Serfas replacement inner tubes are lightweight, durable, and affordable.

Grab the right tube for your 700C tire, just choose the valve length and tube size! When it comes to valve length: - 40mm valves are ideal for 10mm—30mm deep rims. - 60mm valves are ideal for 30mm—50mm deep rims. - 80mm valves are ideal for 60mm deep rims. And for tube size: - Check your tire's sidewall to determine its size—then choose the tube whose range includes it! For example: a 700Cx28 tire will work with the 700Cx25-32 or 700Cx28-32 tubes.
