Have two of these on different bikes and they haven't let me down yet.The bracket can only sit on the stem so short fatty ones might be a problem.The computer tells you all you need to know and the are figures clear and large.The cable is extra thick and strong to increase life.These are the last models sigma will do so get one before they go.
This computer & sensors mount on your bike using rubber bands - the computer bracket sits on the stem which may be a pain to get the thing in and out of the holder if you have a short stem with a large handlebar clamp. I ended up mounting the sensor on the v brake boss using the brake line as a guide/mount down to the forks - cable isn't long enough to reach all the way down my 100mm forks but it looks alot tidier. It is v easy to use being auto start and gives you max speed, distance travelled, time taken, av speed - but not cadence. There is a wireless upgrade available which i would consider if you have room on yr handlebars.
