PASS QUEST 2X CHAINRINGThe F107BCD variable speed double disc is CNC milled from the whole aluminum plate, and the back is hollowed out and milled and chamfered to ensure the strength and reduce the weight of the chainring! The speed change disc is designed as a whole, and other gears cannot be replaced, and different brands cannot be matched at will. It takes time to polish the aluminum plate with a thickness of 5mm. The texture and triangular structure ensure the hardness of the chainring while bringing a lighter experience |

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.
