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.
