Silca has taken the compact and handy layout of the y-wrench and improved on it with the completely new innovation of a customizable 3rd bit slot.
The Ypsilon (pronounced ip.si.lon) is Silca’s take on the unassuming y-wrench. Pro mechanics, bike shops, and avid home mechanics have long preferred the layout of this tool due to the ergonomic benefits that make it more convenient and more enjoyable to use. 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.
