This is an awesome bit of kit for those riders that like to carry as little as possible. The Lezyne Storage Drive Tool is a compact option for those chasing the basic bits. A 4, 5 and 6mm Hex key and two Torx heads T25 and T30 are included in the unit and are stored in the handle for easy access. It comes with a strap for mounting on the bike or you can pop it in a backpack. Made from machined aluminium you remove the handle select your bit and then use the integrated magnet to hold tool bits in place.
