Just got a BBS02 for my GT Aggressor Pro. I had to grind our the cylinder for the bottom bracket. Finally got it seated all the way in and now the stock Bafang 44T chainring is 2mm away from the chainstay. The chain line looks perfect. Just wondering if that’s too close? The motor is also very close to the frame, about 1mm. Should I be concerned and shift it over with a spacer or 2? Thanks.

if its 1-2mm off the chainstay and you can hit all the cogs in the cassette without any touching on the frame, you are done. having a few 2.5mm motor spacers and one lekkie 2mm spacer is a good idea in case.
