There are a range of factors that can affect your cycling speed. Obviously fitness is one of them; however, weather conditions and the varying gradients of the road play a huge part too. The most advanced way of measuring how these factors affect your performance speed is with the aerodynamic Wireless Polar CS speed sensor.
Polar CS Speed Sensor Features:
Measures your current, average and maximum speeds
Track your average speed to see your progress and performance improve
Light yet tough, and easy to attach
Buy Polar CS Speed Sensor from Chain Reaction Cycles, the worlds largest online bicycle store.
Rated 5 out of 5 by Anonymous Do not go for GPS
Advice from one reviewer was to go for a GPS system instead of a speed sensor. this is not good advice. GPS systems 'lag' in terms of speed. They also cannot tell when you are 'really' stationary, so moving averages etc.. get messed up. There is no substitute for a real speed sensor.

Rated 4 out of 5 by Anonymous Full Second Bike Kit
I Bought this for my XC bike as i already had a polar CS100 for my road bike for 4 years now. The package includes the sensor, cable ties and a computer mount to get your second bike set up. There's no need to buy the overpriced computer twist mount in addition to this.
I wish the sensor/computer had more range so i could locate the sensor closer to the axle, it's a bit ugly looking sitting so high up on my forks and having to twist so much to pick up a signal from the spoke magnet. However, once setup and aesthetics ignored, it's a no brainer to use and now i can data log on my XC bike.
If you have the money, go for a GPS system, this technology is dated. But if you just want to put your polar on a 2nd bike, this does the trick nicely.
