I have a 97 Tetra and when using a 9sp DA crank I used a 112.5mm XTR spindle in a Italian DA BB.I still had to use a 1mm spacer to get clearnace.I switched to a carbon FSA crank and was able to remove the spacer.I now use the mega exo BB with FSA compact and there is plenty of room.Dave Thompson might know if the spacer will work with a 109.6 spindle?
