The Coin driver Stubby from PB Swiss Tools with the famous SwissGrip handle, is perfect to remove battery covers, plugs and plastic screws. A lot of cycling electronic devices are powered with a CR2032 coin battery. The PB Swiss Tools Coin driver stubby gives you a firm grip and allows you to accurately apply the correct torque on the battery covers, while minimizing the risk of damaging these plastic battery covers.
The PB Swiss BikeTool is a clever designed multi-tool for on the go, and I will compare it with my Lezyne V10 multi tool. The PB Swiss Tools 470.M Adapter is part of this 1/4″ bit based BikeTool. The adapter is 1/4″ bit holder that can be used in combination with a 5 mm. hex/allen key.
Furthermore I will share my thoughts on why every home mechanic should have the PB 470.M Adapter and a set of PB Swiss Tools allen keys.
