We tried Speedway

colnago never have made a fillet brazed frame, nor anything in 531.
fact! it is a british frame, made for british speedway, can't remember the builder (possibly from pearly way around croydon) who did the so called triple triangle for these.....but i will

It was made by Ernesto himself after a visit to Sheffield, the finish is Pearlescent Blue, which is proably why you're confused, BTW hope you didn't lose your Rolla tee shirt on the way home!..Also I can see five triangles....maybe even more.
