PASS QUEST NARROW WIDE CHAINRING

  • As the number of teeth increases—particularly when utilizing larger chainrings—the chainline tends to shift outward, away from the bike frame. This can lead to issues such as chain skipping or dropping during riding. We have designed this chainring with a 3mm offset and a Narrow-Wide tooth profile to correct and adjust the chainline, thereby bringing it back into alignment with the bike's centerline.
  • Exceptional Rigidity:
    The chainring is precision-machined via CNC from high-strength 7075-T651 aluminum alloy. Its triangular and textured structural design ensures outstanding rigidity, delivering direct and efficient power transfer.
  • Chamfered Strips: Extensive chamfering ensures the chainring remains lightweight. To optimize both weight reduction and rigidity, we have incorporated an extensive striped design. Furthermore, to enhance the chainring's aesthetic appeal and create a sense of three-dimensional depth, the edges and corners of the plate have been meticulously chamfered.
  • Of course, if your current chainline is already standard, installing a chainring with a 3mm offset will actually have a counterproductive effect: the teeth will sit even closer to the frame, causing the chain to rub against the chainstay. This practice will inevitably lead to wear and tear on your bicycle.
  • Includes custom-made titanium alloy bolts. (Color options are available; simply specify your preference in the order notes.)
  • Narrow wide tooth, it design for 1x speed only, can not use as 2x speed, not support front shifting derailleur.
  • Titanium screw: 12N·M

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.
