Garmin Forerunner 305 aerobar mount

I'm a big fan of the Garmin Forerunner 305.  It gives me all the numbers to make my data loving heart go pitter patter.  And mapping your travels onto the globe is like "stalking yourself", as my friend Pat once said.  Who wouldn't love that?

So when I bought my new Cervelo, I decided I didn't need any other device to tell me speed, distance, heart rate, etc.  I had it all on the little box I love.  But after one ride, it was obvious that a wrist mount just wouldn't do.  I needed a bike mount.

Garmin, following their usual practice, has announced a bike mount for the 305 but it's not shipping yet.  I didn't want to wait, so I considered different ways to mount it myself.  All seemed seriously complex and difficult, except for the "strap it sideways over the stem" approach which I've been using these past weeks. Sideways doesn't exactly enhance readability at speed.

I mentioned it to my colleague Warren (carbon fiber sailboat guru) but he felt making some carbon fiber gizmo would be overkill.  Pshaw I say, any excuse to use carbon fiber is worth it.  But I must admit he has a point.

After some research, I found that the common wisdom for mounting a Forerunner 305 on an aerobar is to use a Polar heart rate mount with a Profile Designs aerobar computer mount.  The next time I had a chance to go by REI, I picked up the parts and gee whiz, what do you know:

It works:
