The Metro spline drive sprocket is made with the same precision as the regular version, but features a hardened cromo 48 spline / 22mm splined insert for people who want to do away with their sprocket bolt, and for those who want to run LHD on the United ‘Nash’ cranks.
(This sprocket will work with any traditional 3pc 48 spline / 22mm spindle cranks as well as LHD only on the Nash Cranks due to their 2.5pc system)
