Main Features

Rating : - nice addition to the cycling computer world
I have a review on the forerunner 305, so this will be brief. the 305 for the bike does everything the fr 305 does except work with a foot pod.

the 305 for the bike is excellent at distance and HR measurements. you can take the unit off the bike and use it as a distance calculator for other activities, but you have to ensure the unit can see the sky at all time, which isn't easy unless it is strapped to your backpack (on the outside) however, since it is designed to be for the bike, I gave it 4 full stars for it.

the only thing really missing on this GPS unit is power meter aggregation.

that being said, the speed and cadence sensor is flimsy and breaks very easily. I have had 5, and evidently haven't learned my lesson on how to take care of it. I have had 3 on my road bike, and 2 on my tri bike. it is seemingly impossible to get both speed and cadence working simultaneously, and have broken the swing arm off 4 of 5 times. without having crashed.

all in all the unit gets 5 stars, it does anything you need except power for a biker in training. the speed/cadence sensor gets 1 star.
