PASS QUEST NARROW WIDE CHAINRING

  • The ROTOR direct-mount chainring is CNC-milled from a single piece of aluminum, with a hollowed-out chamfered backside to minimize weight while ensuring strength. The teeth remain elongated, with some edges chamfered to prevent the chain from jumping off the tooth tips and preventing chain drop.
  • Our tooth height achieved 8.5 mm, Increased tooth height improves chain retention 
  • We utilize American-standard 7075-T651 aerospace-grade aluminum alloy; the use of superior materials serves as the fundamental guarantee of our product's quality. Additionally, the surface undergoes an anodizing process, which significantly prevents the aluminum from oxidizing.
  • The chamfering design can reduce the weight of the gear plate and make the gear plate more beautiful
  • This product features a 3mm offset; additionally, we offer a hollowed-out version with a 6mm offset, as well as a closed-style option.
  • If you are looking to change your chainring offset and wish to determine the maximum tooth count your frame can accommodate, please contact our customer service team. We can guide you through the measurement and calculation process to determine the maximum tooth count supported by your frame.
  • During installation, you will notice two small dots on the back; these indicate the crank side. Rotate the chainring to the correct position for mounting.
  • To install this product, you will need a removal tool specifically designed for ROTOR direct-mount cranks.

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.
