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.For cyclists and mechanics alike who obsess over every fine detail and desire a versatile Y-wrench.
Ypsilon was designed by a team of engineers and mechanics who obsess over improving products. The body of the tool is constructed using a composite polymer with soft over-mold grips. Unlike traditional Y-wrench designs, YPSILON is customizable and adaptable to the mechanic’s preferences. This is accomplished by using a ¼” bit collet with magnetic bit attachment in place of a fixed 6mm hex. This departure from the traditional Y-wrench design was inspired by the versatility of our T-Ratchet + Ti Torque kit. The YPSILON can easily transform into any required ¼” based tool by swapping out the bit.
