Garmin GSC10 problems – the saga continues

Saturday, August 25th, 2012

I decided to purchase another GSC10 as I was keen to see whether its lack of waterproofing had been fixed by Garmin (for the background here is my previous take on this, see  Garmin Gsc10 problems).  Also the replacement unit sourced from the German  company o-synce had failed after working for a couple of years  (see MACRO 2SXcom speed and cadence sensor).

The new GSC10 was delivered from Wiggle a month ago and fitted to my bike. To get it working all I had to do was to change the wheel magnet as they don’t seem to be compatible, neither will work with the speed sensor from the other company which seems odd, a magnet is a magnet after all. My Garmin Edge 705 picked up the cadence sensor right away with no problems and it all worked well together.


Garmin Vector power meter pedals

Thursday, August 18th, 2011

At last Garmin have announced details of their power meter pedals, see the details at Garmin brings power to the people with vector

Garmin Vector power meter

Could be the ideal power meter solution as you can change your pedals easier than cranks and it doesn’t involve having to swap a wheel across bikes (which can be a faff with brakes, cassette etc.) so this can be portable between several bikes.

The Garmin website says it is ANT + compatible but to get the best data set you need a Garmin 500 or Garmin 800.  That means that to get the most data such as left and right power balance and other metrics you will need one of these units, but presumably those of us with older models such as the Edge 705 will still get the basic power data if we purchased a pair of vector pedals. These are not exactly cheap at a suggested retail price of $1,499.99 US dollars, how that will translate into sterling or euros remains to be seen.

The blurb on the Garmin website says:

Quick and easy: For many cycling enthusiasts, purchasing a power meter is an intimidating and  potentially complicated process, often involving mechanical tradeoffs for their bikes. Vector simplifies the decisions and the process. Cyclists can now walk into their local bike shop, walk out with a Vector power meter in hand, and install it themselves in minutes.
There’s no need for a custom order process, no need for a mechanic, and no downtime while their bike is in the shop. With integrated cadence measurement, there are no external sensors to install, and all calibration is performed before the Vector power meter hits the store shelves. Vector’s easy-to-install design makes it easy to swap between bikes, and easy to take to out-of-town events when renting or borrowing a bike. Vector’s light weight and durable injected carbon fiber pedals are LOOK Keo compatible, and its ANT+ wireless pedal pod transmitters fit most major cranksets. Vector has also been designed to be easy to update as software enhancements are made, thanks to its ANT+ wireless technology.

Updates to Garmin Connect

Sunday, November 21st, 2010

The Garmin Blogs mention that there have been updates to Garmin Connect that include a change of map supplier to Microsoft Bing. The maps look attractive enough and look to have the same level of detail as the Google versions that were used previously.

I download my rides from the Garmin to SportsTrack which has some great features for tracking activities and also an active community of users developing plugins.

It does however have some problems, it is a Windows application that runs on PCs and does not have a web based interface. The other problems are that it does something strange to elevation data and up until recently did not show timed stopped or paused. (more…)

MACRO 2SXcom speed and cadence sensor

Saturday, October 16th, 2010

The problems with waterproofing the Garmin GSC10 has led me to search for replacements.
There don’t seem to be many options but one that seemed possible was the MACRO2SXcom from German company o_synce. These units are ANT+ compatible and should work with the Garmin 705. They are also cheaper at £29.99 each versus £39.99 for a GSC10 (prices are from Wiggle, there may be cheaper deals elsewhere).

MACRO25SXcom speed and cadence sensor

In the box there is a speed sensor and separate cadence sensor that are linked by a short length of cable. The speed sensor has a separate rubber base that protects the chainstay. There are also wheel and crank magnets and five zip ties to attach all of this to the bike.
The separate speed and cadence sensors do make it more fiddly to install, but on the other hand it does allow for more precise positioning and makes it easier to get the sensors within the specified 2-4 mm distance from the magnets.
To get the unit paired with the Garmin 705 was easy once I had read the instructions that tell you to open the lid on the speed sensor and flip the battery over. It was then found by the 705 with no problems. I did have to replace the Garmin wheel magnet with the one supplied by o_synce to make the speed sensor work. The cadence sensor manages fine with the original magnet from the GSC10. (more…)

Quebrantahuesos 2010 Cold and Wet

Sunday, August 8th, 2010

Perhaps the fact it rained pretty much all the way down  through France to the Pyrenees was a warning of things to come.  Our hotel was in Canfranc Estación which is near the summit of Somport,  the first climb in the Quebrantahuesos, this was a good location for the normal very hot conditions as it was high up on the mountain, but pretty cold and gloomy with the weather this year.

On the morning of the Quebrantahuesos it was raining as usual at the hotel but became warm and sunny as we drove past Jaca towards Sabiñanigo. Ever the optimist I changed out of my three-quarter bib-shorts and left my waterproof jacket behind in the car.

QH 2010 ready to go

At least I had enough sense to wear a gillet and arm warmers, and then it was off to the start in Sabiñanigo.

This was all it had promised to be, great atmosphere with thousands of very fit looking Spanish club cyclists lined up in a huge queue. They were all wearing full club kit sponsored by their employers with shaved legs shiny with embrocation, they really looked like they were ready for business.

A few minutes before the start helicopters came roaring low overhead which added to the sense of excitement. Then at 7:30 am the gun went and those in the front pens (reserved for celebrities and people with good times in previous editions) started off, it then took 10 minutes or so before my part of the queue passed over the timing mats.

Garmin GSC10 problems

Garmin GSC10 cadence sensor

For an updates to this article with news of the current GSC10 see Garmin GSC10 the Sage Continues.

The otherwise excellent Garmin 705 is let down by the GSC10 speed and cadence sensor. This unit is not properly waterproofed and eventually fails completely. You can revive it once or twice by drying it out but once water ingress causes corrosion or electronic failure the cadence sensor becomes a piece of junk.

It is mystifying to me why Garmin do not correct this problem. The solution is to properly waterproof the unit, surely that cannot be beyond the capabilities of this technologically sophisticated company? (more…)

Garmin Connect embed feature

Saturday, April 3rd, 2010

There is a new feature on Garmin Connect that allows you to embed details of an activity in a web page or blog. It seems pretty easy to use. Make sure  the activity is shared by clicking on the padlock on the Garmin Connect Activity Details page.

The click on the Embed icon below the activity map, this will generate some html which you then paste into your preferred web page or browser as seen below. You can click on view details below the map to link to the shared ride on the Garmin Connect website.

So here is the training loop I just did today:

Garmin 705 reset

Garmin 705 Reset

One of the things that bugged me about the mostly excellent Garmin 705 was the fact I could not get it to reset after completing a ride. So unless it was synched with a PC it would extend the previous ride rather than starting a new one, even if there was a large amount of time elapsed between the two rides. Even doing a reset would not force it to save the current data and start from zero. Having to sync to a Pc every time was tedious to say the least and the manual gave no clues as to how this could be done. Then browsing the web yesterday the solution was there posted on at

Garmin Edge 705 Tip – Save the last ride and reset

The solution is simple and kind of intuitive, just press the Lap button for a few seconds and you get a countdown to zero with the message saying Reset in: with a countdown from three down to zero. You have to keep your finger on the Lap button until the countdown has expired.

And that is all that is required, kind of makes you wonder why Garmin didn’t add this to the owners manual and save us all a load of time and effort, this is something that presumably just about everyone who owns one of these devices will want to do?
