Thule AcuTight Knob 528
A torque limiter accessory for rear mounted bike carriers with frame holders – replacing the standard knob.
The Thule AcuTight knob has a built in torque limiter that clicks when optimal hold is reached indicating correct mounting.
The controlled torque going into the bike frame prevents an under and over tightening of the holder.
Ergonomic soft grips.
Lockable with the Thule One-Key system and lock kit.
The Thule AcuTight knob fits all Thule rear mounted bike carriers with frame holders.
