OVAL CHAINRING ADVANTAGES

  • 110-5BCD is made of a whole aluminum plate by CNC millingThe back is hollowed out and chamfered to ensure strengthwhile reducing the weight of the chainring. The chainringadopts an extended tooth shape, so even if the chain jumpsviolently, it is difficult to get out of the teeth,so as to prevent the chain from falling off.
  • Multiple muscles are responsible for the balanced output
  •  More stable
  •  Give full play to the strength better and steadily
  •  It is more convenient to shake the bicycle
  •  Suitable for long distance, more effective to maintain their physical fitness
  • Our tooth heightis 8.5mm.The spacebetween teeth is much larger than the chain.When you jump wildly, the chain will jumpviolently and it is difficult to get out of thespace between teeth. This will trulyprevent the chain from falling off
  • Manufactured using 7075-T651 highly durable aluminum alloy
  • The chamfering design can reduce the weight of the gear plate and make the gear plate more beautiful
  • For Sram Red Rival S350 S900 Rotor Force 110 BCD 5 Bolts
  • 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.

  • Locking torque: 6-8 N·M

    Excessive torque may damage the screw.

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.
