I always worry a bit when I go to do maintenance on my bike, but after watching enough youtube videos and reading enough articles, I gain the confidence to do it.

It might take me longer the first time around, but I'm usually pretty successful.

I just had a friend that took her bike into the shop to get a flat tire repaired. I was flabbergasted. I told her to bring her bike over this weekend and I'd show her how to do it. She's quite excited.
