Silca Ultimate TPU Tubes (700c) are built to be the perfect spare, a premium upgrade to butyl tubes, or a serious alternative to tubeless setups. Made from Thermoplastic Polyurethane (TPU) for strength, flexibility, and air retention, they are built to be the most reliable lightweight compact tubes available.
A patented mechanical valve connection, a threaded aluminum valve with locking nut, and precise material construction solve the common problems found in most other TPU tubes. The result is a tube you can ride daily for dependable, lightweight performance, or keep as the ultimate compact spare that delivers long service life when you need it most.

I like that this tube has a removable valve core to add an extender but I believe the tube is too thin to support the metal valve. Others like the Pirelli are thicker but do not have a metal valve. I believe it adds too much stress to the tube so beware if you plan to add an extender to this tube.
I do prefer the pirelli but their valve lengths don't fit all of my wheels.
