So, I started commuting to work three years ago. Then last year we adopted another dog and I take her our mountain biking regularly. Just before Christmas I started wrenching my own bikes. I wound up building up new wider rims and a drive train on my MTB. This meant I needed a new pair of tires. Then I put an Alfine 11 and a front disk brake on my commuter. I regularly clean my drive trains and fiddle with stuff. Accessories, tools, and parts of various applications are all over my shed. Now that my MTB 1x9 setup is showing signs of wear I want to put an Alfine 8 on it and set it up for adventuring, touring, and bikepacking, and of course buy yet another pair of 26 inch tires. I think my wife wants to kill me. Is this a normal obsession? And should I find another hobby? Should I try to make some cash on the side with this?
