Default Re: Help! Dax shift kit, SBP BB adapter, crank has play!

After googling for a while, I came to that same conclusion, at first. But when I went to measure the BB tube to confirm, I came up with 68mm. Unless I'm measuring wrong. Its just the tube, without the adapters that I'm supposed to be measuring, right?

Like this?:

Or is it from the outside of the adapters? If so then I get 74mm.

Thanks for your help, Ghost. (Truth be told I'm already regretting not buying my shift kit from you guys. I've been using your instructions this whole time since Dax includes no instructions with his kits and his video instruction series appears incomplete as of yet...)
