Instead of using a heavy metal brace to hold the individual drums of Ludwig Marching Tenors, they've collaborated with Randall May to create Free-Floating Lug Bridges. By connecting the drums to each other with high-strength polymer brackets on the lug casings, they've reduced a significant amount of weight.
This set includes all of the lug bridges you'll need to connect outer 10-12-13-14" drums together (regardless of quad, quint, or sextet configuration). Bridges to connect spock drums are sold separately.
