Dislike thin chains, they wear out at least 3 times faster then the old wide chains.
Dislike not being able to get small parts to fix components.
Dislike threadless headsets.
Dislike bike frames going for the lightest frame possible only to have short frame life expectancy. Dislike drivers who just have to treat cyclists like their gnats in their way.
Dislike working on new bikes, older bikes were much easier.
Dislike all this black carbon component crap, I like shiney stuff like chrome or polished aluminum.
Dislike bikes without lugs.
Dislike all this cycling stuff coming out of China.
Dislike snow because I hate the trainer.
I like the smell of burning rubber off my tires, dislike that my bike can't do that!
