What size should I choose
Most CX riders choose 38T as most versatile option.
38T Oval ring will suit best someone who uses 37 or 38T chainring currently. While pedaling, you will feel similar effort to the one riding round 37T ring, but you will gain the speed similar to riding 40T chainring.
36T Oval chainring has the ovality of 34/38T and is best for someone who uses currently 36T round ring (also good for MTB)
38T Oval ring will suit best someone who uses 37 or 38T chainring currently. While pedaling, you will feel similar effort to the one riding round 37T ring, but you will gain the speed similar to riding 40T chainring.
40TOval chainring has an ovality of 38/42T and is best for someone who uses currently 39 or 40T round ring.
42T Oval chainring has an ovality of 40/44T and is best for someone who uses currently 41 or 42T round ring.
44T Oval chainring has an ovality of 42/46T and is best for someone who uses currently 43 or 44T round ring.
46T Oval chainring has an ovality of 44/48T and is best for someone who uses currently 45 or 46T round ring.

Why our oval chainrings work
Our premium 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.
How to mount Direct Mount Chainring
Take the crank off the bike. Unscrew these 3 torx t-25 bolts from the crank arm. 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.
