PASS QUEST 2X CHAINRING

• The F107BCD 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.
• Smooth Shifting: We conducted over 30 experiments—patiently refining the tooth profile, the placement of the up-shift pins, and the orientation of the down-shift ramps—ultimately earning the seal of approval from numerous expert testers.
• Anodized Surface: 7075 aluminum alloy is a particularly challenging material to anodize. To address this, we conducted multiple rounds of prototyping and ultimately selected a Taiwan-based manufacturing facility to ensure the highest quality anodized finish for our chainrings.
• Lightweight Design: To optimize both weight reduction and rigidity, we have subjected the chainring to extensive hollowing and chamfering processes.
• Ensuring its lightweight performance remains far ahead of the competition, this chainring features a uniquely shaped pin design to deliver exceptional chain-catching capabilities, thereby significantly boosting shifting efficiency.
• Countersunk Structure: This design enables precise positioning and increases the contact area with the chainring; furthermore, it results in a cleaner installation aesthetic and effectively minimizes extraneous noise.
• 107BCD for Force crankset only. 
• 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.
• We provide standard screws free of charge.
  Locking torque: 6-8 N·M
  Excessive torque may damage the screw
  
• Installation Instructions:
  1. Position the large chainring pin directly beneath the crank arm.
  2. Align the positioning point on the small chainring directly beneath the crank arm.
  3. Align the countersunk holes with the chainring bolts to complete the installation.
