About this item
  • 【Ultralight】 The new 700*18-32C road bike inner tube is 70% lighter than the old butyl rubber inner tube. This allows for a more responsive acceleration and a lighter ride, resulting in a significant speed boost. Weighing only 35g.
  • 【Compact & Practical】 This inner tube is 70% smaller than the standard size, making it compact and practical. It is convenient to carry and can be carried around easily. It does not take up a lot of space and is ideal for use as a spare inner tube on the go.
  • 【High Air Tightness】 By adjusting the valve, the tire employs more advanced technology, and the internal design of the valve stem has been modified to better align with the valve core, resulting in enhanced air tightness. Users can rest assured that there is no risk of air leakage or running out of air.
  • 【High-Quality Material】 ROCKBROS bicycle inner tubes are constructed using TPU and BASF's environmentally friendly recyclable materials. These inner tubes are strong and puncture-resistant, with a high rate of inner tube extension, which greatly improves their ability to resist scratches, abrasion and puncture.
  • 【Note】 It is important to note that the inner tube should not be inflated excessively without the outer tire being fitted, as this may cause irreversible damage to the inner tube. Additionally, it is advisable to inflate slightly to check for air leaks before mounting. When mounting, it is essential to inflate the inner tube slightly, ensuring that the inner tube is firmly pressed against the inner wall of the tire. Finally, the inner tube must be adjusted by pressing on it.

I wrote to Bigamart's customer support and they accompanied the process of reshipping the item until it finally arrived. I felt a genuine effort to solve the problem till it was finally solved.

The package was here in Australia from England in a few days — so quick! Something was missing and they refunded it straight away. Pretty happy with these guys.
