Overview
 
Our premium 1X Sram 94BCD Oval traction chainrings are designed for Sram X01, X1, GX, NX and GX Eagle cranks. They feature exactly same oval shape as our other oval chainrings. 
 
Advantages of our special 94bcd chainrings:
  • We mastered our oval chainrings to perfection, so you can get best possible advantage from the oval/elliptical shape. 
  • 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! 
  • Special 3D teeth machining for ultimate mud relief decrease wear and noise dramatically
  • All rings have built in threads for easy of mounting and reduction in weight
  • 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 
  • Greatly improves traction and climbing abilities

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

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 94bcd Absoluteblack oval chainring:
There is a small mark (triangle shaped) on the inner circumference of the chainring.

This mark Must sit behind the crank arm. Please note that original Sram bolts are too short to mount this chainring. You will require longer bolts that can be purchased from us. Pick "Long set of 4" (or use any "double bolts" from another crank)
How to mount 94bcd Absoluteblack oval chainring:
 

Chain options:
10 or 11spd chain for geared bike or 6-8 spd one for SS (1/8" also fits). 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.
 
​Don't know what bolts to use with this oval chainring with integrated threads? 
They are a standard bolts. You can use a granny ring bolts (from 64bcd chainring) or use the ones that connect middle and big ring from 3X crank. You can also buy them from us in Bolts tab. Pick "Long" ones.
 
FAQ
 
​What size should I choose?

30T: 134mm ; 32T: 143mm ; 34T: 151mm ;
