The Problem Solvers Direct Mount Adapter gives you a place to install direct-mount Shimano and SRAM derailleurs. It was initially developed for standard mountain bike frames with 68/73mm wide bottom bracket shells, and is equally suited to fat/snow bikes, where their 100mm wide bottom brackets make front derailleur applications a little difficult. The adapter is made of light and durable 6061 aluminum.
