Read electric-fatbikes review of the Mighty Mini

• 30 teeth
• We feel a more ideal gearing than the stock 46 tooth chain for ANY type of riding
• Increased torque significantly without much loss in top speed
• 7075 heat treated alloy for durability and lightweight
• Plated clear coating to resist corrosion
• Single piece design
• Ultra lightweight for those rare ebike weight weenies
• Lovingly machined in California by Luna cycles

This 30 tooth sprocket really brings the BBSHD to life.   

On our test bike we were able to get to 32mph with incredible torque compared to the stock ring where we got to 34mph (got there very slowly) so for a sacrifice of just a few mph in top speed you will get tons more torque. This chainring is perfect for offroad use. 

Because of its wicked tooth design the Eclipse clings to the chain and will keep the chain from falling off on even on full suspension bikes. Our test bike was a full suspension bike which had many issues with the chain falling off with the stock steel Bafang chain ring but this ring we had no problems despite its small size. 

This chainring was reviewed very favorably by Karl from electric-fatbike.com (review here) for singletrack riding with a BBSHD.

NEW 36T version of this chainring is now available at this listing

Support notes

This chain ring unlike our standard Eclipse chainring only has a very mild offset so it does not do much to correct the chain line of the BBSHD. The same is true of all chainrings smaller than 42T.
Unless you have a wide fatbike you will likely want to use an IGH or rework the cassette in order to have a good chainline through all gears, otherwise you may have shifting problems in lowest gears.

See our Knowledge Base for a comparison of this chainring's offset compared to others

See this link for our documentation on reworking the rear cassette.

This ring works best with 10spd chain and lower

For single speeds we strongly recommend this to be used with a derailleur type chain tensioner. If you don't use a chain tensioner and the chain does come off you risk bending the ring when you put it back on. If the chain comes off put the front chainring on first then put the chain over the top of the rear cog and slowly roll the bike backwards. Stop pushing if there is too much resistance. If you put the cog on first and then try to put it on the front ring it will bend or break the teeth and your chainring will not work right anymore.
