Easy to Use: The bicycle torque wrench is equipped with a quick adjustment mechanism making you change the torque value smoothly. And a "Click" sound can clearly tell pre set torque value reached. There are clear Nm read-out scales in the handle, easy to read. One Set for All Needs: Bike torque wrench set includes a 1/4'' Drive Torque Wrench, 6 hex bit (H2, H2.5, H3, H4, H5, H6), 4 Torx/star bits (T10, T20, T25, T30), a 1/4inch*4inch extension bar, 2 sockets (8mm,10mm), and a storage box. A great set for your bicycle or motorcycle maintenance. Quality Guarantee: The 1/4" torque wrench head is made of chromium-molybdenum alloy (Cr-Mo) steel, with higher strength than chromium-vanadium (Cr-V) steel. Aluminum-titanium alloy handle ensures a comfortable and anti-slip grip. Premium spring-loaded adjustment collar can be locked at the settled torque value automatically, which ensures stable working. Accuracy Guarantee: Over tightening or over-loosening torque highly causes bolts out of their job. Therefore a high-accuracy torque wrench is always needed. Our drive click torque wrench has a 1-6Nm working range with micro-adjustment to 0.05Nm, which helps you to set the expected torque value as needed. We also made tests on each of our bicycle torque wrenches to make sure pre-calibrated to an accuracy of ±3% (Normal torque wrenches only at ±4% )., Manufacturer: QAXRZCUCD
