TUBENOX has introduced a new standardized TPU inner tube sample program for bicycle brands, wholesalers and overseas importers. The program is designed to help customers simplify product selection, catalog development and market testing, with TPU inner tube options covering MTB, Road, Gravel and large-volume Gravel XL applications.
One Sample Program for Four Major Bike Categories
The TUBENOX sample range is organized around the most common wheel and tire combinations in today's bike market:
- 29×1.9–2.5 MTB – built for mountain bike use, with an emphasis on tear resistance, impact tolerance and durability;
- 700×18–32C Road – optimized for road bike applications, focusing on lightweight construction and high-pressure performance;
- 700×31–47C Gravel – suitable for gravel riding, with wider tire capacity and stronger dirt-road compatibility;
- 700×45–60C Gravel XL – designed for large-volume gravel setups, supporting more adventurous routes and higher tire volume.
We supply these TPU inner tubes with versatile valve choices to suit different market demands. Valves are offered in plastic, brass and aluminum alloy materials, covering three widely used stem lengths. This flexibility lets brands and wholesalers pick the right combination based on rim profile, weight requirements and cost planning.
Samples Help Reduce Bulk Order Risk
For B2B customers, a sample program is about more than just visual comparison. It is an efficient way to verify size compatibility, valve options, packaging behavior and product positioning before placing larger orders.
By grouping samples by application, TUBENOX makes it easier for customers to evaluate specifications across different bike segments. This is especially useful for brands preparing catalogs, distributors building product ranges or sellers preparing for Amazon and other online channels.
A Practical Tool for Sales, Catalogs and Customer Communication
Well-organized samples also improve internal and external communication. Sales teams can use them to explain size differences, product managers can validate SKU structure, and overseas buyers can confirm technical specifications before moving into mass production.
The TUBENOX sample program is particularly valuable for customers who want to test lightweight TPU tube performance across multiple bike categories without committing immediately to full production volumes.
