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.

Like everything SILCA do, the Ypsilon was designed by a team of engineers and mechanics who obsess over every fine detail. Unlike traditional Y-wrench designs, Ypsilon is customizable and adaptable to the mechanic's preferences. SILCA were able to do this by using a ¼" bit collet with magnetic attachment in place of one of the 6mm hex wrench. This departure from the traditional Y-wrench design was inspired by the versatility of the T-Ratchet + Ti Torque kit, and means that Ypsilon can easily transform into any tool you need simply by swapping out the bit. The other two ends of the tool are 4mm and 5mm hex keys.

Another key benefit of Ypsilon is the tight tolerances of the keys and bits. Tighter tolerances mean a better tool fit which drastically decreases the likelihood of rounding out fastener heads. These tight tolerances, combined with the CrV steel spine of the tool make Ypsilon incredibly durable. A lightweight composite body with ergonomic grips provides good comfort and control with the contact points of your hand.
