Specialized Tubes|Mountain Mullet 27.5″/29″ TPU Inner Tube (Presta) (2.0 – 2.6″) (50mm)

Specialized Mountain Mullet 27.5″/29″ TPU Inner Tube Description:

The Specialized Mountain Mullet 27.5″/29″ TPU Inner Tube provides a very simple, lightweight, and space saving solution to carrying a spare tube when riding a mixed wheel-size bicycle. Made out of TPU, this tube is much lighter than a butyl rubber tube and much more puncture resistant. Perhaps the most unique thing about this tube is that it will easily fit within a 27.5″ tire and safely will expand to fill a 29″ wheel, plus it will take up about half the space that a normal tube would so there is more room within the on-bike storage or pocket for other tools, spare parts, and gear. Finally, the Specialized TPU Inner Tube is equipped with an aluminum alloy valve stem that is very durable and cut resistant, plus it is equipped with a removable core that allows damaged valve cores to easily be replaced.
