  • Aluminum chainring adapter with 42 sprocket for the BBSHD
  • 130mm bcd
  • 220 grams is less than half the weight of the steel bafang sprocket
  • 2 pieces so you can use with other sizes of chainrings
  • Designed by Luna
  • Lightweight 
  • Wicked tooth profile to hold your chain on
  • Anodized black
  • The first ultra affordable chainring set for the BBSHD
  • This chain ring only has 10mm offset. 


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 more ideal gearing for the BBSHD with its 42 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 sale 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.

Hold chain well

Well constructed chainring. Holds the chain very well with the wicked tooth profile.

A thing of beauty

I got this in case I had chainline problems but didn't end up using it myself. Sold it to a mate who loves it. They are extremely well made and the silver one is pretty blingy indeed.
