Went for a ride. The bike felt like hell. Really slow and sluggish, kinda dead feeling, yet harsh and chattery at the same time. Going around corners felt nervous, sketchy and wallowing all at the same time. WTF could cause these conflicting sensations. Especially after setting the pressure to EXACTLY my well established favorite PSIs? I went home. Checked spokes, wheel bearings, looked for frame cracks, couldn't find a single problem. Then It dawned on my, my air pressure gauge must be malfunctioning. So I checked the tires with a different gauge and sure enough the pressures were whacked out. Miles out of the ballpark. How could my nice new gauge give two severely false readings that seemed reversed from what they should be?

Defective pump operator. I aired the front to 70 and the rear to 45. F'ing space cadet knucklehead.
