traction by smoothing out the torque delivery to your rear tyre. For MTB riding, oval rings provide more constant torque to the rear wheel thereby reducing spinouts and stalls on tough climbs.
  • 12% ovality (32T is equal to a 30T-34T range)
  • 115° clocking from the crank arm puts the major axis in your power stroke
  • Narrow Wide tooth profile eliminates chain drop with the perfect chain mesh fit
  • Perfect chain line with built-in offset. For a quieter drivetrain with improved chain wear and best drop performance
  • Aggressive crud chamfers for awesome mud shedding performance and extended ring life

  • Round Only: 2mm Shims included with 32T and 34T 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

BEAUTIFUL TEETH

I have now used both the one up and wolf narrow wide chainrings on the same bike and trails. ONEUP no derailments WOLF one derailment.
Wolf is 3 grams lighter and looks like it would clear mud better
One up design looks more robust and reallly beds in the chain
Both look great and r exceptionally well engineered

Love it!

Nice quality & easy to install

This is a great ring.
I’m a big boy and any advantage I can get is appreciated.
It’s amazing how much more traction I get on the techy uphill bits. I’m cleaning new lines without putting a foot down.

And maybe the best part is noticing that the day after a big ride, My knees aren’t sore.

in Oval we trust.

Oval narrow-wide might be the best value upgrade you can buy for a 1x bike. I popped this on my XC bike and chain retention has been flawless, with less slap and noise too. Whilst the Oval doesn't transform the bike, it noticeably improves the "feel" driving forward at slow speeds with lower cadence- which is particularly advantageous when climbing, in slow technical sections, when applying small 'kicks' to power over and through gnarly bits, and finding traction on loose ground. Love it.
