GPS is super accurate and just makes everything easier. No wires, no magnets, no settings for different wheel sizes, no problem switching between bikes. The Cateye Stealth 10 GPS cycling computer is a great value on a GPS computer that has full-time backlight, upload capability, and delivers all the easy, no-hassle function of more expensive units at a fraction of the price. Weather is no issue either since the Stealth 10 is waterproof up to 10 meters. Just pop it on any bike, wait a second for it to find the signal, and head out on your merry way.
