Using the Blackburn Compact Mini Switch Multi - Functional Tool for Bicycles is a breeze. First, find the right bit for the job from the switch double bit sticks. The 3/4mm, 5/6mm, and T25/T30 double bits give you a good range of options for most bike maintenance tasks. Just pull out the needed bit and start working on your bike. When you're done, simply put it back in its place. As for storage, take advantage of its slim profile and lightweight TPR sleeve. You can keep it in your pocket when you're out for a short bike ride, or toss it in your bag for longer trips. To keep it in good shape, make sure to wipe it down after use, especially if it gets dirty or wet. Avoid using it on jobs that are way beyond its capacity, as this could damage the tool bits. With proper use and care, this multi - tool will serve you well for a long time.
