The original MTB saddle guard with an improved design: thicker, stronger and reprofiled for a better fit.

  • Prevents 'soggy arse syndrome'.
  • Fitted as close as possible to back face for optimum muck catching.
  • Prevents the top of your seat post from getting clogged up.
  • Discrete but very effective.
  • Possibly the lightest MTB rear mudguard, at just 30g.
  • No need for separate fasteners, making it easy to fit and take off.
  • Compatible with all standard double steel rail saddles, so long as they don't have any daft bits hanging off the rear.
  • Easy to clean as it's flexible and opens flat. Simply wipe it and you're done.
