Oneup Components XTR M9000 Oval Ring

Oneup XTR M9000/M9020 Oval 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 fits Shimano XTR M9000/M9020 11 speed cranks and 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

Biopace or worth the $$$ ....?
The oval ring - subtle. With the two tooth gain and loss I would recommend downsizing two teeth from what you would normally ride. Totally my opinion, but it's worth the couple extra bucks. Good durability, and not a single dropped chain so far. The included bolts are a huge plus too, mounting to the M9000 crank is a piece of cake.

Does this come with bolts for mounting or is it expected to be mounted with the bolts that come with the crank sans tabs?
