one reviewer said:
"Does exactly what it's supposed to. Fitted a new cassette (having never done it before) and it couldn't have been easier. I was unsure how much to tighten the lockring but the wrench has a kind of built in torque wrench; when you reach a certain level of torque the tool 'slips' so you don't over do it. Thoroughly recommended."
What does he mean with 'slip'? Anyone with a same (or similar) tool would like to share if this BBB BTL-12 tool really has a 'built-in torque wrench'? Because it does, then I will just buy this one... will save me heaps of money rather than buying a separate torque wrench and a lock-ring tool.
