Maxxis Welter Weight 內胎 29 X 2.0/3.0 法式 FV 48mm

I was pleasantly surprised by the 0.80 mm wall thickness—it feels much sturdier than the cheaper tubes I’ve used before. The 48mm Presta valve fits perfectly in my deep rims without needing an extender, and the removable core makes adjusting pressure a breeze.

The 0.80 mm wall thickness gives me peace of mind on my rocky local trails; I've already hit a few sharp edges without a flat. Installation was a breeze with the removable valve core too.

The removable valve core is handy for adding sealant, but I wish the valve stem were a bit longer—it barely pokes through my deep rim. It works fine for standard setups, though.
