I've just installed 2008 HTII cranks into a RaceFace DH X-Type BB (because the BB cups have twice as much thread-width as the Shimano BB cups), but the Shimano BB that came with the cranks only came with three 2.5mm spacers (not three different sizes).

Also, I deliberately omitted the recommended 2.5mm spacer on the drive side, putting it on the non-drive side instead. This was because I previously stripped the BB frame thread on the drive side, and I wanted to reach undamaged thread, but then I found that I actually got a better chainline (50mm) as a result. The Shimano recommended chainline is 47.5mm to 50mm, I think.

Admittedly, when the front mech is in the position for the granny ring, it's a fly's tadger away hitting the frame, but I've managed to adjust the screw to protect the frame. It only just changes down though, it took a lot of careful setting up otherwise the chain would stay on the middle chainring.

Steve.
