Overview
 
Our premium 1X Sram Direct mount Oval GXP compatible chainrings are designed for GXP and Long BB30 spindle cranks. Fits Sram XX1, X01 and others. Also replaces 76bcd chainrings to convert to direct mount solution.

Advantages of our special Direct mount chainrings:
  • Finest design to provide excellent weight to strength ratio
  • One of a kind special oval shape (Patent Pending)
  • Unique Patent Pending narrow-wide teeth profiles to keep your chain in place for minimum 12 months!
  • They save weight because they don't need the spider and chainring bolts.
  • The ability of installation of a smaller ring sizes that can't be mounted on regular spider.
  • Superb quality and great look.
  • You will ride faster using ovals. If you keep using round ring then others will get quicker.
  • You will not "feel" the oval shape at all
  • Reduces stress on knees
 

The most advanced, Patent Pending alternate wide and narrow teeth profile currently produced, guarantee minimum 12 months of excellent chain retention capabilities! We mean it. Always use a new chain with a new chainring.

The World's best oval (elliptical) mtb spiderless traction chainring - period!. Non circular chainrings, Non-round chainrings. Asymmetrical chainrings.

Why Oval

Why our oval chainrings work
Our traction Oval chainrings work because a rider does not produce power evenly through a pedal stroke; they maximize the part of the stroke where power is produced and minimize resistance where it isn't. Oval rings make the spin cycle a lot smoother and are easier on legs while climbing. Believe it (or not), but a round chainring doesn't transfer torque to your rear wheel as smoothly as an Oval one. You will actually feel your stroke to be more "round" with an Oval shape than with a round chainring.

Why it matters
Traction, Traction and Traction. With oval rings rear tire traction improves greatly on loose and slippery terrain. Smoother power delivery to your rear wheel means that you will be able to maintain better, constant cadence; get less stress on the joints (knees) and therefore be able to keep certain level of effort for longer. This results in higher average speed. Moreover, 11 studies made by various Universities in the World show that using oval chainrings human legs utilize more muscle groups (compared to round one), but each of them to lesser degree. Load from pedaling an oval chainring is spread over greater muscle mass which in effect gives you the feeling of fresher and more relaxed legs. It is world's finest oval chainring backed by tens of thousands of customers.
Technology
 
Word on BIOPACE
Please understand that this is not Biopace technology. Shimano created Biopace with the completely wrong orientation of the biggest radius of the oval. Instead of positioning it in power zone which is slightly below the level of the crank, they clocked it to the dead zone where human generates least power. The result was that in power zone pedaling was too easy and in dead zone very difficult. Exactly opposite to how it should be.

Round rings do not optimize the way humans produce power

Other elliptical chainrings
Clocking (timing) and shape of the oval are the most crucial parts of the design. Ride quality of Absoluteblack Oval ring will be different to ovals from brand X or Y. 2 years of development of our ovals resulted in commercially most successful product of its kind. AbsoluteBlack is the First company who managed to successfully popularize ovals in mountainbike sport. Please note: Other manufacturers offer one timing and ovality setting for all chainring sizes, but pedaling behavior changes with each size considerably. To optimize for this, every chainring size needs to be a bit different. For example the smaller the chainring size the bigger the ovality has to be to help climb steeper hills more effectively. This is where we specialize in and optimize every size to particular pedaling style. This is also why we do not provide information about timing and exact ovality of the chainring as each one is different.

 

The importance of timing and shape with oval chainrings
The oval chainring movement across all cycling disciplines is growing rapidly, led by absoluteBLACK, the world leaders in this important product category.

However, not all oval chainrings share the same performance characteristics as absoluteBLACK. The 'clocking' (timing) and shape of the oval are the most crucial parts of any oval chainring design, absoluteBLACK spent three years in design development and have perfected both timing and shape design elements - ensuring the ride quality of absoluteBLACK oval ring will be different and superior to ovals from other brands (as many abosluteBLACK customers already realised).

Where most other brands retain the same timing (position of the crank arm relative to the oval) and shape of the oval across all their sizes - because it's cheaper and less time consuming. absoluteBLACK believe that each different size ring requires a bespoke, optimised, perfect pedalling solution. So that is what we do - for every chainring absoluteBLACK make. For example, the smaller the chainring size, the bigger the ovality has to be to help climb steeper hills more effectively. We keep our exact Patent Pending data a secret, to ensure we get the best possible absoluteBLACK advantage over other brands, and you get the best possible ride experience.
Installation
 
How to mount Sram GXP and BB30 Oval chainring:
You need to unscrew these 3 torx t-25 bolts from the crank. Then remove the spider+chainring combo you currently have there. Clean the splines and put some grease on them. Position the chainring in place (note there is only one way to fit this Sram chainring so you don't have to worry how to do it). Close all 3 bolts to about 5-7Nm.
 
It is ideal for 1x 9/10/11 system and Singlespeeds!. Oval (elliptical) chainring does not compromise the work of clutch mechanism in rear derailleur(video at the bottom). It also does not require chain tensioner when using in singlespeed application. Riding out of saddle on the uphill will become more pleasant. These chainrings also help you to recover after knee injuries as pedaling becomes smoother and less exhausting. It is the most advanced oval chainring currently on the market.
 

Chain options

  • 10 or 11spd chain for geared bike or 6-8 spd for SS. If used in 1x9 drivetrain - 10spd chain must be used to obtain the performance. (yes - 10spd chain will work great on 9spd cassette)

Chainguide needed?

  • No. But if you want one then chain guide should have 2 teeth more capacity than nominal oval ring size.
 
FAQ
 
What size should I choose?
  • 26T Oval chainring has the ovality of 24/28T and is best for someone who uses currently 26T round ring. (Fatbikes!)
  • 28T Oval chainring has an ovality of 26/30T and is best for someone who uses currently 27 or 28T round ring.
  • 30T Oval chainring has an ovality of 28/32T and is best for someone who uses currently 29 or 30T round ring.
  • 32T oval ring will suit best someone who uses 31 or 32T chainring currently. While pedaling, you will feel similar effort to the one riding round 31T ring, but you will gain the speed similar to riding 34T chainring.
  • 34T Oval chainring has an ovality of 32/36T and is best for someone who uses currently 33 or 34T round ring.
  • 36T and bigger? Look at CX category for CX1 OVAL SRAM. It is same chainring just bigger sizes we advertise for Cyclocross.

Frame clearance (biggest dimension of the oval tip to tip of tooth):

  • 26T: 118mm
  • 28T: 127mm
  • 30T: 134mm
  • 32T: 143mm
  • 34T: 151mm
