PASS QUEST SPIDERThe disc claw features a round, star-shaped design, offering you a choice of two shapes. The special design of the plate jaw makes the transition between the plate jaw and the tooth plate smooth and supports the double plates. We used a lot of hollow out design to make the plate claw more beautiful and full three-dimensional sense of the plate claw edges and corners have done chamfering treatment |

Which size of an oval should I choose
We always recommend swapping like for like, so if you have a 32T round ring at the moment, you should consider getting a 32T oval. The same applies to our shiftable road ovals, we recommend that you purchase ovals with the same teeth count as your round rings.
How to calculate gear inches for an oval chainring
Exactly same way as for round chainring. You just need to use the nominal size in the calculation of an oval ring you have. That is, if you buy 32T oval you use for calculation 32T size. Reason for this is 32T oval chainring has same circumference as the 32T round. We optimize the shape but not circumference - it stays constant. Distance between each teeth always has to remain at 12.7mm to engage the chain properly. You can use any online calculator to get gear inches for an oval chainring.
