Bike Tube With Long Stem

High-profile rims and disc brake frames are increasingly common, and normal valves are often too short, making air pumping difficult. This bike tube with long stem addresses that issue. Valve lengths are 60, 80, and 100 mm-longer than standard 48 mm valves. The 60 mm valve fits most deep rims, while 80 mm and 100 mm valves are ideal for very deep carbon rims. Sizes cover 700C road bikes and 26, 27.5, and 29-inch mountain bikes. The material is durable butyl rubber. Wall thickness varies by bike type: thinner for road bikes, thicker for mountain bikes. Air pressure ranges from 30 to 100 PSI, depending on the bike.

Our factory has 16 years of experience, and customer feedback inspired this product. The joint between the valve and the tube is reinforced, preventing leaks caused by the additional force required when pumping long stems. Monthly production capacity is 1 million units, with an MOQ of 10,000 pieces. Sizes and valve lengths can be mixed. OEM is supported. Free samples are available, and custom samples are ready in one week. Quality follows national standards, with full inspection before packing. Third-party inspections are welcome.

Warranty is 3 months. Payment terms are 30% in advance and 70% before shipment, accepting USD. We ship DDP to your warehouse. A common question is which valve length to choose: 60 mm works for most deep rims, while 80 mm and 100 mm are for very deep carbon wheels. Stock this bike tube with long stem to serve high-profile rim users and meet their needs effectively.
