Kona power meter usage trends: 2009 to 2017

Update for 2017 based on the Lava Magazine bike count data. Previous posts links showing trend data up to 2013, 2014, 2015 and 2016 are here:



This chart shows the trend in relative usage of power meters since 2009, along with the total number of bikes (click  on images to see larger versions):



Here are the numbers. Data in order of year of introduction.:




In the nine years of this data being available, power meter usage has risen from 17.3% of all bikes to 58.7% of all bikes, although the growth slowed  this year, and was well below the longer term trend of an increase of 5.5 percentage points per year.


Finally the year on year change data and order ranking:


Not too much change to report compared with last year.

Stages is the big loser this year with the largest fall in both overall numbers and in relative share, dropping one ranking place from 4th to 5th most commonly used meter at Kona.

For another view, DC Rainmaker has this year done a similar analysis.

Kona power meter usage trends: 2009 to 2016

Update for 2016 based on the Lava Magazine bike count data. Previous posts links showing trend data up to 2013, 2014 and 2015 are here:

Here are the numbers for 2009 through to 2016 (click  on images to see larger versions):



And below is the breakdown showing proportion of bikes with and without power meters, and the split for each power meter as a proportion of all bikes. e.g. the slice of pie for the Powertap is 175 Powertap power meters which is 7.9% of the 2,229 bikes in the the Kona bike count.



2016 continued the long term trend of an increase in use of power meters by Kona IM athletes, and for the first time ever a majority of bikes (57.4%) were fitted with a power meter.

So the pie is getting bigger for all power meter manufacturers. at least as a share of Kona athletes. How indicative these numbers are of broader power meter trends is hard to say.

So how are they all doing as a share of that increasing Kona power meter pie slice?

Below are the year on year trends, ranked by total share of power meters:


Quarq and Garmin Vector maintained their lead as the most used power meters and like most brands each saw a small increase in their share of the total power meter pie. However their relative share of the bikes fitted with power meters took a hit with Quarq dropping 3.4% to 23.7% and Garmin Vector down 3.0%, to 17.8%. These were the biggest falls in relative share of all the major power meter brands. While this continues Quarq's trend from the previous year of a decline while still maintaining top place, it's a reversal of fortunes for Garmin Vector who showed strong year of year relative share growth last year.

The big mover up the rankings was Powertap which like most brands improved its share of all bikes but more importantly their share of bikes fitted with a power meter was up 6.4% to 13.7%  (nearly doubling their 2015 share). This is no doubt due to the introduction of Powertap's new power meter models, in particular the P1 pedal based meter, which complements their well established hub-based and new C1 chain ring-based power meters.

This reversed the trend in recent years for Powertap, whose numbers were probably a little under represented as the Powertap hub is the one that most likely to be used as a training wheel for some athletes but not as a race day wheel. Unfortunately the Lava Magazine data does not parse the Powertap data into model sub-categories so we can't know exactly the trends for each model, however the pedal count shows 82 bikes with Powertap P1s, which means hubs and chainrings (if any) make up the 93 remaining Powertap models. In 2015 Powertap hubs numbered just 78 units.

Rotor and Pioneer also saw their share of all bikes and all power meters improve, although from a smaller base.

Stages share of the Kona power meter pie has stabilised after strong growth from 2014 to 2015, with a slight drop in their relative share of power meters.

Power2Max is declining in their relative share of power meters used at Kona and this is the second year they have experienced such a decline.

SRM continues its slow drop in relative share on all bikes and of those fitted with a power meter.

A few new power meter brands make a guest appearance but none have really exploded onto the Kona scene.

Overall observations

These numbers continue the broad trends of previous few years:

i. Power meter usage as a proportion of all bikes used at Kona continues to rise at a rate of nearly 6% year on year. This has been a consistent trend since 2009. If the trend continues, we should expect that in 2017, approximately 63% of all bikes will be fitted with power meters.

ii. Most growth in usage comes from newer power meter models.
For 2016 the majority of growth came from Powertap with 45% of the growth, Rotor 21% and Stages 11%, with the rest making up the remaining quarter of the growth (SRM being the only model with negative growth).

iii. after an initial period of growth, models tend to stabilise their Kona athlete market share for a year or so before beginning a gradual decline in share

iv. no power meter model dominates Kona athlete market share. Quarq maintains its place as the lead choice being fitted to 23.7% of bikes with power meters.

