Product Information

Full details

The Mucky Nutz Gut Fender is an essential accessory for mountain bikers and gravel riders looking to keep their midriff, drivetrain, and shoes free from mud and trail debris. Weighing a mere 30g, this ultralight down tube protector offers a discreet solution for those who want protection without the bulk of traditional mudguards, though it does not provide the full vertical coverage of a frame-mounted rear fender.

Extended Product Information

FAQs

Will this fit a carbon fiber frame?

Yes, the rubber contact points are designed to protect frame finishes, including carbon fiber.

Can I use this with a bottle cage?

Depending on your frame's design, it can often be installed alongside a bottle cage by sharing the same mounting bosses.

Does it require special tools to install?

No, it uses zip ties for universal fitment, though a pair of snips for the ties is helpful.

How do I clean the fender?

A simple rinse with water and a mild soap is sufficient after muddy rides.

Can it be installed on an e-bike?

Yes, provided the down tube geometry allows for the mounting of the fender and it does not obstruct the battery casing.

Troubleshooting

Fender is sliding down the frame

Ensure the zip ties are pulled tight and the rubber contact pads are clean and free of debris.

Fender vibrates or makes noise

Check that all contact points are touching the frame and that no debris is trapped between the plastic and the bike.

Difficulty with cable routing

Reposition the fender slightly higher or lower on the down tube to clear external shift or brake housings.

Pros and Cons

Pros

  • Extremely lightweight at 30g
  • Easy to install and remove
  • Prevents mud and grit from hitting the drivetrain
  • Discreet, low-profile aesthetic
  • Rubber contacts prevent frame scratches and movement

Cons

  • Does not protect the rider's upper torso
  • May require regular cleaning to maintain efficiency
  • Limited coverage compared to full-length mudguards

Setup, Compatibility & Care

Installation is straightforward and can be completed in minutes. Depending on your frame's design, use the provided zip ties to secure the guard to the down tube, ensuring the rubber contact points are flush against the frame to eliminate rattling. If your frame features bottle cage bosses, you can align the fender to use these for a cleaner, bolt-on attachment. To care for your fender, simply rinse it with water after muddy rides; the durable material is resistant to mud buildup and can be wiped clean with a soft cloth. Avoid using harsh chemical solvents that could degrade the rubber contact pads.
