PASS QUEST 2X CHAINRING

  • The ROTOR 110BCD 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
  • Variable Speed: The chainring is matched with flywheels with different numbers of teeth. It can provide more speed options than the single chainring system. It allows riders to find the right gear ratio under various road conditions. It allows riders to ride effciently under different road conditions.
  • Specially Shaped Pins:
    Designed to ensure precise chain engagement, these pins facilitate a tighter and more secure fit between the chain and the chainring.
    This significantly enhances both riding control and safety.
  • The double chainrings are designed well. Do not mix different brands and different gear numbers. Smooth speed change cannot be guaranteed.
  • All PASS QUEST double chainring must be used as pass quest original pair set. Mix with other brand chainring will not work.
  • Precision Component Notice Chainring bolts are high-precision parts.Improperinstallation may cause damage.
    Not covered under warranty.
  • We provide standard screws free of charge.
    Locking torque: 6-8 N·M
    Excessive torque may damage the screw

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.
