Since there are several versions of the Alpina cranks we asked Sugino to make the best possible model for us. Of course, we wanted cold forged polished silver arms. Sugino also makes numerous grades of chainrings and we speced the finest available, CNC cut chainrings with all the shifting aids for 9-10 speed chains (though they work perfectly with 5-8 speed as well). Then we asked Sugino to polish the rings! The result is this lovely VO-spec Alpina. 48/34t rings, $165; square taper JIS 110mm BB; Q-factor is around 160mm, about 665gm.
