Park TW-6 Large Ratcheting Click Type 3/8 Drive Torque Wrench
The TW-6 is for the bigger jobs.
12-60 Nm range makes it perfect for suspension linkages, cassettes, pedals and bottom brackets.
The smart head uses a 3/8" drive and will ratchet and torque both left and right threads. It's calibrated to just +/- 4% and uses a dial adjusting system in .2Nm increments so you can always get the right torque.
This torque wrench is 38cm long and comes with a nice tough case.
