The posterior is right up there when it comes to bits you want to keep dry. Yet here in London in particular there's a certain type of cyclist that doesn't want to burden their bike with a proper mudguard. Enter the Ass Saver. It's a tiny little bit of folding plastic that slots in underneath your saddle. When it's dry, it hides away underneath; when it's wet, it unfolds to provide a wedge-shaped bit of bum protection from spray arcing from the top of your back wheel.
There's still a bit of life in our wet and windy spring yet, so these Full Windsor Quickfix rear mudguards might be a life-saver.
Full Windsor is a London-based bicycle accessories design company, named after its founder, Mark Windsor. From the name, you might think they actually make ties, but in fact these are mudguards with a clear resemblance to a necktie. Made from durable plastic and available in a range of colours, they're easy to fix and work very well.
