Hello.

How did you glue it? I have tried to find pics on Google but can't see it.

Just sand it, add epoxy and put adapter in.

I didnt understand at first. You mean the adapter inside the frame.

Thank you very much!

Thanks for the reply!

I think I am going to buy this option. It is available on Amazon in my country for 25 euros (the 2 units). The other option I like more, but it is 70 + 20 shipping cost.

I am going to think about it this weekend but if you are happy with it... It is fine for me.

By the way, in what bike did you use it?

Hi, I'll try a similar conversion, having a 100mm bafang motor and a bb92 bottom bracket. I found these Cyc bb92 to bsa adapters, has anyone tried them? FasterBikes.eu | BB92-BSA adapter cups

Strangely my bike bb widht is more than 92, more like 95mm which should make it even easier as I'll only need a few mm of bsa washers for a tight fit. My plan is to glue the adapter with epoxy to the frame because they have a lip on which the motor lockring will hold so I need them firmly attached to the frame.

I'll be very grateful for any feedback and opinions.
