I have a non-biking Garmin GPS (Oregon) that I use for geocaching, but it's larger than I want to use on my bike, so I want a bike computer. Are the wireless ones the way to go, or the wired ones? I'd like to avoid "clunky" but I've never seen either one installed. I'd just like distance and speed, don't care about HR, cadence, etc. Any recommendations? Just trying to get started doing a little riding for fun, haven't even bought a bike yet but have researched them alot and waiting for the bike shop to get one in in my size. Thanks
