It's more important than ever to tighten bolts to the recommended spec, seeing the prevalence of carbon bikes and components on the market, which are susceptible to cracking and crushing when over-torqued. Dial in your custom build or new components to the exact torque specs with the Pedro's Fixed Torque Driver. Each driver tightens your bolts to a precisely calibrated torque figure, so you can be sure you're not over-torquing key bolts on sensitive areas, leading to crushing of handlebars or cracking your frame's seat tube. The Torque Driver accepts 1/4-inch hex bits with its magnetic socket and includes 4mm, 5mm, and T25 bits. Choose 4, 5, or 6 Nm torque wrenches to suit your needs.
