Rear mudguard TOPEAK TETRAFENDER M2 for 26"–29" wheels, model 2022, rear fender for bicycles

TOPEAK TETRAFENDER M2 rear mudguard (model 2022) is a compact, adjustable rear fender designed for bicycles with 26" to 29" wheels. It provides splash and debris protection for the rider and drivetrain in wet or muddy conditions, mounting to the seatpost area and extending coverage over the rear wheel. The fender aims to reduce water and dirt spray while remaining lightweight and easy to fit on a variety of frames.

Advantages

The TETRAFENDER M2 offers broad compatibility across wheel sizes and a streamlined profile that minimizes added bulk. Its adjustable mounting system and flexible blade allow for a close fit to the tyre and easy removal or repositioning. Constructed from durable, weather-resistant materials, the mudguard resists cracking and deformation under normal riding conditions and is suitable for repeated installation and transport.

Suitable for

• Urban commuting on wet or slushy roads
• Bikepacking and touring where light splash protection is required
• Gravel and light off-road rides to reduce rear splash
• Everyday cycling where a simple, removable rear fender is preferred

Key specifications

• Wheel size compatibility: fits 26"–29" wheels
• Position: rear (seatpost-mounted style)
• Material: impact-resistant, weatherproof polymer
• Adjustable length and angle for customized coverage
• Lightweight design for minimal added weight

How to use

Attach the TETRAFENDER M2 to the bicycle by securing its clamp or mounting bracket around the seatpost, then adjust the blade length and angle so the fender sits close to the tyre without touching it. Ensure fasteners are tightened to prevent movement during rides. For removal, loosen the clamp and slide the fender off the seatpost; for transport or storage, collapse or detach components as designed. Periodically check the mounting and blade condition after rides to maintain effective protection.

Usage recommendations

Regularly inspect the mounting hardware and blade for wear or damage, especially after rough terrain rides. Keep the fender clear of accumulated mud and debris to preserve airflow and prevent tyre contact. When fitting to unusual seatpost shapes or with seatpost-mounted accessories, verify clearances and secure attachment before riding.
