The NEOS Pre-Set Torque Sleeve is the perfect tool to prevent over tightening and damaging your carbon components. Simply put the sleeve in position on the tool of choice and then insert your required bit into the torque sleeve. Tighten as usual and at the pre-set tolerance the tool will simply slip in the sleeve thus making it impossible to over tighten the bolt or screw you are working on. These are a great investment for anyone with any carbon components on their bike requiring any of these pre-set tolerances. In the NEOS range, we currently have 4Nm, 5Nm and 6Nm with 3Nm due in soon.
