The Y tools are a new take on the traditional multi tool. Designed to offer shop quality tools you can take on the road or trails.The 2 Y tools are held in their carry frame due to their magnetised centres. Like with the Y-12 tool there is a compartment containing 6 bits which can be used with the driver on one of the Y tools. In addition there is a CO2 inflator and a chain breaker. The chain breaker is used by inserting the 8mm in the bottom of the chain breaker and the second Y tool is then used as the handle to unwind the pin. You get great leverage and grip making chain repairs on the trail a little less frustrating.Weight: 260gWarranty: LifetimeDimensions: 89mm x 94mm at the widest pointsY tools: 3mm, 4mm, 5mm, 6mm, 8mm and bit driverCO2 inflator - threaded cartridge compatibleChain breaker - compatible with 8/9/10 and 11 speed chainsBit compartment: 2mm, 2.5mm, 1-phillips screwdriver head, 1-flat head screwdriver head, T-10 and T-25 torx keys.
