The Lezyne Tool Insert Kit is a compact multi-tool designed to live inside your handlebar — out of sight, out of the way, and always with you. The tool bits are built from steel for durability, while the body uses aluminum to keep weight down. It's a practical alternative to stuffing a multi-tool into a jersey pocket or saddlebag. Lezyne offers the Insert Kit in three configurations — five, eight, and eleven bits — so you can match the tool to how much coverage you actually need on the road. Each version includes hex wrenches, Torx bits, and a Phillips head driver, covering the adjustments you're most likely to need mid-ride.
