Challenge 700c Seamless Latex Inner Tube Description:

The Challenge 700c Seamless Latex Inner Tube offers improvements to the ride and performance for anyone using tubes within the tires of their road, all-road, and gravel bike. Seamless latex construction eliminates bumps, provides a smoother ride, reduces rolling resistance, and will reduce rotating weight when compared to a butyl rubber tube, making these tubes an inexpensive way to improve the performance of the bike. Additionally, the smooth aluminum valve stem has a removable valve core so valve extenders can be attached, allowing the Challenge 700c Seamless Latex Inner Tube to be installed within very deep wheels.

Features:

• Seamless, "one-piece" latex road inner tube does not have the pucker or bump commonly found on other tubes resulting in a smoother ride
• Latex material can be formed into a thinner walled tube for a lighter, more flexible tube that improves comfort and reduces rolling resistance
• Smooth aluminum valve stem with a removable valve core enables the ability to attach valve extensions so these tubes can be used with wheels with a very deep profile
