Barbieri NXT Blob Road bike tube

BLOB the world's first TPU chamber with sealant.

Lightweight and puncture-proof. Openable valve with key cap supplied. Store folded chambers as packed. In this way, the sealant will keep for longer. 2) The sealant is subject to weight loss over time. We recommend adding 30 ml for RUN bikes, 50 ml for GRAVEL bikes, 80 ml for MTB bikes. 3) The presta valves can be opened with the special stopper provided. 4) The BLOB NXT BARBIERI chamber allows you to continue cycling even if you have punctures up to 3-4 mm. 5) Should the sealant fail to close the hole immediately, simply turn the wheel so that the sealant is distributed over the entire surface of the chamber and inflate quickly. 6) Once back in, we recommend locating the hole and closing it.
