Since you are presumably putting Shimano cranks onto a Shimano cartridge, you should have no problem, but this is a heads-up for those with older European cranks, which will not seat all the way onto most Shimano spindles.
oy, more i have to worry about, this is all new to me. i'm using takagi cranks. takagi was a japanese crank mfr back in the 80s. i would hope they followed the standard JIS taper (is that the 2-degree standard you were referring to?)
