Nineteen or Eighteen?

Whoa, this video is out there, funny what triggers a song. Is it Alice Cooper... Y/N??? Biking: Removed shifters & multi- gears off geary 29'er. Result 19 pounder. At Hillside race last Thursday, hotlap w/ 38x18, 2nd place. 19t would-duh worked better. Hmmm, what to run at Chequamie. Thinking it's 38x17? 44x19? 44x18? On a completley separate note. Alta, appendice taken out today! We are in the hospital recovering fine.
