Silca Ypsilon Y-Wrench and Bit Driver Tool

A must for your shop apron pocket in the garage, on the road, or in the pits at the cyclocross races. This is Silca's improved and upgraded version of the classic "Y-wrench". Features 4mm and 5mm hex, plus a 6mm hex bit on the 1/4" bit collet with magnetic attachment, so you can swap in any standard bit to meet your specific tool needs.  Designed for the home or professional mechanic who obsesses over every detail. Offers improved control and stability compared with traditional hex keys in tight work spaces.  Inside is a high-strength CrV steel spine, covered with a comfortable, composite polymer body with ergonomic grips.
