Helmet cam action camera for Mountain bike or road

Since 2001, over 90,000 cyclist's have joined Cycling Forums to discuss topics from general cycling to equipment, training, racing and travel or vacation destinations (especially in europe during the tour de france). We also feature an great deals in our online store, 100's of articles, classifieds and product reviews.

A while bike there was a thread on helmet cameras
which can be used for road cycling.
I took the recommendation of a member and bought a run
of the mill SD card cam off ebay and just to surmise,
it was a total waste of money. The quality,
construction was terrible. All I got was junk footage.
About half a year ago I tried a couple of other cams
and ended up sticking with the Adrenaline Systems bike
cam. I really love this cam as you can mount it not
only on your helmet but also on your bike frame,
handlebar and even seat tube. I have gotten great
video since. The quality of their stuff is top of the
line and really easy to use, I was up and running
right after i got their package. I used my Sony
camcorder to record with great results. If I had to
get an upgrade, I would get it from these guys. They
where super helpful and patient - for me that is
either a deal maker or a deal breaker.
You can find the model I got for roadie and mtb use

I am planning on upgrading to what they call a
varifocal cam. I am still doing research on it and
will get back on it when i see how i can use it.
