📖 DETAILED DESCRIPTION

The Muc-Off No Puncture Hassle Road & Gravel 140ml is the ultimate choice for riders seeking maximum puncture protection combined with ultimate ease of use.

Engineered for Road and Gravel Pressures

While standard MTB sealants can struggle to seal holes when tire pressures exceed 3 or 4 Bar, the advanced Muc-Off Road & Gravel formula utilizes synthetic molecules and polymeric microparticles that cross-link instantly under strong air pressure, sealing cuts up to 7 mm on road and gravel tires.

Pouch Format: Mess-Free Top-Offs

The flexible 140 ml pouch features a specially contoured nozzle designed to fit snugly over a Presta valve stem (after removing the valve core). No more drips on the garage floor or frame: simply push the nozzle onto the valve stem and squeeze the pouch to inject the exact amount needed.

📐 RECOMMENDED DOSAGE PER WHEEL

A single 140 ml pouch provides enough sealant to set up or top off both wheels on a road or gravel bike:

• 700x23c – 700x28c (Road): 40 - 50 ml per wheel (1 pouch = ~3 wheels)

• 700x30c – 700x38c (All-Road / Gravel): 50 - 60 ml per wheel (1 pouch = ~2 wheels)

❓ FREQUENTLY ASKED QUESTIONS (FAQ)

Q: How do you apply the pouch to a Presta valve?

R: Simply unscrew and remove the Presta valve core using a valve core remover tool, fit the Muc-Off pouch nozzle over the valve stem, and squeeze the desired amount directly into the tire.

Q: Does the liquid dry out inside the tire?

R: The liquid remains active inside the tire for 3 to 6 months depending on climate conditions. We recommend checking sealant levels periodically before the riding season starts.
