I had the Cateye Micro Wireless on all my bikes. They were cheapish, easy to install and worked really well and I didn't realise how many bikes and computers I was going to buy before I finally caved in and bought a Garmin!

I never had a moment of drama with the Cateyes over 18months of single track use and plenty of cartwheeling action as I learnt to ride and fall off the MTB! So I can certainly recommend them. Has the usual features - I guess it just depends what you want in a computer?

I have since caved and bought the Garmin Edge 705. I seem to have been blessedly free of any issues whatsoever with it (this is me running to touch some wood right now) and it has faithfully recorded my every ride since I bought it at Christmas time.

It has been reliable in the forests and has sat quite happily on the bracket on my handlebars through almost 5months of single track, including a dusk till dawn race (where I went over the bars twice) and a 6hour race (where coincidentally I went over the bars twice) and it also lived through the 40km cycle leg of the Mooloolaba Triathlon in the pouring rain and howling wind (where I did not - thank heavens - go over the bars at all!) so I'm feeling pretty happy with the reliability of both the unit and the bracket. I have however, due to my inherent and apparent instability, put a screen protector on it to protect it from all those @#*(&%(*&^(*&(*&$@ trips over the bars!