Some caveats:
- obviously this is a sample of athletes that qualified and participated in Kona and hence we can't simply project these trends as necessarily being representative of the overall market.

- the  athletes that qualify obviously changes from year to year.

OK, so that's the latest on power meter usage trends from Kona. See you in 2017!

Kona power meter usage trends: 2009 to 2015

Update for 2015 based on the Lava Magazine bike count data. Previous posts links showing trend data up to 2013 and 2014 are here:

Without further ado, here are the numbers for 2009 through to to 2015 are (click on images to see larger versions):






In brief, 2015 continued the long term trend of an increase in use of power meters by Kona IM athletes, with a tick under half of all bikes now fitted with a power meter.

The two longest established brands, SRM and Powertap, have further fallen away in absolute numbers as well as total share dropping with Powertap suffering the biggest drop in usage, and while Quarq is still the most used meter, its absolute usage has reached a plateau and it is no longer as dominant a power meter brand for Kona IM athletes as it has been in the past few years. It will be interesting to see how Powertap fares in the years ahead with the introduction of their new pedal and chainring based meters.

The use of power meters is more evenly distributed across the various brands than in previous years, with no brand dominating share of usage on Kona IM athlete's bikes.

Newer power meter brands have increased their presence significantly, in particular Garmin Vector and especially Stages being the big movers.

Power2Max maintained their 2014 share of the power meter pie, while newer offerings from Rotor and Pioneer make up the smaller slices.

Edit:
Thanks to Prof. Hendrik Speck of Hochschule Kaiserslautern University of Applied Sciences for picking up a couple of very small errors in the Polar power meter numbers I had listed for 2009 and 2013. I have updated the table and chart above. I also left the linked posts from previous year's summaries uncorrected so that a record of the small error remains.

Power Meter usage still on the rise at Kona

Last year in this post I put together a chart showing the trends in power meter usage at the Kona World Ironman Championships since 2009.

Lava Magazine have once again done a complete bike and equipment count for Kona 2014, and I've been looking at the power meter part of that count. The data I have is preliminary as posted by Brad Culp of Lava Magazine. I'll post the online link with the count data when available.

2014 Kona IM Bike Count

Here's an updated chart and table for the six years from 2009 to 2014. Just click on the image to see a larger version.



In brief, we can see there has been a continuation of the strong trend in use of power meters, with 45% of all bikes now fitted with a power meter.

The two long established brands, SRM and Powertap, have fallen away a little in absolute numbers as well as total share dropping, while Quarq usage has grown again and it remains the dominant power meter brand for Kona IM athletes with more than double the usage of the next most popular brand, SRM.

Most of  the growth in total power meter usage is attributed to the use of newer power meter brands, with Power2Max, Garmin Vector and Stages being prominent in increasing the overall size of the power meter pie.

Speaking of pies, here is the 2014 breakdown in pie form:



It's interesting to note how evenly split the major power meter brands are.

What will 2015 show? I guess we'll see the number of bikes with power meters out numbering those without for the first time.

Power meter usage on the rise at Kona

The Kona World Ironman Championships is over for another year. As part of event registration, the organisers do a count of equipment choices, and this includes power meter brand if fitted to a competitor's bike.

So just for fun, I thought I'd look at the prevalence of power meter usage by Kona competitors for the last five years, including this year. I managed, with a little help from the wattage forum and Google, to locate the data and compiled them into table and chart form. Click on the images to see a larger version.



So while competitor numbers at Kona increased by 36% over the five years 2009-2013, the number of power meters installed on competitor's bikes over that same period increased by 174%!

We can see three major power meter brands: SRM, Powertap and Quarq, have dominated the Kona power meter landscape to date, with Quarq in particular showing strong growth over this period.

Power2Max have begun to make inroads in recent years, and we can also see the emergence in 2013 of newer power meter offerings from Rotor, Stages and Garmin. The old Polar power meter is a distant memory, and ergomo usage never really got going, although a few souls were still using them up to 2012.

It appears the overall solid increase in usage of power meters by those competing at Kona has largely been satisfied by uptake of newer power meter brands. It would be risky to assume this translates directly into general market trends for power meter usage but it certainly provides a good snapshot of the trends for Ironman athletes.

The data on total bike numbers and power meter counts were obtained from these website links by Lava Magazine (2010-2013) and Triathlete Magazine (2009):
