Introducing CycleOps PowerCal, the worlds' first-ever power meter calculated from heart rate. For years there has been a widely recognized correlation between power and heart rate. In a lab one can predict power output or intensity by knowing heart rate, and vice versa. But once you leave the lab and enter variables such as hills, wind and fatigue, the relationship gets a bit trickier. This is why many cyclists and triathletes use both a heart rate monitor and a power meter in training.

Through the use of these tools and the analysis of tens of thousands of power files over the years, the experts at CycleOps and the University of Colorado Boulder have identified patterns which can correlate an athlete's heart rate to power across all real world conditions. We've utilized this knowledge to create a technology which provides power based on this correlation; in the real world and in real time.

No, it's not as precise as our PowerTap. Yes, it's a great tool, is incredibly easy to use, and is compatible with any existing ANT+ compatible display. Simply pair it to your display, and off you go!

We're all familiar with the key difference between a power meter and a HR monitor: that HR is a response to the work you're doing, whereas power is the actual work. The algorithms in PowerCal translate heart rate data into the vernacular of power-based training- watts, kilojoules, peak power, etc.

About the CycleOps brand

Cycleops are world famous for producing high quality cycle trainers. However, the company origins weren’t in cycling, believe it or not they started with producing curtain rods! The story goes that the Graber brothers sold their window products company and needed something to do. They experimented in their garage and came up with a best-selling bike rack. In 1989, Chris and Sara Fortune purchased the company when it was selling 80,000 bike racks a year. In 1990, a high-end brand of bike rack was launched, branded as “Saris.” Today Saris is a leading supplier to the bicycle industry in over 30 countries. The company expanded in 1999 by acquiring the Cycleops brand of bike trainer. As usual they set out to improve on the design and by 2001 they created a new trainer frame and in 2002 they launched the world’s first progressive resistance Cycleops magnetic trainer. It was in 2001 that they heard about a hub that could measure power output and they jumped at the chance to bring this product to cyclists. They bought the company that invented Powertap and started a new round of Cycleops cycling innovations.

CycleOps PowerCal with Speed Sensor 3.2 5 5 5

Inaccurate and unbelievable data I bought this realising that is isn't a true power meter and cannot be compared with one. What I did expect was an accurate heart rate reading which in turn would give a believable power number, even if the numbers produced could not be compared to a powertap - as long as the wattage remained consistent to me, it would be ok.. Unfortunately the HR figures are so far out from what I would normally expect to see, the power numbers were complete rubbish. This leads me to believe the calibration of my unit was completely wrong. Having read various reviews on this product it did seem to be a bit of a gamble as it appears to work for some people and not for others. It did not work for me, so I will remain power dataless. 09 May 2013

A useful bt of kit I was intrigued to discover that I could get a sense of power from this neat bit of kit and I like to have numbers to occupy me when cycling AND I wanted to train to power a bit more so this seemed sensible as a starting point. I knew that it would not be like have an SRM meter in the cranks or a Powertap - but it is a fraction of the price. Hooking it up to my Garmin 800 was straightforward although I always find the Garmin menus a bit fidly and cant quite remember where everything is. But the basic connections to this as a monitor for both heart rate and power was easy. Got the displays changed and off I went. The power read out was a bit volatile to begin with but after a while it seemed to settle down and on my second and third rides was giving quite stable output - I set it to the average of the last 30 seconds otherwise I thought it would bounce all over the place. Of course I think the readout is low (if Bradley Wiggins can don 550W for a one our time trial, surely I can produce more than that!!) Overall a good bit of kit and neat addition to my gear. Only gave a 3* on value because it feels price for what it is - but it is a lot better value than the alternative. For a sense of relative value of power output it really does good work. 16 March 2013

Great start to using power The PowerCal doesn't give you the kind of accuracy that other expensive power meters are known for. But it does an amazing job for the price. Don't expect the instantaneous power readings to be correct from the PowerCal but if you look at averaged power over 30+ seconds then values are very representative. So don't expect to be able to measure power output for short hard sprints. I am just starting to learn about training with power and for me this is the right tool at the right time for the right price. I had been using Strava estimated power and it just wasn't giving me what I needed. The values that I am seeing from the strap are tallying quite nicely with figures I have from sessions on a Computrainer and give me confidence in using this as a training tool. So this purchase is going to allow me to wait for 6 months+ whilst the next batch of power meters are released to market (Garmin Vector etc). Plus, I gain a good insight into getting the most out of using a power meter - what could be better! 25 November 2012

Does what it says on the packet This is for the non speed-sensor version - I have speed already on my Garmin. If you want an accurate moment by moment measure of your actual power, this isn't it. But if you want something that will give you good, reliable, repeatable figures for ride totals, or periods of rides, it's great. Actual values need to be taken with a grain of salt, but it's the same grain of salt every time, i.e. the relative values are accurate. A great way to get into the world of power training, and opens the door to the more exact management of riding and training that use of power offers. Excellent HR strap as well, easily the most comfortable I've ever had. 27 September 2012

Answer:

I have a Magellan Switch Up and this works fine. If you have a look at the ANT+ website it mentions the Garmin Edge 500 as a compatible device.

Answer:

I use it with an Edge 500, works fine - to the extent that Garmin units work fine with Power transmitters.

Not convinced that the way Garmin handles power data is as sophisticated (accurate?) as the dedicated head units from manufacturers of power units themselves (e.g., Joule). As a for example, Edge displayed TSS is not the same as what Garmin's own software gives when the (same) data is imported.

Answer:

I have used the Powercal with the Garmin 800. There is no reason that the combination the Garmin 500 and the Powercal should not work.

Answer:

In the product description it says "compatible with any existing ANT+ compatible display", this should include the Garmin Edge 500 - but it might be worth checking with the manufacturer first.
