I have both sets here and physically they look very similar, they are stamped differently. The 91412 (lite & B5)arm does not have the cut out that the 91528 (Team & CE) arm has, aside from that they appear to be the same
What is the difference???
VERY little difference, the B5 arm moves the hub forward either 1 or 2 mm. Not much but it does give a lil bit more rear traction. That's why most ppl were putting them on early on. I did on both of my B5M's.
