Continental Cross 28″ 700×32-47c Inner Tubes
The Continental Cross inner tubes feature seamless construction and mold-cured vulcanization to ensure uniform roundness. They are sized for 28″ wheels with a range of 32-47mm, offering compatibility for riders who run 700x42c tires. The valve type is a 42mm Presta valve, which provides good clearance for many rims and fenders. This option emphasizes reliable inflation stability and steady performance across a variety of 700c tires, including those near 42c width.
700C Heavy Duty Tubes for 700x35C–43C
This heavy-duty inner tube line covers 700x35C through 43C with AV48 Schrader valves. It’s designed for enhanced ductility and stronger bite into the rim. The tube’s coating emphasizes air retention and vibration dampening on rough roads, helping to maintain consistent pressure and ride quality over longer distances and variable pavement surfaces.
2 Pack 700×35-43c Road Tubes with Levers
These 2-pack inner tubes fit 700c road bikes from 35c to 43c and include two tire levers for convenient field repairs. The tubes use high-quality butyl rubber to improve air tightness and heat resistance. The set is designed for riders who value quick, on-the-go maintenance and reliable sealing under varied temperatures and riding conditions.
2-PCS Self-Sealing 700C Tubes RFV48mm
This pair features 48mm RFV Presta valve compatibility with a self-sealing system pre-installed. The self-sealing sealant is designed to automatically repair small punctures within seconds during normal riding. The thicker tube design increases overall durability, making it appropriate for riders who encounter thorny terrain or urban debris and want continued ride integrity without frequent flats.
2 PCS Heavy Duty Schrader Tubes 700×38-45C
These heavy-duty Schrader tubes are suitable for 38-45c tires, providing compatibility with 700c wheels across a broad width range. The walls are thicker for improved air retention and resilience against punctures or impacts. The set emphasizes reliable performance in mixed riding conditions, from pavement to light gravel, while maintaining strong sealing and consistent pressure.
Buying Guide
- Valve choice: Presta valves (short or long) suit many road rims with tighter clearances; Schrader valves are widely compatible with more rims and easier inflation with common pumps. For fender-equipped bikes, consider shorter Presta or Schrader variants depending on clearance.
- Tube width range: Ensure the tube’s size covers your tire width. For 700x42c tires, choose tubes labeled for 700×35-43c, 700×38-45c, or similar ranges to maximize compatibility and avoid pinch flats.
- Butyl rubber vs. self-sealing: Butyl tubes rely on air pressure to seal punctures; self-sealing tubes include sealant to quickly fix small holes. Self-sealing variants are beneficial for urban riders and those who encounter frequent small punctures.
- Durability and wall thickness: Thicker-walled tubes offer better puncture resistance and puncture repair confidence, at a slight weight cost. Consider your terrain and riding style when selecting a heavier tube.
- Repair accessories: Some sets include tire levers and patch kits, which can be worthwhile for maintenance on long rides. A compact kit helps with quick field repairs without extra gear.
- Compatibility with rims: Check your rim bed and valve hole size. Some rims require deeper valve holes for longer Presta valves or may fit Schrader valves with adapters. Always confirm valve length relative to rim depth.
- Air retention performance: Tubes with enhanced air tightness (thicker walls, proprietary blends) tend to lose air more slowly, reducing inflation frequency on long rides and tours.
- Temperature and usage: Some tubes perform better under heat or cold conditions. If you ride in variable climates, a reliable, heat-resistant tube helps maintain consistent pressure.
