The Lezyne Tool Insert Kit Large is an innovative hidden multi-tool that discretely and securely inserts into the opening of a handlebar. It’s constructed from lightweight, durable machined aluminium and features hardened steel tool bits. The kit is easily accessible for quick repairs and is available in three sizes with up to eleven different tool bits that suit today’s modern bikes. The end of the tool doubles as a bar end plug and comes with three O-rings that size the tool to fit securely inside most handlebar ends.
