29" BICYCLE INNER TUBE COMPATIBILITY — Designed to fit 29 x 2.125, 29 x 2.20, 29 x 2.30, and 29 x 2.40 (40/62-622) tire sizes. This set of two tubes, equipped with a durable 37 mm Schrader (AV37) valve, ensures excellent flexibility and a perfect fit for mountain, cruiser, and city bikes.
STRONG AIR-TIGHT BUILD – Crafted from high-elasticity, mould-cured butyl rubber that seals air effectively and resists pressure loss. The reinforced Schrader AV valve with rubber base provides a secure seal and smooth inflation. Thick walls maintain steady pressure, reduce refills, and keep rides stable and safe.
DURABLE & PUNCTURE-RESISTANT DESIGN – The thick butyl rubber body withstands friction, heat, and road wear better than standard tubes. Built to handle long rides, daily commutes, and rough terrain, it extends tube lifespan and reduces maintenance frequency.
EXCELLENT SHOCK ABSORPTION – The flexible butyl rubber construction absorbs vibration and road impact, reducing bumps for a smoother, more comfortable ride. The reinforced valve base adds durability and helps prevent leaks for consistent performance.
COMPLETE 29" BIKE TUBE KIT – Compatible with mountain, cruiser, city, and electric bikes. Each set includes two premium butyl rubber inner tubes and two tire levers for quick, easy replacement. Fits 29x2.125–2.40 tires perfectly for fast installation and reliable everyday use.
