The Cervélo S5 handlebars demand a perfectly fitted mount for your bicycle computer and out front accessories. Our computer mount fulfils this need with an aerodynamic, lightweight and durable design.

Included with the mount are two fittings that allow you to run either a GoPro compatible accessory, or nothing at all - perfect for race day when every watt counts.

The computer adaptor can be used with either Wahoo or Garmin Compatible units. The unit will be supplied set up to your specification, but can be changed by simply rotating the adaptor when needed.

Manufactured in Australia from Carbon Nylon for strength, durability and heat/UV resistance. Supplied with stainless steel fixings.



Specifications (Standard):

Weight with Blank attachment = 38g

Weight with GoPro attachment = 45g

Computer Compatibility:

Standard - Suitable for most bicycle computers (up to and including the Hammerhead Karoo2)

Extra Long - Suitable for larger head units such as the Garmin Edge 1040

Bolt Spacing:

Shortened tail and bolt spacing of 14.9mm specifically for the Cervélo S5.


How to select your mount angle:

In order to have your head unit positioned horizontally, please select the relevant angle for the size of your Cervélo S5 frame. 

Note that the mount is designed to be used with the S5 handlebars in a level position. The handlebars can be tilted down by up to 5 degrees, however this will also adjust the angle of the computer mount.

To allow for this, we include a set of 3 shims. These will enable you to lower the stack height and adjust the angle of your head unit, so that it sits level and in line with your S5 handlebars. Shim angles include 0, 2.5 and 5.0 degrees.

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.


Saddle mounts

 1. If using an Apple Airtag model, place the Airtag into the base plate and pivot the cover plate into position starting from the clip side.

2. Position the mount below the mounting points on your saddle

3. Install the bolts through the mounting points and screw them into the saddle until hand tight (max 1.5nm).

4. Remove the M5 bolt and lock nut from the GoPro mount, being careful not to drop them.

5. Insert your chosen accessory or GoPro adaptor, and reinstall the M5 bolt and lock nut until it is loosely in position.

6. Adjust the GoPro adaptor to your preferred angle.

7. Tighten the M5 bolt 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 selected mounts (Cervelo S5 / BMC ICS) include shims which should be used to further refine the position and angle of your head unit. These should be placed between the head unit mount and the handlebars with the textured surfaces pressed together.

Garmin mount for Elves integrated handlebar

I requested a Garmin mount for my Elves integrated handlebar, and the service provided by Concentric Cycling was outstanding. Given that this was a new and previously unattempted design, their performance was remarkable. The communication was thorough, ensuring every detail was meticulously verified. The final product is flawless, appearing seamlessly integrated with the handlebar. Their dedication to precision and quality is commendable.

Best mount

Great quality, very solid. It accommodates both my Edge 1040 and Bontrager front light. No rattle. The best mount for my Cervelo S5.

Corey A.
Super clean mount for the S5 aero handlebars

Beautiful 3d printed mount for the Cervélo S5 aero handlebars that integrates the Garmin Varia UT800 via the GoPro mount. Couldn’t find this anywhere else and it shipped from Perth in a few days to Sydney. Incredible product.
