Care and Installation Instructions

Carbon Nylon is a strong, durable and heat resistance material, however it can be worn down over time from unwanted abrasion. To ensure a long life for your mount, we recommend cleaning your bike light and mount after a wet and dirty ride. Particular attention should be given to remove any sand/grit from the interface between the mount and your light.


To ensure a perfect fit of your Concentric Cycling product, please follow these recommended installation instructions:


Seat post mounts

1. Remove the nut and bolt from the assembled mount using a 2.5mm hex key.

2. Carefully flex the seat clamp open and fit it around the seat post.

3. Position the seat clamp in the desired position (e.g. at the base of the seat post).

4. Pre-install the bolt into the seat clamp (drive-side of the bike).

5. Place the light mount into the opening, and commence threading the bolt into place using a 2.5mm hex key.

6. Before threading the bolt through the other side of the seat clamp, place the lock nut into position and hold.

7. Slowly thread the bolt through the non-drive side of the seat clamp and into the lock nut until it is hand tight (max 1.5nm).

8. Do not over tighten or assemble at high speed as this may result in galling of the metal parts and/or damage to the lock nut.


Race number holder / adaptor

1. Slide in the race number

2. Insert the fixing through the race number and holder

3. Click in the locking mechanism

4. Twist/slide the race number holder into your Concentric Cycling Seat Post Mount


Head unit mounts

1. Thread the bolt into either the GoPro or Blank attachment

2. Position the GoPro or Blank attachment into the head unit mount and proceed to screw the bolt into the front integrated fitting on your handlebar until loosely in position

3. Position the rear bolt into the adjustable area and screw into the rear integrated fitting on your handlebar, again until loosely in position

4. Tighten the bolts using a torque wrench to max 2.0nm

5. If using the GoPro attachment, insert your chosen accessory and thread the bolt into the lock nut until it is hand tight (max 1.5nm).

6. Do not over tighten or assemble at high speed as this may result in galling of the metal parts and/or damage to the head unit mount and attachments.

*Note that the Cervelo S5 computer mount include a set of 4 spacers (High 2.5 & 5.0 degrees and Low 2.5 & 5.0 degrees) which can be used to further refine the position and angle of your head unit. If used, these should be placed between the head unit mount and the handlebars with the textured surfaces pressed together.

Great way to mount my radar light

I always feel silly paying for 3d prints but this one came with hardware. It works and looks sleek. When twisting the light off, the whole fixture flexes which is a little scary (so I hold it with my other hand), the clamp could shape the seat post better, I hope that it gets eventually revised for perfection

Thanks for the review and feedback. Your mount should fit snugly onto your seat post and be without any flex when you are installing your Garmin Varia. I will be in touch by email to get a better understanding of the issue and see how we can solve this for you!

Great mount

It is perfect! Love it!


Great light mount!

Excellent product

Bought this mount to replace the embarrassing mount that Garmin supplys with the varia tail light. Fits perfect with minimal profile and no weight. Customer service and dispatch was next to none.

Fits Great and Arrived Quickly

Been looking for awhile to get a seat post attachment for my Garmin Varia that would be compatible with a BMC D-post. Glad i was able to find this place that was suggested by another cyclist. Tested the attachment this morning and held up pretty well. Taylor created such a good quality attachment. Arrived fairly quickly too, considering it was coming from Australia. Will definitely order from this company again in the future.

Thanks for the great feedback! :)
