Silca Latex Inner Tube - 700c (24-30 mm Measured Tyre Width) - Presta 42 mm + 40 mm Extender & Speed Shield

SILCA Latex Tube 24-30mm with 40mm valve core extension & Speed Shield.

SILCA has partnered with Vittoria to create the highest quality, lowest rolling resistance, finest riding inner tube, sized for modern clincher tire setups.

Compared to standard butyl rubber bicycle inner tubes, latex tubes are considerably more elastic (10x elongation compared to 2-3x). More importantly, Latex Rubber has significantly lower coefficient of damping which means that when latex rubber is stretched or flexed, it returns to shape faster and with less energy loss.

What does this mean for an inner tube? Latex inner tubes are generally 2-5 Watts (per tyre) more efficient at 30mph than tubes made of other materials. They are harder to pinch-flat and offer superior ride quality, especially when combined with supple, low rolling resistance tyres. This tube has been sized to fit tyres measuring 24-30mm, which will equate to 23-28mm tyres used on modern wider rims. Valve stem length is 42mm and will work in all modern disc wheels.

Specifications:

• Optimized for tires measuring: 24-30MM (Tyres marked 22-28mm when used on wide rims, or tires marked 24-30mm used on older narrow rims)
• Premium Latex
• 42mm Aluminum alloy valve, 10 grams lighter than Brass alloy valves and works in all modern disc wheels
• Removable Presta valve core
