Not just any XCr tubing, this is the first ever frame to utilize the famous Columbus Max profile tubeset in XCr. We call it Firefly MegaMax because it is based on the Max profile but uses larger diameter tubing to better take advantage of the properties of XCr.
The down tube starts as a butted 38mm tube and (like the top tube) is bi-axially swaged into opposing ovals. It is ovalized vertically at the head tube and horizontally at the bottom bracket. The vertical oval at the head tube makes for the strongest possible non gusseted TIG welded joint at the most heavily stressed area of the frame. The horizontal oval at the bottom bracket adds considerably to the lateral stiffness of the frame while sprinting, stiffens up the bottom bracket, yet doesn’t detract from the compliance or feel of the revered XCr tubeset.
Double wet dream- Columbus XCR Stainless PLUS MAX profiled tubing!!
