Absolute Black Cinch Boost Oval Ring

Absolute Black Cinch Boost Oval Ring

The Absolute Black Cinch Boost Oval Ring is ready to rip it up with its beautifully machined, lightweight and stiff construction. Simply put, this is the best looking spiderless ring we've ever seen. Its special direct mount interface is compatible with Race Face Cinch cranks. The spiderless setup is super clean and saves a great deal of weight over a normal spidered setup. Oval rings spin smoother and promote optimal power transfer, eliminating dead spots in the pedal stroke. The Cinch Boost Oval ring has Absolute Black's specialized narrow-wide tooth profile which retains the chain snugly, preventing dreaded chain droppage. Perfect for single ring or singlespeed use.

Features

  • Oval rings help the rider spin smoother and generate more power
  • Replaces the existing chainring and spider on 3-bolt GXP cranks
  • Narrow wide tooth profile keeps the chain snug, allowing you to leave the chainguide behind
  • Fits Race Face Cinch Cranks
  • Works with 1x9/10/11sp or single speed setups
  • Designed in UK, manufactured in Poland

It just Works
I have only used this ring on a few rides so far but notice that I have more traction while climbing the really steep, slick terrain. It seems to control the rear tire speed and torque so you don't spin the tire until you feet are at 12 and 6 and you don't have the power to keep moving. I was able to climb 3 hills that I always had to walk part way. as far as fatigue I did not notice much change. Maybe on a longer ride I will fell that.

Helpful for those grinding seated climbs.
The help from the oval chain ring is not overwhelming noticeable.
If I am just grinding away on a climb and doing it slowly this is when it helped me. I did notice I was climbing certain hills without the usual exhaustion or fatigue in my legs. As long as you are climbing at a slow tempo you may notice the difference other than that it felt like a normal round chain ring to me.

How is this different than the non-Boost version?
JAMES L on May 3, 2017
BEST ANSWER: Boost drivelines are 3mm wider than standard, so this chainring is offset 3mm to match.
Is this for raceface CINCH or is this for SRAM GXP? Title says cinch, description says GXP (these are 2 very different interfaces...)
