Yes, the Mudsling works well, especially if you ride a lot in wet weather. Not sure about SA but in Europe it is sold by Wunderlich. Denver should be able to comment. They also market an extender for the front mudguard which helps a lot to keep the splash down. Both items are very neat and unobtrusive but I don't think they are hardcore gravel/off road items. The Mudsling may cause problems in mud but for on-road use in wet weather, it is a clear winner.
