Topeak created the Ratchet Rocket Lite DX as a nifty little package for tightening loose bolts and components on your bike and even common household items. It comes packaged in a nice little nylon case, which is easily stored in your garage workspace or even carried in a pack when you need tools close at hand. The fine tooth ratchet mechanism features a reverse lever and thumb wheel for controlling it in those tight, hard-to-reach locations. This kit includes hardened steel bits for years of longevity on your favorite bike. Specifically, you'll find 2, 2. 5, 3, 4, 5, 6, and 8 millimeter allen bits, T10 and T25 Torx bits, and #2 Phillips screwdriver, as well as two plastic tire levers and magnetic bit holder.
