*How to choose the right inner tube size?
Check the specification markings on the original outer tire sidewall, such as 26*1.95 or 700x32C. Take a photo or inform me, and I will assist in selecting an inner tube based on your outer tire size. If the outer tire is marked as 700x32C, you can choose a 700x32C-47C inner tube (due to the elasticity of inner tubes, sizes within the 700x32C-47C range are compatible).

*How to select valve stem size?
We offer three lengths of Presta valve stems: 45mm, 65mm, and 85mm.
Select the valve stem based on your rim's valve hole position. The valve stem length must match your rim's thickness. For easier inflation, we generally recommend choosing a valve stem 2cm longer than the rim's valve hole position.

Note:
1. The real color of the item may be slightly different from the pictures shown on website caused by many factors such as brightness of your monitor and light brightness.
2. Please allow slight manual measurement deviation for the data.

Before Installation:
When the outer tire is not installed, slightly inflate the inner tube to no more than 5 psi to help it retain its shape.
Avoid overinflation, which can cause irreversible damage and result in irreparable swelling! — Maintain a low air pressure to prevent damage during installation.

Seam Display:
The seam is slightly thicker than the rest of the fabric, so the excess material serves as protection and is intended for normal use.

1. Do not overinflate this inner tube before installing it inside the outer tire, as this will cause irreversible damage!
2. Inflate it 2–3 times while it is empty, keeping the pressure below 2 PSI. Exceeding 2 PSI will cause irreparable swelling.
3. When installing, first inflate to 0.5 PSI. While inflating, ensure the inner tube is pressed against the inner wall of the tire, then press and adjust the inner tube into place.
