Trying to install a Saint bottom bracket into the adapters that came with my Demo 8 frameset, but the drive side threads bottom out inside the adapter before I'm able to get it tight. I have one 2.5mm spacer on it now and I'm not able to tighten it. If I put two spacers on it seems like I'm able to tighten it down. I'm just afraid that it will put the drive side out too far and the non-drive side in too close. Anyone else run into this? Any solutions?
