Fincci 700x35c / 38c / 40c / 42c / 45c / 48c Bike Inner Tube – 48mm Presta Valve 28c Inner Tube – Butyl Rubber – Fits Hybrid, Road & Gravel Bikes – Pack of 2

Pack & Sizing

Gravel bike tubes for a 700c bike tube setup on 622 wheels, matching ETRTO 35–48 / 622 for wide tires. 2-pack set mounts on clincher rims for front and rear replacement during routine maintenance.

Material & Construction

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. Each tube weighs 170g.

Pressure & Performance

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.

Valve Type

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.
