We can read your mind. You want a tough multi tool that's light enough to let you forget all about it until you need it. Lezyne also read your mind, and came through with the V 5 Multi Tool. The V 5 uses ultra durable nickel plated chrome vanadium bits and a lightweight 7075 aluminum frame to answer all your prayers or at least one and keep you rolling, even after your bike has tried to strand you miles from home. Lezyne uses nickel plated chrome vanadium bits to make sure you have the toughest tool possible. The CNC machined bits are unbelievably precise, so you don't have to fight to keep them from rounding your hardware. They'll never rust, either, even if you forget them in your pack over the winter. In order to keep weight down, Lezyne uses CNC machined 7075 aluminum side plates and a forged and CNC'd chain breaker. The most important difference between the V 5 and most other multi tools is Lezyne's clever center pivot bit design. This design allows Lezyne to make low profile tools that are lighter, stiffer, stronger, and more ergonomic than the more common wraparound design. Look closely at the joint area of each bit. The center pivot design keeps the axis of the bit in line with the plane of the tool to make it feel more like a full size tool. The natural feeling pivot point is more comfortable and it gives you more torque. The Lezyne V 5 Multi Tool includes the tools that you need for the most common road and trail side adjustments and light repairs. 90% of the time you're making adjustments with Allen wrenches, and Lezyne includes the most common sizes: 3, 4, 5, and 6mm. The Phillips screwdriver comes in handy more often than you'd think just take a few rides without one, and we all know how annoying it can be to be caught miles from home with a broken chain and no chain tool. All that in a tool that weighs less than two ounces!
