Quick Summary
This 2-pack of bike inner tubes is sized for 700×38/45C tires and uses a Schrader valve with a 35 mm stem. It is a straightforward replacement option for riders who need tubes that match the stated tire size and valve type.
The tubes are described as heavy duty, but the main buying checks are still the tire size, valve type, and stem length. Confirm those details against your wheel and tire setup before choosing an offer.
Key Details

|---|---|
| Pack quantity | 2 tubes, which matters if you want a spare on hand. |

What to Compare Before Buying
- Tire size: Match the stated 700×38/45C size to your tire size before ordering.
- Valve type: Schrader valves are not the same as Presta valves, so confirm the valve type you need.
- Valve stem length: The 35 mm stem should suit your wheel and rim setup only if that length is appropriate.
- Pack quantity: This set includes 2 tubes, which is useful if you want to replace more than one tube or keep a spare.
Before You Decide
Check the 700×38/45C size, Schrader valve type, and 35 mm stem length before choosing an offer. Confirm that a 2-pack matches the number of tubes you want to replace or keep in reserve.
