Lightweight TPU Inner Tube For 18 Inch Folding Bicycles Bmx

Lighten your ride with this thirty-four gram TPU inner tube built specifically for eighteen-inch folding bikes and BMX models. You will notice less rotational weight every time you roll over rough pavement. The flexible thermoplastic urethane resists cuts and seals tightly around three-fifty-five wheel tires sized one point two five to one point five inches. You gain faster pump sessions because the thin wall stretches easily under low pressure. This smart swap eliminates dead weight and keeps your small-wheel cruiser rolling smoothly.

Choose the valve profile that matches your fork hole for a seamless install. We strongly suggest pumping the tube by hand until it forms a gentle loop before tucking it into the casing. This habit prevents folds from triggering slow leaks later in the week. Track outdoor temperature shifts closely when you ride, since heat naturally expands air inside the chamber. Always drop pressure to one bar before leaving wheels in warm trunks to stop valve stems from deforming.

• Model Compatibility: Engineered for eighteen-inch folding bicycles and BMX frames using three-fifty-five rims.
• Core Construction: Ultra-thin thermoplastic urethane measures roughly thirty-four grams per tube.
• Valve Styles: Offered in forty-five millimeter and sixty-five millimeter Presta options, alongside a forty-five millimeter Schrader variant.

Package includes: One lightweight TPU inner tube matching your selected valve length.

Keep safety guidelines simple but firm. Do not blast this tube with a high-speed compressor or fill it heavily while it rests outside the tire shell. Hand pump it gently until the shape rounds out, then lock it near zero point five bars for initial seating. Maximum road pressure stays safely under five bars or seventy-two psi. Rapid sun exposure and hot blacktop quickly spike reading numbers, which can pop beads off narrow rims. Adjust your routine when summer temperatures climb past sixty degrees Celsius to protect valve integrity.
