Less than half the size of butyl in the Silca Ultimate TPU Tube

The Silca Ultimate TPU Tube for 700 x 24-43mm tires with a 50mm Presta valve packs down to less than half the size and weight of a butyl tube, so two spares fit where one used to. Silca built it around the weak spots of older TPU tubes, with a patented valve attachment that mechanically joins the valve to the tube and a welded joint to stop seam failures. The threaded aluminum valve helps the tube resist heat from an electric pump, and a valve nut keeps it secure and rattle free. Folded, it measures 38 x 77 x 24mm and weighs 45g.

Silca recommends this 50mm valve for rims under 40mm deep, and the version with a 70mm valve for rims 40 to 60mm deep. The valve core is removable, the tube works with rim and disc brakes, and each one comes with a patch and an alcohol wipe for a quick repair. Silca says it fits in its Mattone seat pack along with an Elettrico inflator, tire levers and a multitool. It is for riders on 700c or 29in tires from 24 to 43mm wide who want a smaller spare in the bag or a lighter tube in the tire.

FAQ

What valve length do I need for the Silca Ultimate TPU Tube?

Silca recommends the 50mm valve for rims under 40mm deep and the 70mm valve for rims 40 to 60mm deep. This listing is the 50mm valve for 24-43mm tires.

Can I put sealant in the Silca Ultimate TPU Tube?

No. Silca does not recommend filling the Ultimate TPU Tube with sealant or using it with sealant, because sealant inside a tube will likely not work properly. It can be used to fix a flat in a tire whose sealant has failed.

Can I inflate the Silca Ultimate TPU Tube with an electric pump?

Yes. Silca says to inflate in 10 to 15 PSI steps with an electric pump so heat does not damage the tube, and never to go past the tire maker's maximum pressure.

Does the Silca Ultimate TPU Tube work with rim brakes?

Yes. Silca tested it as thick enough for rim brakes in standard riding. On very long descents where the brakes stay on for 10 minutes or more, Silca says the tube could get too hot, so use caution.

Will the 24-43mm Silca Ultimate TPU Tube fit a slightly wider tire?

Silca says the TPU stretches enough for a slightly larger tire, and recommends staying within 2 to 3mm of the listed 24-43mm range. Silca advises against using it in narrower tires.

Is the Silca Ultimate TPU Tube covered by a warranty?

Yes. Silca covers it with a two-year limited warranty against manufacturer defects. The warranty does not cover punctures or failures from improper inflation.

Best For

Riders on 700c or 29in tires from 24 to 43mm wide with rims under 40mm deep who want a spare that takes less than half the room of a butyl tube, or who want to cut weight from a tubed setup.
