The Polar s510, s710i, and s720i are more HRM then bike computer, but they do have complete cycling functions. The 710/720 even has a power kit. The Polar units use wireless sensors for speed and cadence. They are a little bulky, and are a little picky about being mounted. For tris, I wear the watch and put the speed sensor on the front wheel for best reception. I run it, in addition to a Avocet 45tt. I have decided that I like the dual setup because I can look at the Avocet most of the time for speed and cadence and then glance at the Polar to check my HR and distance.

CicloSport makes the HAC4 which is similar, they also sponsor the USPS team if that makes a difference.

Here's one recommended by none other than Dan (the man) Empfield.

The only thing I can see wrong with this is that it doesn't have cadence - but you may or may not care about that.

I've got the ciclosport. It works great. I recently discovered that my Polar watch picks up the Ciclo chest strap (but not vice-versa), so I can use it during a race.

The speed sensor is wireless; the cadence sensor (which is optional--I don't have it) has to be wired.

The HRM 1000 computer goes for $35 and comes with a strap (although I've found it works fine with my Polar strap). Basic computer & HR functions. Nothing fancy but it works great and you can't beat the $$$.

I use the Vetta V100HR.

I got it at www.chucksbikes.com for about $60-65. I've seen it sold elsewhere with the optional cadence feature for about $80. If it's something you might want to buy, don't buy it for the $100+ that some stores are selling it for. Shop around.

Anyone know if the Sports Inst. SI90 HR will pick up from a Polar strap?
