Full details

The Polisport S-Mud Rear Mudguard is designed for road and MTB cyclists seeking a minimalist, lightweight solution to prevent splash and debris accumulation. It is ideal for riders who want quick-on, quick-off utility for fluctuating weather conditions, though its coverage is focused on rear-tire spray rather than full-frame protection.

FAQs

Does this fit oversized carbon saddle rails?

No, the S-Mud is designed specifically for standard 7mm metal saddle rails.

Can I use this with a dropper post?

Yes, because it mounts to the saddle rails and not the seatpost, it is fully compatible with dropper posts.

Is it suitable for 27.5-inch wheels?

Yes, the S-Mud is compatible with wheels ranging from 26 inches up to 29 inches.

How do I remove it for racing?

Simply release the quick-clip mechanism to detach the guard in seconds.

Will this protect my frame from mud?

No, this is a rear-facing mudguard designed to protect your back; it does not protect the frame or drivetrain from debris.

Troubleshooting

Mudguard vibrates or rattles during riding

Check the quick-clip tension and ensure the guard is securely snapped onto the saddle rails.

Mudguard touches the rear tire

Use the height adjustment point to rotate the guard further away from the tire surface.

Guard is loose on saddle rails

Ensure your saddle rails are standard 7mm diameter; if they are oversized, the clip may not seat correctly.

Pros and Cons

Pros

  • Extremely lightweight at only 74g
  • Mounts without needing any tools
  • Quick-clip system allows for rapid attachment or removal
  • Fits a wide range of wheel sizes (26 to 29 inches)
  • Clean, unobtrusive design

Cons

  • Not intended for full-frame mud or water protection
  • Limited coverage compared to full-length mudguards
  • Compatibility restricted to standard 7mm saddle rails

Setup, Compatibility & Care

To install the S-Mud, identify the 7mm saddle rails under your bike seat. Slide the quick-clip mounting bracket onto the rails and lock the mechanism into place. Use the 1-point adjustment feature to pivot the mudguard to the desired angle that provides the best arc over your rear tire. To care for your mudguard, simply wipe it down with a damp cloth after muddy rides. Avoid using harsh chemical solvents, as they may degrade the plastic finish. If the mudguard sits loose over time, ensure the clip remains clean of grit and debris to maintain a tight friction fit.
