The Sunlite 27.5in Thorn Resistant Presta Tube fits 27.5 x 2.10–2.35 mountain bike tires. Its thick 4.3mm thorn-resistant construction adds extra protection for trail riding, commuting, and rougher terrain where flats are more likely.
Both versions use threaded Presta valves with removable cores. Choose the 32mm or 48mm valve length based on your rim depth and valve access needs.
