Bicycle Tube

KB Bicycles LLP offers butyl rubber bicycle inner tubes in sizes spanning 26 inch, 27.5 inch, 29 inch, and 700c diameters, with widths from 18 mm up to 45 mm depending on the variant. Valve types include Schrader (AV48), Presta (FV48), and removable-core Presta in 60 mm and 80 mm lengths (RV60, RV80), giving coverage for rim depths from shallow road rims to deeper disc-brake wheels. The HSN code 4013 classifies these as rubber inner tubes for tyres, which governs import duty and regulatory filing. Each tube is specified against a suggested maximum operating pressure and is intended for clincher tyre setups on standard bicycle rims.

Butyl rubber remains the standard material for bicycle inner tubes due to its low gas permeability compared to natural rubber, typically holding inflation pressure three to five times longer. The tube construction involves extruded butyl compound with mould-cured seams, and valve stems are bonded with brass or alloy bases. Wall thickness for general-purpose butyl tubes typically ranges from 0.87 mm to 1.05 mm, with thicker variants available for puncture resistance. The 700x18/25 FV48 size targets high-pressure road applications, while 29x1.75/2.35 AV48 suits mountain bike pressures; buyers should confirm the exact butyl percentage and any added puncture protection layers, as these are not stated in the source data.

These tubes serve bicycle assemblers, aftermarket distributors, and retailers supplying road, mountain, hybrid, and commuter markets. The Mumbai location places KB Bicycles LLP near Jawaharlal Nehru Port Trust, India's largest container port, which can simplify export logistics. The listing shows FOB export pricing in USD but does not specify the loading port, Incoterm variant, or payment structure. Buyers should confirm whether pricing is FOB Mumbai or another point, minimum order quantities per size and valve configuration, and whether valve cores are replaceable or fixed on the non-removable models.

KB Bicycles LLP is registered in Lower Parel, Mumbai, Maharashtra, with a trust tier of harbor. The response rate and average response hours are both recorded as zero, meaning no engagement metrics are available and direct communication is essential before reliance. The supplier address places operations in central Mumbai, a commercial district rather than a manufacturing zone, so buyers should clarify whether the company holds inventory, acts as a trading house, or operates bonded warehousing near the port.

The product range is focused on bicycle inner tubes with defined size and valve configurations, suggesting specialisation in aftermarket replacement and OEM supply rather than broad bicycle assembly. No factory certification, ISO registration, or export history is stated in the profile, and these must not be invented. Buyers should verify whether KB Bicycles LLP manufactures tubes under its own tooling or sources from a butyl extrusion partner, as this affects quality consistency and the ability to customise packaging or branding.
