Getting a new Orbea San Remo on the cycle to work scheme and going to get a cycle computer installed. Can anyone give me the adavantage of both these computers.
Cant afford a duel computer which does both. My aim to to loose weight and get fitter.

I go to work and back 7 mile each way every day and do about 40 miles on a saturday or sunday.
