Challenge Tire Pressure Mug
Keep calm and blame the tire pressure.
From the first coffee before race day warm-up to the post-ride debate about whether you should’ve gone half a PSI lower, the Challenge Tire Pressure Mug is made for riders, mechanics, and anyone who’s ever blamed a bad line on their setup.
Made from white ceramic, this 11 fl oz (approx. 325 ml) mug features our black-and-red design and is both dishwasher-safe and microwave-safe.
