20" x 4.00-4.90 (Schrader) 48mm

Chao Yang Tube (Schrader Valve – 48mm)

Same reliability, just with a little more reach. This Chao Yang tube with a 48mm Schrader valve is perfect for rims that need extra valve length, making inflation easier and more accessible without fighting for clearance.

The longer 48mm valve is ideal for deeper rims or setups where a standard valve comes up short. Built from durable butyl rubber, it holds air consistently and handles everyday riding without hassle.

More reach. Same no-nonsense reliability.

Key Features:

• Schrader valve (standard car-style)

• 48mm valve length for deeper or wider rims

• Durable butyl rubber construction

• Strong, consistent air retention

• Easy to inflate and install

• Suitable for a wide range of bicycle tube sizes**
