The original wide saddle guard, suitable for fatbikes or just a wider load. 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 fatbike mudguard, at just 45g. 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. See image. Easy to clean as it's flexible and opens flat. Simply wipe it and you're done.
