data loggers

Perhaps, this is what you are looking for?

I am not sure how it gets speed+distance. You may have to get the GPS
based speed sensor to use with it.

Polar 720i:

Logs speed, cadence, heart rate, altitude.

Ciclosport HAC4:

IMO, the Polar's a better unit. I've seen too many problems with
owners of the HAC4.

A Polar 720i and similar models will do this, although cadence takes
an optional cadence kit. Data can be sent to a PC over an IR link.
Unfortunately, these are fairly expensive, but can sometimes be
found on sale.

A PowerTap Pro hub will do this also, as well as logging your actual
power output in watts. It is far more expensive, and probably not
worth it unless you are quite serious about training for racing, or
have a lot of spare money, and a fondness for gizmos.

There may be some cheaper HRM's that will do what you want; I
haven't researched it. You'll have better luck checking out high-end
heart rate monitors and cyclocomputers than searching for data
loggers.

I have a Ciclosport CM 436m which records all of the above except HR. It
works very well but the documentation for the software is weak. It took a
day or so of messing with it to figure it out. It came with two software
packages: HACtronic and CicloTour. The data can be exported from ciclotour
to txt or excel (except cadence). The HACtronic software will not export the
data. They seem to have taken special pains to prevent exporting data - you
can look at the numbers in HACtronic but you cannot cut and paste or export
them. The price has come down.

I also have a Garmin Forerunner 201. A GPS thing that can be worn on the
wrist. It is designed for runners. It will display speed, distance, etc but
not cadence and HR. It will export the data as a list of coordinates and
elevations. The Garmin Fortex 101 is a similar unit intended for hikers.

I have simultaneously taken both units on several rides and they recorded
the distance to within about 0.5% of each other. The displayed speeds jibe
well also.

They both provide amusement and I can sometimes motivate myself to do a
long, hard ride for the purpose of gathering a good data set. Perhaps I am a
gizmo geek.

Curious what problems you've seen with owners of HAC4 units. I haven't
noticed much difference in the people buying either a HAC4 or a Polar 720i
(or the latest, 725).

The main issue with the HAC4 is the attachment of the main unit to the
frame. Seems they just can't seem to get it right, and one way or another,
they find ways to detach themselves on bumpy roads. The Polar, on the other
hand, frequently has problems with the transmitter for cadence; in my
opinion, wireless cadence remains a dream, not a reality. The distance from
transmitter to receiver is too great for a low-power (long battery life)
unit.

When everything is right with both units, the HAC4 excels with a spot-on
altimeter, while the Polar has the edge in actual data recording (the HAC4
records only at 20-second intervals, while the Polar can be set to record
every 5 seconds).

Not sure if you're interested in something for the bike, or a program for
logging and analyzing your rides and training. If you're interested in the
latter, you might find my CycliStats program useful. It allows you to
easily track your rides (including distance, time, cadence, heart rate,
elevation gain, etc.), plus it automatically estimates your calories burned
and average watts for each ride.

In addition to your ride data, CycliStats also allows you to track your body
weight, blood pressure, and resting heart rate, and bike maintenance.

Featuring an easy-to-use interface, with a lot of built-in reports and
graphs, version 1.8 of CycliStats was rated 4 stars (out of 5) in a review
last year by noted cycling author Fred Matheny (
http://www.roadbikerider.com/pr9.htm#CycliStats ). The current version of
CycliStats (4.2) has many new features that weren't included in Fred's
review, including a new "Goals" feature (
http://www.shastasoftware.com/CycliStats/goaleditor.htm ), and a very handy
"Calendar" view (
http://www.shastasoftware.com/CycliStats/calendartab.htm ).

You can download a free, fully functional, 30-day trial version of
CycliStats from the website ( http://www.CycliStats.com ), to see if it
meets your needs.

The cadence has never caused any problems for me on any bike or Polar system
in the past 7 years (including the Xtrainers).

How large is your frame? And you've been using the default (low-power)
setting?
