Current stock: 0
  • Steel chainring adapter with 40 sprocket for the BBSHD
  • 130mm BCD
  • Steel Coated but Aluminum Material - lightweight with stronger finish
  • 316 grams
  • 2 pieces so you can use with other sizes of chainrings

  • The first ultra affordable chainring set for the BBSHD

The only negative complaint we have heard about the BBSHD is the ugly and heavy steel chainring.   

Luna is excited to offer its new custom aluminum chain ring adapter and sprocket set  that looks twice as good and weighs half as much as the stock ring. In additon this sprocket uses the latest in sprocket tooth technology to hold on your chain better, and offers a higher torque gearing for the BBSHD with its 40 teeth. 

This is not the piece of art that the $100 Luna Eclipse chainring is but serves the same purpose and saves a bunch of dollars. 

This chainring looks as good as any other chainrings (besides the Eclipse) on the market at a reduced price.

It uses extra thick teeth to grab your chain and for long lasting durability. 

The chainring is in two pieces so you will eventually be able to put other sized sprockets such as the 5 bolt race face chain rings. 

We are offering this set up at a very reasonable price at $59. Compare that to our competitors who sell similar set ups for well over $100.

Note: This does not have as much offset as the more expensive chainrings. If you foresee having chainline issues you want our Eclipse or Lekkie, or plan on reworking the cassette as described in our documentation

Perfect fit and the chain hasn't fallen off yet

My chain would fall off of the standard bafang chainring periodically. With this chainring the chain has yet to fall off.

Alternative Chainring

Purchased this so I could compare performance. The 3 sprocket assembly that I removed was 48-38-28. Most of my riding was the 38. The stock Bafang is 48. Got the 42, just in case. The Bafang 48 lined up perfectly but I am having trouble lining up the 42. It is much lighter and well made. More work needed with my 2011 Giant Cypress build to use the 42.
