Continental 700x20–25c Race Inner Tubes, Pack of 4 — 60mm Presta, Butyl

These inner tubes are made from high-quality butyl rubber and are manufactured with mold-cured vulcanization to maintain consistent roundness and dependable fit in 700x20–25c tires. Each tube undergoes a 100% inspection process to meet Continental’s quality standards. Packaged in original Continental retail boxes (not bulk), the set of four is ideal for riders who want spare tubes that match their race or training wheels.

How do these tubes affect ride feel and handling?

The seamless construction and vulcanized molding help the tube keep a uniform shape, which minimizes pressure irregularities and improves tire seating. A consistently round tube supports stable handling at a range of inflation pressures common to road cycling.

• Seamless butyl construction reduces uneven bulging under load
• Mold-cured vulcanization improves roundness and balance
• 60mm Presta valve provides easy pump access with deep rims
• Sizes matched for 700x20–25c tire profiles

Will these tubes fit my wheel and rim depth?

The tubes are sized for 28"/700c wheels and fit tires with widths from 20mm to 25mm. The 60mm Presta valve length is intended for rims with moderate to deep profiles; it gives enough valve shaft exposed for convenient inflation without extensions in most road wheel setups.

• Compatible with 700c rims and tires 20–25mm wide
• 60mm valve suits deeper rims and gives easy pump access
• Works with both clincher and standard road tire assemblies

How durable and serviceable are these inner tubes?

Constructed from butyl rubber, these tubes balance air retention and puncture resistance typical of standard road tubes. Every tube is inspected during production, which reduces the chance of manufacturing defects and increases reliability for training and event use.

• Butyl material offers good air-holding properties and longevity
• 100% quality inspection reduces factory faults
• Sold in Continental retail boxes—each tube individually packaged
• Pack of four gives spares for training or group rides

How should I carry and replace these tubes on the road?

Carry one or two spare tubes, tire levers, and a pump or CO2 inflator for quick roadside repairs. Replacing a tube requires removing the wheel, taking out the tire bead, swapping the tube, and inflating to your preferred pressure while checking bead seating and valve alignment.

• Pack individual tubes in a saddle or jersey pocket for minimal weight
• Use tire levers to avoid pinching the new tube during installation
• Check valve stem straightness before fully inflating to prevent leaks
• Inflate briefly, confirm bead seating, then top up to target pressure

Who is this for? These Continental Race inner tubes are aimed at road cyclists—club riders, commuters who use narrow road tires, and anyone needing reliable spares for training or events. If you run 700x20–25c tires and want a well-made butyl tube with a longer (60mm) Presta valve, this pack of four provides a ready supply of OEM-quality replacements in retail packaging.
