This mount allows you to rigidly attach your Garmin Varia (the one without the camera), Wahoo Trackr or Magene radar unit to your bike's seat post. The mount uses the standard quarter turn system found on many Garmin and Wahoo devices. This is one of the lightest and most aerodynamic mounts on the market with a sub 16g weight. 

This mount is designed for Giant bikes. Select your model from the list of styles.  The 2024+ model only fits the Giant Variant seat post.  This will not fit the Contact SLR D-Fuse seat post.  See sheehylabs.com for other bike brands or to mount the Garmin Varia with the camera.

Compatible with the following non-camera radar units:

  • Garmin Varia RTL510
  • Garmin Varia RTL515
  • Garmin Varia RTL516
  • Garmin Varia RVR315
  • Wahoo Trackr Radar
  • Magene L508 - you will need to rotate the quarter turn mount 90 degrees

Precision printed with fiber reinforced nylon that makes it both durable and flexible.  The matte black finish looks great on any bike. Each unit comes neatly boxed in plastic-free packaging and includes a 2mm allen wrench and an extra stainless steel screw (because those things are easy to lose when you drop them).

Easy to install.  No need to remove your seat post!  Just remove the two preinstalled stainless screws using the included 2mm allen wrench, open the mount and wrap it around the seat post.  You might have to give it a bit of squeeze to line up the screws with the holes - they go in at a 45 degree angle which provides excellent clamping strength.  Tighten the mount until the gap is closed and then tighten some more to ensure the mount doesn't slide on the post.  Try not to use a ball-end allen key as they don't work well with the small screws. Installation takes about a minute!

Compatibilité Giant TCR ADVANCED 2025

Bonjour,
Est ce que votre support est compatible pour une tige Giant Variant, composite, -5/+15mm offset ?

Hi Nicolas! Yes, it is compatible with the Giant Variant, composite, -5/+15mm offset. Select either “TCR Advanced Variant 2024+”, “TCR Advanced Pro Variant 2024+” or “LIV Langma Variant 2024+” they are all the same mount. Let me know if you have any more questions.
