Oneup 104 BCD Oval 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.

This model of the OneUp is compatible with 9, 10, 11 Speed Chains and 104 BCD cranks. It also features a 12% ovality with a 115 degree clocking from the crank arm to put the major axis of the oval in your power stroke. This efficiently utilizes the strongest muscle groups to increase positive work, while picking up the slack in the weaker zones to reduce the negative work, smoothening out the rotation to a perfect spin.

Threaded for included M9 hardware. No M7 M9000/M9020 bolt pack required

worth a try
I was use to running a 32t sprocket, with this it immediately felt like I was running a bigger gear, however it was easier to spin the cranks. a strange sensation. I have noticed on technical assents it keeps the rear tire traction more constant. I was under the impression that it was snake oil, but I guess I was proven wrong, just put a 40t dinner plate on the cassette I'm anxious to see how it does with it. basically the best way to sum it up is I don't not like it.

Great upgrade
I notice that the climbs are a bit easier and virtually no overall noticeable difference in the gearing. If you are thinking about dropping down to a 30T, a 32T oval is a great option.

No reason to go round
This is installed on an Ellsworth Truth that gets ridden in more aggressive terrain than the usual cross counrtry trails. Upgraded to a 1x11 Shimano system. Thought I'd give this a try since I was going to buy a 32 tooth chain ring anyway. The only fiddly bit with the install was adjusting the One up chain upper only guide to fit the varying diameter of the oval. The guide is very close at the large diameter but I've had no issues in the sloppy mud. With regard to pedaling; I noticed the oval for about 30 seconds. Now I can't feel it. And it seems that climbing steep rooted/edgy sections is much smoother with fewer spinouts. This is subjective but it's on the same bike/same trails. Have not dropped a a chain yet. But that may have a lot to do with the chainguide.

Can you use this w a 9 speed 2x9? 22/32 w bash guard? Thanks
Hayop30 on Dec 11, 2016
BEST ANSWER: No, this is a wide/narrow chainring. That means every other tooth is wide, to fit in the wider link of the chain, and ever other tooth is standard/narrow to fit in the narrow links of your chain.

Because of this the chain only fits onto it when the proper links are lined up with the proper teeth. It's meant to hold the chain in place and keep if from jumping off, it's not meant too be shifted.
