YunSCM 2-Pack 18 Inch Bike Inner Tubes, Schrader Valve

Quick Summary

The YunSCM 2-pack bike inner tubes are 18 inch tubes for bicycles with an AV Schrader valve. The stated size range is 18 x 1.75 to 2.25, with ETRTO 45/57-355 also listed for the same tubes.

This pack is for buyers who need two replacement inner tubes and want to match the wheel size, tyre width range and valve type before choosing an offer.

Key Details

What to Compare Before Buying

• Wheel size: These tubes are for 18 inch wheels, so compare the tyre and rim markings on your bike.
• Tyre width range: The stated fit is 18 x 1.75 to 2.25. Check that your tyre sits within that range.
• Valve type: The tubes use a Schrader valve. Make sure your rim and pump setup match that valve type.
• Pack quantity: This is a 2-pack, which suits buyers replacing more than one tube or keeping a spare.

Compatibility, Size and Fit

The stated fit covers 18 x 1.75, 18 x 1.90, 18 x 1.95, 18 x 2.0, 18 x 2.10, 18 x 2.125 and 18 x 2.25 tyres. The pack is intended for bikes using the listed 18 inch size range and a Schrader valve.

Because the valve length is stated differently in the available product text, confirm the length you need before ordering.

Before You Decide

Check the 18 inch size, the 1.75 to 2.25 tyre width range and the Schrader valve type against your wheel before choosing an offer. Also confirm the valve length you need, as the product text gives two different figures.
