Preset Torque Wrench

Preset wrenches are designed for simplicity and reliability. Because they are calibrated to a specific torque limit at the factory, there is no risk of user error or calibration drift that can occur with adjustable models, making them ideal for specific, repetitive tasks like tightening stem bolts or seatpost clamps.

No, this tool features fixed 4mm hex and T25 bits. It is designed specifically for the most common adjustments on modern bicycles, so you cannot change the bit size.

You should always check the manufacturer's specifications printed directly on your bike components. Most carbon fiber parts, such as stems and handlebars, will have the required torque value laser-etched near the bolt holes.

Yes, this tool is specifically engineered to prevent over-tightening, which is the primary cause of damage to carbon fiber parts. By clicking out once the preset torque is reached, it ensures you apply the exact tension required without crushing delicate material.

When you reach the specified torque, the wrench will provide a tactile click or 'break' feel, indicating that the bolt is properly tightened. You should stop turning immediately once you feel this release.
