Cámara de bicicleta FISCHER válvula Sclaverand (Presta) 28 pulgadas / 71,10–71,12 cm ETRTO

FISCHER inner tube with Sclaverand (Presta) valve for 28" wheels, specified for 71.10–71.12 cm ETRTO sizing. This replacement tube is made to fit bicycle tyres and rims that match the given ETRTO dimension range and is intended for use on road and hybrid bikes where a 28" (700C) tube with a Presta valve is required. The Presta valve allows for a secure seal and compatibility with presta-capable pumps and standard presta adapters.

Advantages

The tube offers a precise fit for tyres sized to 71.10–71.12 cm ETRTO, reducing the risk of pinching or improper seating during installation. The Sclaverand (Presta) valve enables reliable inflation control and a slim valve profile suitable for narrow rims. As a manufacturer-supplied spare, it provides a simple and direct replacement option for puncture repair or scheduled maintenance.

Suitable for

• Road bicycles with 28" / 700C wheels that accept Presta valves
• Hybrid bikes using tyres matching 71.10–71.12 cm ETRTO
• On-the-go tube replacement and workshop puncture repairs

Key specifications

• Valve type: Sclaverand (Presta)
• Wheel size compatibility: 28" (700C)
• ETRTO sizing: 71.10–71.12 cm
• Application: bicycle inner tube for tyre replacement

How to use

Remove the wheel from the bicycle and deflate the damaged tube fully before unseating the tyre bead. Inspect the tyre and rim strip for embedded debris or damage, then insert the FISCHER inner tube partially inflated to reduce the chance of pinching. Seat the tyre bead evenly around the rim, inflate to the tyre manufacturer's recommended pressure using a Presta-compatible pump or adapter, and re-fit the wheel to the bicycle, checking alignment and brake clearance. Ensure the valve nut (if present) is secured and the valve core is tightened after inflation.

Recommendations

Check the tyre sidewall for the exact ETRTO number to confirm compatibility before purchase. Use a properly sized tyre lever and avoid sharp tools to prevent tube damage during installation. Carry a spare tube and a small pump or CO2 inflator compatible with Presta valves for roadside repairs.
