FAQs

What is 'Soggy Arse Syndrome'?

'Soggy Arse Syndrome' is a common term used by cyclists to describe the discomfort and wetness experienced when mud and water spray from the rear wheel soak the rider's backside during wet conditions.

How does the Fat Butt Fender attach?

It attaches tool-free by sliding between the rails of most standard double-rail saddles and the seat post, then securing the fitting mechanism.

What is the maximum tire width this fender can accommodate?

The Fat Butt Fender is designed to work with fat bike tires up to 4.8 inches wide.

What material is the fender made from?

It is made from Mucky Nutz's signature high-performance material, which is 100% recycled plastic.

How much does the fender weigh?

The fender is ultra-lightweight, weighing approximately 35 grams.

What is the warranty period?

The Mucky Nutz Fat Butt Fender comes with a 1-year warranty.

Can this fender be used on a regular mountain bike?

While designed for fat bikes, it might fit some wider-tired non-fat bikes, but its optimal performance is with tires up to 4.8 inches.

Troubleshooting

Fender is loose or moves during ride.

Ensure the fender is securely fitted between the saddle rails and seat post. Tighten the fitting mechanism firmly. If slippage persists, check for debris on the saddle rails that may be preventing a snug fit.

Not enough spray protection.

Adjust the angle and position of the fender. Ensure it is positioned as close to the rear tire as possible without touching it. For more comprehensive protection, consider adding a secondary fender or mudguard.

Fender cracked or damaged.

The fender is made from durable plastic, but extreme impacts can cause damage. Contact Mucky Nutz customer support regarding warranty claims if the damage occurred under normal use within the warranty period.

Pros and Cons

Pros

  • Effectively prevents mud and water spray from reaching the rider's backside.
  • Lightweight and unobtrusive design.
  • Quick and easy tool-free installation.
  • Compatible with a wide range of fat bike tires and saddles.
  • Made from recycled materials.

Cons

  • Offers less coverage than traditional full-fender systems.
  • May not provide complete protection in extremely muddy or wet conditions.
  • Minimalist design might not appeal to all riders.
  • Effectiveness can vary slightly based on riding style and terrain.

Setup, Compatibility & Care

Setup: The Fat Butt Fender is designed for incredibly simple, tool-free installation. Simply slide the fender between the saddle rails and the seat post. Adjust its position for optimal coverage and then secure it by tightening the integrated fitting mechanism. The process takes only a few seconds.

Compatibility: This fender is compatible with all fat bikes featuring tire widths up to 4.8 inches. It fits most standard double-rail saddle designs. If you have an unusual saddle or very narrow tire setup, it's worth double-checking dimensions.

Care: Cleaning is straightforward. The fender can be wiped down with a damp cloth or hose it off with water. Avoid using harsh abrasive cleaners, as this could damage the material. Ensure it is dry before refitting if removed.
