Pure Cycles Standard Presta Valve Tubes

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.
