Shimano Oval Traction Chainring
Designed to pair with your Shimano XT or XTR crankset, the Shimano Oval Traction Chainring brings claims of improved rear wheel traction resulting from a more consistent pedal stroke. Absolute Black claims that this oval profile maximizes power transfer and smooths the rotation by reducing dead spots and capitalizing on the sweet spots compared to standard round rings. Each chainring size features its own unique oval profile, but the mud-clearing and chain-retaining narrow-wide tooth profile is universal across sizes.

Varying Quality / Experiences
I put a pair of these on my road bike and absolutely love them. I loved them so much that I spent hundreds of dollars to put one on my commuter. Worst decision ever. I throw my chain ALL THE TIME. It varies. Sometimes I'll go a whole week without throwing the chain. Today, on my 2.5 mile commute, I threw the chain three times, which is what spurred me to write this review. I've had the bike professionally tuned and adjusted twice. It doesn't help. If anything, it makes it worse. AB's customer service on the issue wasn't helpful either. They acknowledged that their rings aren't designed to keep the chain on "but we're working on it" they said. In the meantime, they suggested taking a link out of the chain to increase the tension. If anything, that only made it worse. I might recommend these for a road bike with a tight derailleur, but not on anything else. It's a shame. I do love them on my road bike, and conceptually, they SHOULD be awesome on a MTB or cross bike where they would improve traction. Hopefully you'll have better luck than I did.

Up and over everything!
- I've used it once or twice and have initial impressions
I just got this ring and it does make a difference on those techie climbs and areas where you need to throw the hammer down to make it over an obstacle. I haven't noticed the ring's oval profile while I'm pedaling at a steady cadence and it definitely doesn't affect my knees like those previous generations of oval chainrings. The jury is still out on the longevity of this product but the machining quality is self evident when you see this ring in person. My initial impression of this ring is a definite grade A!

It feels as though I have picked up a lower gear for climbing with no sacrifice in the higher gears.

Will this fit Shimano SLX? I think it's M7000?
