PASS QUEST NARROW WIDE CHAINRING

  • Milled from a single sheet of aluminum with precision CNC machining for an ideal balance of stiffness and lightness.The back is hollowed and chamfered to reduce weight while retaining structural strength.
    An extended narrow-wide tooth profile projects beyond the chain’s contact surface, making chain drops highly unlikely even under aggressive chain movements. Compatible with various 120BCD crank shapes for effortless fitment.
  • Our tooth height achieved 8.5 mm, Increased tooth height improves chain retention 
  • 7075 aluminum alloy is difficult to anode
    For this reason,we through many product proofing
    Upgrade sandblasting anode to matte anode
    More beautiful textur
  • Silky Power
    8.5mm Extended Teeth
    -Deeper tooth engagement for superior chain retention.
    Fewer Chain Drops
    -chain is farless likely to pop off underrough riding
    or high-torque shifts.
    Solid Pedal Feel
    -More secure engagement yields a firmer
    more responsive pedal stroke.
    Stronger Sprints
    -Direct powertransfer for decisive acceleration.

  • Includes 4 steel mounting bolts. Higher shear strength
    And torque capacity for a more secure installation.
  • The chainring is CNC-machined from high-strength
    7075-T651 aluminum,combining strength and toughness
    To withstand impacts and collisions.
    Its excellent wear resistance ensures durability against
    long-term use and chain friction.
  • (BCD:THE CENTER HOLE OF THE DISC NAILFORMS THE DIAMETER OF THE CIRCLE)
  • Narrow wide tooth, it design for 1x speed only, can not use as 2x speed, not support front shifting derailleur.
  • When using a 12-speed chain, please replace the original SHIMANO fast sprocket with a KMC 12-speed fast sprocket.

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.
