Continental 700 x 20-25c Inner Tubes, Black, 80mm Presta Valve, Pack of 5

Continental Race 28 inner tubes are lightweight, reliable replacement tubes sized for 700 x 20–25c tires with an 80mm Presta valve, sold in a convenient pack of five.

These inner tubes are built for road cyclists who want a balance of low weight, dependable sealing, and easy valve access for deeper rims. Manufactured by Continental, a well-known name in cycling components, this five-pack gives you spares for training, group rides, or race-day contingency without compromising on materials or valve quality.

What tire sizes and valve length do these tubes fit?

The tubes are sized for 700c road wheels and suit tires from 20mm up to 25mm wide. Each tube features an 80mm long Presta valve, which is long enough to reach through most modern deep-section rims and makes inflation simple with floor pumps and track pumps.

• Compatible tire widths: 700 x 20c to 700 x 25c
• Valve: Presta (French) valve, 80mm length
• Removable valve core allows use of sealant or easy replacement

How do these tubes help on race days and training rides?

Because they’re lightweight and come in a multi-pack, these tubes are practical for riders who change flats frequently or want spares in a race kit. Continental’s construction balances puncture resistance with minimal weight so you can maintain ride performance without carrying multiple loose tubes.

• Pack of five provides multiple spares for long events or group rides
• Low-weight construction helps preserve bike handling and acceleration
• Removable core supports quick topping up or adding sealant

Are these tubes easy to install and maintain?

Installation follows standard inner tube procedures: partially inflate, fit into the tire, seat the bead, then fully inflate. The removable inner core simplifies maintenance — you can deflate completely, replace the core if needed, or add sealant without disassembling the valve.

• Presta valve compatible with common pumps and adapters
• Removable valve core reduces time to add sealant or replace the stem
• Standard size ensures easy fit for 700c rims within the specified width range

What should I consider when choosing these tubes for my wheelset?

Confirm your tire width is within 20–25mm and that an 80mm valve length reaches through your rim. If you have very deep rims or use tubeless-ready setups with inserts, verify clearance and compatibility. The pack is best for riders who prefer stocking several spares rather than single purchases.

• Measure tire width and rim depth before buying
• Choose a longer valve for deeper rims if needed
• Use the removable core feature if planning to add sealant later

Who this is for: Road cyclists, club riders, and race teams who need a dependable, lightweight set of spare inner tubes for 700 x 20–25c tires. This five-pack suits people who value easy valve access with an 80mm Presta stem, want the convenience of multiple spares on hand, and prefer a quality brand like Continental for consistent performance.
