Cadence Sensor Installation Gone Wrong...
Postby Panz05 » Sat May 04, 2013 1:31 pm
I have recently purchased a new bike and have put my 810 and the cadence sensor on my new bike. I have installed it and am getting readings, but I went for a ride this morning and was averaging 11rpm whilst doing an average of 20km per hour. On my previous bike, I would average 20km per hour with an average of 65rpm for my cadence.
I suspect that the sensor has moved whilst I have been riding, but I am now questioning the way I have set it up on the bike. I am hoping you could take a look at my setup and tell me if this is ok or offer any suggestions on how to place the sensor.
The frame is different to my previous frame so I couldn't place the sensor in the same position as there was not enough clearance for the speed magnet on the spokes. If I reversed it, I could get the right clearence and both speed and cadence appeared to be working.
As a result, I had to place the speed magnet on the spoke close to the rim. The speed does seem to be accurate as I do average about 20km per hour, but because cycling is very new to me, I am not sure if this is the right position.
Any advice would be greatly appreciated.

It is reading your wheel revolution as cadence. The arm reads the information from the wheel, the body of the cadence sensor reads the readings from your crank.
Also you might want to check that your zip ties are UV rated, generally black is for outdoor use only.

The cadence magnet on the crank arm is within 5mm and the speed magnet is within 5mm of the retractable arm.
I will flip it over and play with it some more.
The white cable ties are just temporary as i already used the black ones. I have to get some new ones.
Thanks again, hopefully this afternoons ride will show up some more accurate results.

I have tested everything and it all seems to be working. I will see how it goes on my ride tomorrow morning.
Here is how it is now mounted.

My question is, why are you using those hideous white cable ties?

My Last 2 bikes had to have the arm up due to clearance. Just make sure everything is tight as required and you won't have an issue.

+1 it works really well for me.lump_a_charcoal wrote:You can buy a small magnet which will fit to the back of your pedal bolt, which allows you to remove the crank magnet + cable tie.
Well worth it IMO.

You can get them from Jaycar, or on eBay.Panz05 wrote:I would be up for that. Where can I find these magnets?

The ring magnets are slightly easier to remove if you ever need to get at you're pedal bolt, so I'd suggest starting with them.

Order a few of them, and you can always stack them together if you need a little more height to trigger the sensor properly.
