The Cateye Strada wireless computer has been the gold standard in cycling computers. The new Strada Slim is a "slimmed down" version of the Strada wireless. The newly designed circuitry and increased efficiency allows for a smaller battery, so the computer can be thinner and lighter. The smaller packages still boasts the same great cycling features and functions with a larger screen and the ability to customize your display by showing only the functions you select.
