Bicycle Inner Tube 29" Gel Filled Thick Valve 1.90/2.35

Compatible inner tube for 29 inch bicycle tires

Widths between 1.90 and 2.35 are suitable.

The thick valve SV48 mm, known as the engine valve, was used.

The gel inside the tire prevents the air from descending by filling a few small punctures (such as thistles, etc.) around the hole. Thus, the user can continue using the product without feeling a few small pops.

If the puncture is large, the gel may not be able to fill the hole.
