Difference between standard Nagano and VS or LB blades

What is the difference between a Nagano LB and VS tube?

Viking only produces standard sizes of Nagano skates. Very occasionally an exception was produced at the request of top sport or specific skaters. Viking has always tried to meet skaters in all wishes and of course tested a lot with skaters for innovation and in bringing new products and still does. See in the overview the length differences between the Standard Nagano tube (version B) and the different versions Nagano Extended steel and Longer tube, or in rare cases both.

Nagano LB stands for Longer tube

Nagano VS stands for Extended Steel
