Jenson says Spindle Length: 111, 115.5 mm(170mm), 111,116 mm(175mm)... so if you get the 170 mm cranks u need the 111 length BB.

Whats the reason the LBS said no to use your BB??? Japanese frames almost all the time come with an english BB shell, is your veloce bb english or italian threaded? is just a thing of reading what it says, second thing is that those veloce BB as the one u have generaly come in 111 mm. Maybe the guys did not have the tool to put the BB in place********** Veloce uses a special tool because the notches arent squared, are knd'a crescent shaped.
