Continental Race 28in 700x20-25c Inner Tubes Pack of 5 - Presta 80mm

In this review of the Continental Race 28" 700x20-25c inner tubes, the bottom line is simple: these are a solid, no-frills replacement for riders running 700c tires in the 20-25mm range who want consistent manufacturing quality at a modest price. The reviewer found the tubes useful for everyday training rides and quick roadside fixes because of Continental's seamless, mold-cured construction and the longer 80mm Presta valve that makes pumping easier on deep-section rims. This is a practical five-tube pack for cyclists who value reliable roundness and standard butyl durability.

Key Features

• Seamless construction: The tubes use a mold-cured vulcanization process for uniform roundness, which helps reduce irregularities that can affect handling.
• 80mm Presta valve: The long Presta valve clears most deep-section rims, making inflation straightforward without additional extenders.
• Size compatibility: Sized for 28" 700 x 20-25mm tires so they fit common road and gravel setups within that width range.
• Butyl material: Constructed from durable butyl rubber for reliable air retention during long rides and daily use.
• Pack of 5: Supplying five tubes at once makes it convenient for regular riders, clubs, or as spares for a small workshop.

Who It's For

The Continental Race 28" tubes are aimed at road cyclists and commuters who use 700c tires in the 20-25mm width range and need dependable, readily available spares. They are a good pick for riders who value consistent manufacturing quality and prefer the familiar feel of butyl tubes over lighter but more delicate options.

These tubes are less suitable for racers chasing every gram or for those who require tubeless setups or specialty tubes made of latex. Riders who consistently puncture may prefer thicker puncture-resistant options, while tubeless converts will not find this the right product.

Frequently Asked Questions

Will these tubes fit 25c tires?
Yes. The tubes are rated for 700 x 20-25mm, so they will work well in 25c tires within that width range.

Do I need a valve extender for deep rims?
The 80mm Presta valve is long enough for many deep-section rims and often removes the need for an extender, but very deep rims may still need one.

Are these latex or butyl tubes?
These are butyl rubber tubes, chosen for air retention and durability rather than the lighter weight of latex.
