Metal Guru

Metal Guru is a resource for both hobby and professional bicycle frame builders.

The frame building raw materials, tools and components we carry in our store are a curated collection. Each item is selected by Carl "Snarl" Schlemowitz, founder of Vicious Cycles, with the criteria that he would personally use it as part of a frame build. We stock a wide selection of Columbus tubing and frame kits, dropouts, lugs, bottom bracket shells, consumables, tools, components and more, as well as custom parts from Metal Guru.
