The Profile Spline Drive Spider is machined from billet aluminum plate and supplied with a CrMo steel adapter insert already pressed in. It works with 4-bolt, 104mm chainrings and has a 19mm bore. This will fit 3-piece cranks that have 48-spline, 19mm spindles.
Color: Red
Manufacturer's Note: This Profile Racing component was colored by anodizing. Anodizing is how we dye the metal. We make every effort to color match all anodized items, color shades and small color differences do occur. This is not a flaw or imperfection, but it is inherent to the anodizing process.
