Answering your cycling questions

Works fine on mine. I think the 5mm is playing it safe for the manufacturer.

I have one fitted to a Cube LTD Team on the front fork leg and it works ok. You can mount the magnet quite low down and angle the sensor in to suit as it is only held with cable ties.

I use my MTB as a road bike and off roader and the computer works just fine for both types. If you have standard forks you should be able to angle the sensor ti within 5mm without too much hassle.

Yes. The sensor on the front fork rotates on the mounting. I have a mountain bike with front suspension so the forks are pretty chunky but it works a treat.

I use mine on a mtb and even had some falls while the computer was fitted and it's all fine. Getting the magnet so near to the sensor was a bit tricky and I was worried that it could move while riding, but it seems to be fairly sturdy once fitted.

Yes, it will work perfectly fine.

You have the choice when you set up and can reset if you want to change.

Yoy can select Miles or Kilometers in the menu easily.

you can set it to either kilometers or miles.

It can be used in Miles or Kilometres

It does both. You chose which one you want to see.

Yes I own one and you can set it for miles or KM.

If your unsure before you but you can download the instruction sheet from the cateye website.

Yes. It has an adjustable strap to fit all sizes of bar and stem.

The mounting bracket can be mounted either on the handle bars or the stem. You need to follow the picture in the instructions, to set up the bracket in the correct way before you attempt to attach it. I decided to mount mine on the stem, which is quite large. Initally it looked like it would be a stretch, but once the strap is in place, you tighten it down by hand with a small handwheel (nut). Go for the stem if you can.

Yes, it can be mounted to the stem. No need to buy a special bracket.

Yes. Mine is fitted to the stem of my road bike

Comes with a bracket that will fit your bars and possiblly your stem

Everything is in the kit you need to fit this to any bike.

Everything is the box. No need to buy anything else.

It comes with everything you need. You will just need some scissors to cut the ends off the cable ties that attached the magnet to your fork.

I tried this on my road bike by mounting the magnet on the back wheel and the sensor on the chainstay, I then mounted the unit on the frame tube. It all appeared to work ok on the bikestand in the shed but once on the trainer it didn't want to know. I'm sure it should have worked but I didn't persevere with it as I use a Garmin Forerunner 305 as well which supplies all the data I need. The only reason I wanted to use it was to keep a track on the bike's total mileage

Think about it. Readings are derived from magnetic sensor on the Frint wheel. This relies on the Front wheel to be revolving.
On a turbo trainer your front wheel is static so you will get no reading.
It is not possible to mount sensor on rear as wireless requires sensor to be under computer on fork to pickup signal

Yes, but you need to buy a rear wheel sensor.

I can't see any reason this unit can't be fitted to any bike.

My black one has no yellow on it. It is black all over

Yes

Mine has had a good few soakings and remans problem free.

No, because the maximum distance from the computer is some 70 cm to the sensor. Unless, of course, you want to mount your computer on the seatpost then I guess it would work but that's beside the point.
