Depending on your riding style, you may prefer a fender over a brake, especially if you're doing a lot of manuals or fakies. Trynyty's 2nd generation of the Stingray fender does the trick, and works better than most. Made of lightweight, yet durable aluminum, the Stingray fender looks great and is really light due to the machined cut outs. The Trynyty Stingray fender is wide enough to fit most decks and features a long machined slot, rather than bolt holes, so it fits most decks. There were scooter brakes and then there were fenders. So, which should you buy? Easy, if you want to be able to stop, pick up a brake, which you can actually press down on with your rear foot to stop your whip. If you don't want that rear brake to inadvertently stop your wheel when your foot hits it on a big landing, you want a fender. Please note that a fender does not function as a brake and will not stop you. In other words, you're going to wear out a lot of shoes. The Stingray V2 fender is a aluminum fender that works with the following wheel diameters: 100mm,110mm,115mm,120mm and the following wheel widths: 24mm,26mm,28mm,30mm. Should you purchase metal or plastic brakes? It depends. If you are looking for the lightest possible setup - go nylon or plastic. If you want a durable brake that's going to last a long time, pick up a steel brake.
