Perfect for taking on every ride. Unique Park I-Beam technology is strong compact and lightweight. The I-Beam creates a structure to mount all the tools onto. 3 4 5 6 and 8 mm hex wrenches cover most fixings on a bike including many crank bolts. A straight blade screwdriver is useful for adjusting screws on brake and gear components. All tools fold into the I-Beam to create a neat regular shape that will slip easily into a jersey pocket or seatpack. A must have take-along tool for road and off-road use.
