           PASS QUEST NARROW WIDE CHAINRING

  • The Shimano chainring is made of a single piece of aluminum plate, CNC milled. The back is hollowed out and chamfered to ensure strength while reducing the weight of the chainring! The chainring uses an extended tooth shape, and the teeth extend far beyond the chain, so even if the chain jumps violently, it is not easy to fall off the teeth, thus preventing the chain from falling off.
  • ①boost Frame selection 3mm offset
    ②142Frame selection 6mm offset
    ③ Choose when you need a large number ofteeth, worry about the frame,and expect a cheap price 0mm offset
  • Our tooth height is 8.5mm
    The teeth extend far beyond the chainWhen you jump like crazyThe 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 
  • The chamfering design can reduce the weight of the gear plate and make the gear plate more beautiful
  • Narrow wide tooth, it design for 1x speed only, can not use as 2x speed, not support front shifting derailleur.

Looking for top-level professional cyclists

This is the new equipment for professional road bikers, track bikers, and time trial riders.

We designed and manufactured a 5mm thick narrow-wide chainring, increasing lateral stiffness and featuring a high bracket density. It weighs about the same as a carbon fiber chainring with the same number of teeth, but is much stiffer, making it suitable for riders with higher power output.

Our single-speed chainring has also been optimized and upgraded.
