I was wondering what peoples thoughts are about the ErgoBrain. I hear a lot of complaining about "this" or "that" about different cycle computers, and the search function isn't working right now, so i figured i would find out peoples thoughts before i even consider buying this system.

Thanks

Well i am using one now. Troublesome to install, but the functions are nice. Given a toss up between this and the cateye double wireless, I would probably choose the cateye double wireless. One problem I encountered when I installed this is that one of the centre pivot shaft worked itself loose from the bushing holding the flat spring.

In reference to the picture it is number 7. What happens is that 7 mates to 15, and 15 is mated to spring 19 which is loaded. The mating sockets are quite shallow. The ergobrain sensor plug has 2 teeth that fits into the flat washer plate 18. When 7 came loose, the spring became unloaded and the washer plate was no longer in the correct position. The shifter is mechanically fine but the gear sensor no longer works. I figured this out after a day when I noticed the finger shift lever was in a slightly odd position. That was after removing and trying to disassemble the lever 3 times. After I found the problem, I removed the lever and partially disassembled it, used a large flat tip screwdriver to push the shaft down and spent a hell lot of time holding the thumb shift lever connected to spring 2 down while trying to get the bushing to fit. The spring was obstructing the bushing to it took a while to get it all to fit. After everything was in the right place I replace the flat spring 19 and preloaded it. I used a fair bit of grease and hope that will hold it all together.

The short of it is that now my shifter looks as well as works fine. However, the gear sensor is now a little wonky and only works halfway. It works for one or two of the gears at both ends, but not in the middle gears. Well I would settle that another time. Had enough of removing my bar tape and retaping it. One word of warning, the amber coloured washers included with the ergobrain install is made of hard plastic and will crack. Mine broke after so many repeated installations and removals that now I use a rubber O-ring as a substitute washer. I also suspect that there is a space between the shifter and the handlebar when I installed the sensor plug that might have caused my problem. I have since filled in the gap with some scrap bar tape. This will never happen normally as the entire system is held down by a bolt that presses onto a cap and that bolt threads into the central pivot shaft. You have to remove that bolt and the plastic cap to install the ergobrain sensor.

Reading all of this gave me a headache. I have a brand new HAC4 that is sitting on my dresser, because I want something that is simple. The above post probably made up your mind.

Precisely!

Unless you get a really good deal (like an ergobrain for the cost of a cateye astrale, as that is what it is going to be), it is not worth the sticker price.

I am now sporting the "ergo-brain delete option" on my bike setting up my old AVOCET computer for the time being, ergo-brain was a p.o.s. in my opinion....even when it works, it doesn't work.
Athough some have had better luck with it, mine sits in a drawer.
