A few key changes have been made to the equipment setup since Montana. Here, and below, you'll see that we have added a structural framework around the Picarro Instrument to protect it. In addition, there are shock absorbing rubber spacers fitted between the framework and the instrument itself. This will hold the two pieces of the instrument together firmly while it sits inside the saddle bag. On the left you see our first shot of the wheels that will be used to hold the gas sampling inlet tube close to the ground. These are essentially bike training wheels without the bike.
