Sigma bike wired computers && stem handlebar holder
« on: July 15, 2022, 02:59:42 pm »
hi
Sigma builds an extremely beautiful and simple bike computer, the Pure1, available in two versions: wired and wireless.
I'd like the wired version because I am too lazy to check the battery on wheel sensor, and because I don't like wireless devices in general.

Sigma also builds a very nice stem handlebar holder: the 2279167504

You can buy it on Amazon, but ... will it fit the Pure1-wired?

Has anyone already tried it? can it be modified it to fit the Pure1-wired?  :o :o :o

Same question for the whole BC-line (e.g. the BC 5.16, which is cheap and great), see products here

It seems this one is compatible ... at least it lists the bc 5.16 device as supported

Yeah sadly there are various twist mount styles:  Garmin, bryton, lezyne, cateye, wahoo, giant, mio
Looks like the lower end sigma stuff is the same (BC, ATS, STS, Pure), the higher end has the symmetric style mount found here (Pure GPS, some of the Rox).

The best standardized bike mount is Gopro, but its not quick release.

I assume you are not interested in something as complex as the Magene or Xoss, due to lower battery life.

"twist mount", I like how they are called  ;D

Yup, my Garmin Edge 830 twist mount (installed on my new bicycle) is completely different to the old Sigma BC 800 (installed on my old bicycle), which is different from the Sigma BC 5.16 (made in 2016), which is different from every modern Sigma wireless devices.

Too bad for me because you need many twist mount kits.

I'd like to replace my old BC 800 because it's dead, and I specifically want the Pure1 because it's incredibly legible, containing nothing that does not belong.

Looks like the lower end sigma stuff is the same (BC, ATS, STS, Pure), the higher end has the symmetric style mount found here (Pure GPS, some of the Rox).

Yup,  but the Sigma Pure1 is available in two configurations: wired and the wireless (called ATS).

It seems a twist mount for Sigma wireless devices is less *deep?*, but I have to verify it  :-//

I assume you are not interested in something as complex as the Magene or Xoss, due to lower battery life.

ehehe no, I really want something with high battery life. My Garmin Edge 830 (GPS + touch screen, navigation + training) is very nice, but the battery lasts only for a couple of trips, say less than 190Km, and you have to charge it.

I'd like to use the Sigma Pure1 as training device, when I don't care nothing but the three most important cycling questions: { How fast?, How far?, How long? } And it does so in a very compact and attractive design, which maximizes the battery life.


Having it installed on a stem handlebar holder instead than on a twist handler would make it more comfortable and more legible during training.

so, after a lot of tries:
  • BC800 and B1200 are NOT compatible and hard to be adapted
  • PureOne wired and BC 5.16 can be adapted
nice to know  :D
