PASS QUEST NARROW WIDE CHAINRING

• Important Notes:
• 
• FC5800/FC6800(Four claws without arc)
  FC-R7000/FC-R8000 FC-R9100(There's an arc in the upper right corner)
  FC-R7100/FC-R8100 FC-R9200(There are a total of two curved sections: one in the upper-right corner and one in the lower-right corner)
• The R92-81-7100 chainrings are CNC milled from  anentire aluminum plate,and the back is hollowed out and chamfered to ensure strength while also reducing the weight of the chainrings. The chainring adopts an elongated tooth shape,which makes it difficult for the chain to escape from the teeth
   even if it jumps violently, thus ensuring that the chain does not fall off.
• Lengthened tooth design:  Our tooth height is 8.5mm.The teeth extend far beyond the chain.Whenyou jumplike crazy.The chain jerked too hard to get out of thet eeth.So as to truly achieve the chain.
• Anodized Surface:  7075 aluminum alloy is difficult to anode.For this reason,we through many product proofing.Upgrade sandblasting anode to matte anode.Upgrade sandblasting anode to matte anode.More beautiful texture.
• Countersunk Structure:  Maximize the contant area between the screw and the gear plate. Simpler installation effect. Effectively reduce abnormal noise.
• Chainring Strength:  The chainring is CNC-made from high-strength7075-T651 aluminum.Triangular and textured structure ensures chainring rigidity.Use force directly.
• Narrow wide tooth, it design for 1x speed only, can not use as 2x speed, not support front shifting derailleur.
  

• We provide standard screws free of charge.
  Locking torque: 6-8 N·M

  Excessive torque may damage the screw.
