While cleaning my cyclocross bike off after our trip to Acadia, I discovered a neat little trick using compressed air. I had taken the crank off because I’m still trying to get it adjusted right in the bottom bracket. Without the crank in, I decided to use a can of compressed air to blow a bunch of sand and grit out of the seat tube. Woohoo! Look at what happened. Pretty cool, huh? It totally reminds me of a steam engine. Yes, I’m easily entertained.
