Today was my second commute. Cloudy and cool - around 60 when I left home.
I re-learned a valuable lesson this morning - don't mess with the bike the night before and not test ride it first before taking it in to work. I had installed an adjustable stem for the handlebars and now the whole front fork vibrates every time I hit a bump. I know I had that thing tight so I'll have to check it out before I leave tonight. I'm SO glad I tossed a couple of tools in the bag last night.
