Accurate & Easy to use Torque Wrench Applying the correct torque to your cycle components is essential for a safe & serviceable bike. This accurate torque wrench helps you ensure that the fittings on your bike are tightened to the correct torque & that clamping forces are distributed evenly across clamping surfaces. Hex Keys & Torx Keys Included This helps prolong the life of high-end components & prevents damage from over tightening. X-Tools also include 3, 4, 5, 6, 8, 10mm hex heads, T25 & T30 Torx heads, & an extension bar for reaching concealed bolts. This makes it absolutely ideal to be used on stems, seat clamps, lever clamps, chainsets, rotors & headsets.
