Silca Latex Inner Tube 700×24-30mm with 70mm Extender and Speed Shield

Silca Latex Inner Tube 700×24-30mm with 70mm Extender and Speed Shield Silca joined forces with industry experts Vittoria to create a Latex Inner Tube that boasts a supple and superior road feel coupled with low rolling resistance. Sized for modern clincher tyre setups marked 22-30mm (or 22-28mm on a wide rim); the 42mm valve can be extended by 70mm using the included valve extender. With impressive watt-saving characteristics; Silca claims the latex inner tube can save as much as 2-5 watts per tyre compared with traditional butyl tubes when riding at 30mph. The natural stretchiness of the material also makes this latex inner tube harder to pinch-flat than butyl. The included SpeedShield protects the rim from valve nut damage while eliminating valve stem rattle and further improving aerodynamics. Please note; Silca strongly recommends using two wraps of tubeless rim tape when using latex inner tubes. Tubeless tapes make installing tyres easier; making the tube less likely to move around and less likely to pinch the tube during installation.
