Round Seat Post Mount for Standard Quarter-Turn

Shipping calculated at checkout.

This mount allows you to rigidly attach your Garmin Varia (standard unit without the camera), Wahoo Trackr, Bryton Gardia, Magene L508, Outbound Lighting Blade Taillight and other devices to your bike's seat post. Please select your Round Seat Post bike model from the list. High clearance mounts are designed to clear the external seat post clamp or frame bump on the trailing edge. Low clearance are great for bikes with internal seat post clamps or a tighter fit higher on the post. Look at the pictures to help you decide which is right for you. Note the Trek specific mounts are for the older Emonda with round seatposts and can be mounted on either the seat post (34.2mm) or the frame mast (30.2mm).

Description

This mount allows you to rigidly attach your Garmin Varia (the one without the camera), Wahoo Trackr, Outbound Lighting Blade Taillight, Bryton, Magene and other devices 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! This product was proudly designed and manufactured in the USA. It is 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 hex wrench and extra stainless steel screws (because those things are easy to lose when you drop them).
Compatibility

This unit is designed specifically for Round Seat Post bicycles. Please select your bike model from the drop down list.

Compatible with the following non-camera radar units:

  • Garmin Varia RearVue 820, RTL510, RTL515, RTL516 and RVR315
  • Wahoo Trackr
  • Outbound Lighting Blade Taillight
  • Bryton Gardia - you will need to rotate the quarter turn insert 90 degrees

  • iGPSport SR mini and SR30 - you will need to rotate the quarter turn insert 90 degrees

Sheehy Labs mounts use a Wahoo branded quarter turn insert. It is a durable insert compatible with all of the radar units listed above; however, the radar unit will only install by turning it clockwise.

Installation

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. The mount will not break, but be careful not to strip the head of the screws. Try not to use a ball-end allen key as they don't work well with the small screws. Installation takes about a minute!
