Silca Ypsilon Wrench
Silca Ypsilon Wrench, The YPSILON (pronounced ip.si.lon) is SILCA's take on the unassuming Y-wrench. Most tools in this layout feature 4mm, 5mm and 6mm keys; meaning that the wrenches for some of the most common use cases in cycling are readily available in one tool. The shape of the Y-wrench also offers superior control and stability over traditional hex keys, especially in tighter work spaces.
