Silca Latex Tube : 700x24-30mm PLUS 40mm Valve Extender w/ SpeedShield

Season:2018

Brand:Silca

Code:SIAMAC002ASY0200

Latex inner tubes have traditionally been confined to use in tubular tyres, where they are largely responsible for both the puncture resistance and ride quality of the finest tubular tyres. Now, SILCA has partnered with Vittoria, to create the highest quality, lowest rolling resistance, finest riding inner tube, sized for modern clincher tyre setups. 

Compared to standard bicycle inner tubes made of butyl rubber, Latex is significantly more elastic (10x greater elongation compared to 2-3x), but more importantly, Latex Rubber has a 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.

Ultimately this translates to a 2-5 Watt saving - per tyre - versus tubes made of other materials, when measured at 30mph. In addition, Latex tubes are harder to pinch-flat and offer superior suppleness and road feel, especially when combined with supple, low rolling resistance tclincher or open-tubular tyres.

This new latex tube has been sized to fit tyes 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.

The Latex tube and SpeedShield kit partners Silca's rubber SpeedShield covers and 40mm valve extenders to reduce damage to your rims while offering aerodynamic gains
