I have had a Planet bike Protege 9.0 and have had problems with the sensor going bad so I switched to Cateye Enduro 8 and now I have gone through 2 sensors since last season. They seem to work on my road bikes a while but does anyone else have this problem of cyclocomputers that stop working or picking up a reading? Please let me know if there is a beter XC trail computer and I have not tried wireless thinking it would be more trouble
