* 40T Oval 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.
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 110/4 Oval chainring:
First you need to remove crank from the bike. Once removed, unscrew 4 bolts that hold two rings together with T-30 torx key. Take off both original rings. Position Absoluteblack oval chainring in place where the small chainring was (inside position). Please note that small indicator on the chainring Must sit behind crank arm - same way as original chainring indicates its position. You will need new SHORT bolts to mount your new ring (available on our website or you can look for "single" bolts in local bike shop). Close back those four bolts with force of about 5-7Nm. Mount your crank back to the bike. Done
Always use a new chain with a new chainring.

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 causing knee pain and lumpy pedaling cadence. Exactly opposite to how it should be.
