Fix MFG Mtb Field Kit One Color, One Size

The MTB Field Kit is the perfect solution for those scenarios where we need the tools from our garage, but we're already at the trailhead for our ride. We keep it in our car because it has all of the tools we need to keep our cockpit dialed, our suspension properly tuned, and our chain lubed up. It even includes an MTB field guide as a place for us to note our sag, air pressures, and rebound clicks for our suspension.
