Innovative concealed mountain bike multi tool that discretely and securely inserts into the opening of a handlebar. It’s constructed from lightweight, durable machined aluminum and features hardened-steel tool bits. The kit is easily accessible for quick repairs and comes with five (small), eight (medium) or 11 (large) different tool bits ideal for today’s modern bikes. It also doubles as a bar-end plug, and comes with three differently sized O-ring fasteners to ensure a secure fit inside most handlebar openings.
