Exclusive MITO Graphene Technology

Graphene is a single-atom-thick honeycomb layer of carbon, harder than diamond, yet more elastic than rubber. In fact, it’s the strongest and stiffest material known to man. St. Croix had an eye on graphene for a while, but until recently, available graphene products applicable to rod building failed to deliver the consistency and control they demand.

Through an exclusive relationship with MITO Material Solutions, St. Croix is the only rod manufacturer leveraging MITO technology and applying the first and only verified functionalized graphene product to its rod-building materials in-house. “Functionalized” means that MITO’s graphene product fits within St. Croix's existing manufacturing processes, and that they're in full control of the material’s application. MITO functionalized graphene is fiber-agnostic, meaning it’s compatible with any carbon or composite material they want to use – a critical consideration, as most of St. Croix rod-blank designs contain multiple materials. MITO’s formula also ensures graphene concentrations in the functionalized product are homogenous – much more evenly dispersed than in commercially available graphene nano resins. This means they're able to apply a total weight loading of actual graphene material at accuracies within .01%.

For the benefit of anglers, MITO graphene technology allows St. Croix to make certain sections of a fly rod blank stiffer and stronger while using less material, helping fine-tune flex characteristics while improving any rod’s overall strength-to-weight ratio. It also allows St. Croix to make fly rods with dramatically improved dampening for quicker recovery, translating to higher line speeds and greater loop stability. Finally, MITO graphene increases torsional rigidity, attenuating blank twist to keep the rod moving and flexing within a single plane for increased accuracy.
