Material: special tool steel, hardened and tempered

The wrench is designed for installing and removing Campagnolo® Ultra-Torque bottom brackets. The tool combines a wrench, bolt with nut, and knob. To use, place the wrench on the bottom bracket nut so that the bolt is inserted inside—this prevents the wrench from slipping and damaging the bottom bracket nut when loosening or tightening. Your work is made much easier thanks to the 350 mm knob with a two-component ergonomic handle. An additional element is a 19 mm drive for an open-end wrench or torque wrench. The tool can be used independently with a 19 mm wrench, without the bolt with nut and knob.
