Cycling requires specific tools, but unfortunately, the tool cases, bags, and boxes you find at hardware and automotive stores are designed for homegarage applications. That's where Topeak steps in with its PrepBox a well thought out case with cycling essentials like a torque wrench, bottom bracket tool, chain tool, cassette tool, and cable cutters. Instead of searching through the bottom of a tool bag, the PrepBox's plastic case smartly holds its 18 shop grade tools in place. Topeak uses chrome vanadium steel and hardened steel throughout for durability and long lasting performance with its tool. Also, ergonomic handles and comfortable grips keep you wrenching late into the night. Topeak's PrepBox measures 15. 9 x 12. 6 x 4. 5in for compact storage in your auto or home shop.
