Race Face Oval Cinch Boost Direct Mount Traction Chainring

Absolute Black is one of the leaders in the oval ring market because it leaves no stone—or crank, in this case—unturned. The Race Face Oval Cinch Boost Direct Mount Traction Chainring's very specialized application proves this assertion: its offset and direct-mount design work with a Cinch crank mounted on a Boost frame. This makes installation comically easy and lets you get straight to the chainring's raison d'être, which is reducing the dead spot in your pedal stroke to reanimate lost watts.

By reducing that dead spot, Oval Traction Chainrings boost traction by essentially spreading the power input load more evenly across the pedal stroke. Keeping power constant lets your tire exert a steady force on the trail, so there are fewer instances of slipping out in wet or mucky conditions. The ring shape also spreads the work your body is doing more evenly across the different muscle groups involved, which means less strain on your biological machine, too.

Works well - no complaints

I've used it several times
Size Bought:

Bought for my 2017 5010. Super easy to install. Wanted a smaller front chainring for some of the climbs considering I?m in my 50s now. Definitely noticed a difference on the first few rides but pedaling seems exactly the same to me. Definitely recommend it.

This chain ring is a 6mm offset and my boost frame required a 3mm offset. Had to return. Have received the 3mm offset and love the Absolute Black Oval.

Smoother torque during climbing

I've used it once or twice and have initial impressions
Size Bought:
30t black

Worthwhile upgrade. Nothing odd about the new pedal stroke; the only change is that torque to the wheels during climbing feels more even and natural. On my first ride with the oval, I climbed for 2.5 miles on a rough, rutted trail at 13% average grade. I would have normally stood for several sections but was able to stay seated essentially the entire time. Thumbs up. Just make sure you know whether you need a 3mm (boost) or 6mm offset. I forgot to check and ordered the wrong one at first.
