Recomend a standard cycle computer to use for cadence

Am looking for a cheap cycle computer, just mph nothing fancy to set up for cadence.

Any recomendations? Is wired better than wireless?

I've got a cateye wireless one that is good, real easy to st up and cost about 25quid

if on a fixed bike you can just use the cheapest computer you can find and work out the cadence for certain speeds or if it's with gears/ss get the cateye strada cadence like Branwen linked to ^^ there. You can probably find it cheaper on ebay or something. Wireless is easier and neater, but I have the wired one on my road bike and if you put care in to it then the wires are barely noticeable.
-Sumo.

Put the magnet on the pedal arm, where the steel pedal screws in, put the sensor on the chainstay.
Do the maths for wheel size /cadence

Poor man's garmin. will connect to any Ant+ sensor. so you can build up your system over time. love mine. using it with a garmin cadence+speed sensor, and plan to add a HR belt.

That was my first thought.

Go wireless unless you're planning on riding with a lot of other Strada Wireless users.

As I've just spent a few moments doing this I thought I'd share it with you all: (if you're riding fixed) how to get any old cheap cycle computer to display cadence, without having to attach things to your crank arms or anything (maybe people like attaching things to their crank arms, I don't know).

When you're setting the wheel circumference (assuming for the purposes of this that it is input in mm, if not a further straightforward conversion will be required), input the value given by the following formula:

(Sprocket teeth ÷ chainring teeth) x (number of mm in chosen display unit ÷ 60)

i.e. if your display is in mph then "number of mm in chosen display unit" is 1609344 as there are that number of mm in 1 mile (apparently) and for kms then it's 1000000; the dividing by 60 is the conversion from hours to minutes to give rpm.

Then as your cadence is likely to go into 3 figures, and cycle computers don't have a 3-figure display, you will want to divide this number by 10 so at 120rpm the display will read 12.0 usw.

This has the advantage of being able to easily reset the computer to give speed/distance etc. simply by resetting the wheel circumference to its true value, and you can leave the magnet and sensor where they are on the front wheel (n.b. this only works if your `sensed' wheel and your driven wheel are the same circumference!) It is interesting to note that the figure you input depends only on your ratio (and the unit conversions) and is independent of wheel circumference, which makes sense if you think about it but also takes a bit of getting your head around! (or it did for me at least!)

I like this idea, if you have a computer you can have two bikes on it would be great to switch between bikes on the computer which could switch between the two wheel sizes. 1st for cadence and 2nd for speed.

Garmin- uses GPS for speed (if there is no wheel magnet) and will read cadence from the GSC-10.

Move it from bike to bike to your hearts content, as long as there is a GSC-10 on there.

The Cateye Strada computers are very nice. Good quality parts just like their lights too.

I just bought this http://www.amazon.co.uk/gp/product/B002NGWMUK

I had an amazon voucher and used a sigma before and it has been great.
