Technical data

Weight 26 Gram (including. bolts for stem)
Material aluminium, CNC milled
Colours black
Compatibility all Garmin cycling computer including GARMIN Edge 1000, Sigma Rox 12
Content of delivery PORTEUR including Di2 mount and M5x23 titanium bolts



Our proud Tune hearts suffered greatly when we had to attach the first Di2 junction boxes with cable straps to our beautiful stems. And to add insult to injury, we had to add a plastic mount on top of our sculptured stems for the Garmins as well….

Naturally, a proper integrated mount was the logical solution.

Our objective was simple; a functional, tidy and light mount that integrated perfectly, and we feel we were tremendously successful with the Porteur. A CNC milled Aluminium plate forms a single unit with your Geiles Teil 4.0, and will keep your Garmin safe, under even the toughest conditions.

The Di2 junction box can be mounted underneath for further efficiency.

The Porteur is attached with titanium bolts (included) to the stem face plate.

tune FAQ

Porteur by Tune: How do I install a GoPro adapter?

Is our PORTEUR compatible with other stems?

Yes, it is. But please note that mounting the PORTEUR affects the static of the stem. So we can only guarantee a perfect function in combination with our stem "Geiles Teil 4.0 Oversize". Porteur Zeichnung  

Can I mount a lupine piko lighting system on the PORTEUR?

Yes, it is possible. To attach the light is our gopra adapter, as well as the gopro adapter needed for lupine.

Can I use the PORTEUR to attach my navigation system over the stem?

Yes, it is possible. Technically, there is nothing against turning around the PORTEUR and attaching it to the two upper screws of the stem so that the GPS stands above it.

Which bicycle computers is the PORTEUR compatible with?

Our PORTEUR is compatible with all Garmin devices, as well as Sigma Rox 12.0. Other devices, such as Wahoo, have a different screw guide when the adapter, which preclude compatibility with our PORTEUR.

    Test tune porteur

    The cycling magazine GRAN FONDO has tested various GPS mounts, including of course our TUNE Porteur. The magazine especially emphasizes the very high-quality workmanship of the porter. Also the clever expansion possibilities, for GoPro, Di2 or light, are felt as very good. The high stability of the light Garmin holder is also positively noticed: "Very solid - the Porteur also has heavy equipment very well under control".
