           PASS QUEST NARROW WIDE CHAINRING

  • 110-5BCD positive and negative chainrings are CNC milledfrom an entire aluminum plate, and the back is hollowed outand chamfered to ensure strength while also reducing theweight of the chainrings. The chainring adopts an elongatedtooth shape, which makes it difficult for the chain to escapefrom the teeth even if it jumps violently, thus ensuring that thechain does not fall off.
  • (BCD:THE CENTER HOLE OF THE DISC NAILFORMS THE DIAMETER OF THE CIRCLE)
  • Our tooth height is 8.5mmThe teeth extend far beyond the chainWhen you jump like crazy.The chain jerked too hard to get out of the teethSo as to truly achieve the chain
  • 7075 aluminum alloy is difficult to anode
    For this reason,we through many product proofingUpgrade sandblasting anode to matte anodeMore beautiful texture
  • For lightweight and rigid gearWe use a lot of hollowed out designsIn order to make the gear plate moreBeautiful and full of three-dimensional senseThe edges and corners of the disc are chamfered
  • In order to reduce weight and increase rigidity, we have adopted a lot of hollow designs. In order to make the gear plate more beautiful and three-dimensional, the edges and corners of the plate are chamfered.
  • Maximizes contact area between the screw and tooth plate; simplifies installation; effectively reduces abnormal noise
  • Narrow wide tooth, it design for 1x speed only, can not use as 2x speed, not support front shifting derailleur.
  • Locking torque: 6-8 N·M

    Excessive torque may damage the screw.

110BCD (5-bolt Hollow) Round Road Bike Narrow Wide Chainring

J
Jaylan Raynor

Lightweight. Well machined: clean finish with no burrs. Comes with short bolts required for a 1x setup. This is the bee's knees. I am running this in a 1x12 configuration on a 410mm chainline. Even with 0 offset, there is only crosschaing in the 2 lowest gears (max 32T) Have not experienced a single chain drop

How to calculate gear inches for an oval chainrings

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.

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.
