Prepare for Hell Niño — $20

Brand-new rear bike rain / splash guard. I never used this because I only needed the splash guard for the front tire.

May work on the rear wheel too.

Comes with 4 straps, which allow it to fit to most bikes. Medium–narrow guard width is best for road bike tires or medium width tires.

Take precautions against this winter's inundation: Don't get your lower back drenched in mud on the way to that big interview at Palantir.
