Review: Nice - My bike part is very easy to install
Review: Good product. - Good quality product, great and speedy delivery. The only problem I had was that the colour of the wires were different to the original ones. I got past that by Cutting the plug off and using jelly crimps to reconnect in the correct order. Apart from that the censor is really good.

This does the job okay. I have bought 3 now for 2 different bikes. The first one wore through use but as it was so cheap I did not mind and chose to use again for the next bike build.
