Product Details

Includes 2 tubes - save 2-5 watts per wheel!

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 tire) 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 tires. This tube has been sized to fit tires measuring 24-30mm, which will equate to 23-28mm tires used on modern wider rims. Valve stem length is 42mm and will work in all modern disc wheels.
