If you can handle digital navigation, you will never go back to a paper map. However, there are some downsides I have to cope. Firstly the limited accumulator power, easy to solver with a power bank, or second phone. More serious is a rainy day, my waterproof smartphone couldn’t stand raindrops following on the screen and got crazy. The watertight case was unsuitable either hard to deal with or fogged up. A simple homemade device is currently the solution. The overall advantage, I get every information I need, offline or online, on a fingertip.
Sometimes there might be some trouble during a trip, usually minor things such as puncture, brake adjustments or gear shift corrections. I always have the tools and a few spare parts with me so I can handle these matters. However, in 2014 I was permanently challenged by chain failure. The new chain has split up every few days. First I used my reserve pin, later I shortened the chain after each incident, at last, I bought a new one. Then I learned that certain chains only link with the original brand chainlink. Conclusion, sometimes I’m challenged by strange technical issues.
