Inner Tubes

Inner tubes are the cheapest item in the catalogue and the one that generates the most repeat purchases, which makes them a useful loss-leader for a direct-to-consumer brand.
Our 700C tubes cover 28–40 mm tyres, with Presta valves in 48, 60 and 80 mm lengths. Butyl construction, with a wall thickness that suits everyday riding rather than weight-weenie builds.
Get the valve length right: a 48 mm valve will not reach through a 50 mm deep carbon rim. Deep-section wheels need 60–80 mm, and this is the single most common tube mismatch.
Tubes are usually packed with complete bikes and shipped as spares — see container loading for how small parts affect packing.
