Please post your BBSHD Chainring Inset measurment(s)

[g725s]

I would like to propose that BBSHD chainring owners post their BBSHD Chainring Inset in this thread. If you can post a picture that would be great also. I would like to ask that you keep discussion to a minimum, keeping this thread mainly a place where Chainring insets for the BBSHD can be found. I could be incorrect here, but I'm calling it "inset" over "offset" because I see it as inset toward the bicycle frame.

I propose that we measure the Inset in the following manner as I show in the photo below for the Stock BBSHD chainring. Lay a straight edge across the chainring as shown below, and using a machinist ruler, or similar, measure (preferably in Milimeters) the inset to the actual mounting surface of the faceplate:

I got 18.3mm for my stock steel Bafang BBSHD chainring.

Please post your inset measurement for all the various chainring and chainring adapter variations available for the BBSHD

For the Luna Eclipse using the same measurement method above I got 24.72mm inset:

As you can see 24.72mm is .68mm under 1 inch. I could not find my small Millimeter ruler so used the imperial ruler that I had then used the calipers to get Millimeters as in the picture link in my first post here. And I would say my measurement of the insets posted here are at most .02mm off.

If anyone has the Bafang Alloy chainring adapter, the Lekkie 42t HD, and a BBSHD California Ebike chainring adapter with a chainring installed, I would really like to know your inset measurement of these

This is the Luna 42 tooth ring

It has 8.57 mm of offset.

Luna cycle has a YouTube video with insets for several chainrings. Sorry, too hard for me to post video on my phone.

All the BBSHD chain rings Luna offers!

And an even more accurate and proper way to measure using a dial indicator the Bafang Alloy Chainring Adapter is 8.57mm inset
