Is the Continental Light Tube Worth It for Road Performance?

The Continental Light Tube earns its name through a thinner wall construction that reduces both weight and rolling resistance compared to a standard inner tube. By minimizing the thickness of the butyl rubber casing, Continental decreases the energy lost to internal flex with each wheel rotation, delivering a real difference in road speed for a very small investment. For riders running high-performance clinchers like the Grand Prix 5000, this is one of the most overlooked and cost-effective upgrades in any road setup.

The 700x20-25mm size covers the most popular road tire dimensions, and the 80mm Presta valve is specifically suited for deep-section aero rims where standard valve lengths fall short. Continental maintains tight quality tolerances on the Light tube's construction to ensure reliable air retention alongside the reduced weight, so you are not trading durability for speed in your training or race-day builds. Roll one up and stash it in your jersey pocket or saddle bag. It is genuinely the lightest and most compact spare you can carry.
