Fincci Pack Inner Tubes 700c x 35c x 38c with 48mm Schrader-Presta Valve - 700c Bike Tube for Gravel, Urban, Road,Touring, Hybrid, Bicycles, E Bikes -($17.91Value)

Description

Road bike tubes for a 700c bike tube setup on ISO 622 wheels, matching ETRTO 35–38 / 622 for wide tires. 2-pack set mounts on clincher rims for front and rear replacement during routine maintenance. Bike tubes made from butyl rubber use a presta valve core with 0.96 mm wall thickness. The tube expands evenly inside wide casings and uses a molded, vulcanized seam, with no reinforced protection layer. Inner tubes for bike tires run at 40–80 PSI depending on tire limits and inflation steps. Pressure follows the mounted tire specification and supports mixed-surface riding on 700c gravel tires when installed within the supported width range. A 700c inner tube with 48 mm Presta valve fits standard rim valve holes and standard rim depth, not deep rims. Fixed core stays aligned while pumping, and included plastic caps protect the valve during transport. The 40-622 700x38c bike tube range covers 35c–38c tire widths for gravel and touring use. Each tube weighs ~170 g (set ~340 g) and folds flat for pack storage or carrying as spares. This bicycle inner tube set is designed for wide 700c wheel systems used in commuting, touring, and mixed-surface riding. It supports routine replacement and aligns with common formats like 700cc bike tube and 700c tube in everyday maintenance contexts. During riding, the tube maintains a stable round shape inside the casing so the tire rolls consistently under load. The construction uses butyl rubber as the core material and is intended for predictable use rather than extreme performance framing. The tubes are commonly used with cyclocross tires and wide gravel setups where mixed pavement and compact gravel are expected. Compatibility aligns with tire formats such as 700x38c bike tire, 700x40c bike tube, and 700c bike tire used on endurance-oriented bicycles. Installation follows standard clincher mounting steps and works with common road bike accessories during routine ownership. The set functions as a 28 inch bike tube option and a standard bicycle tire tube; tubolito 700c road and cámara bicicleta carretera 700c are not implied.
