The Cervélo S5 HB14 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.

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 MY23+ frame.
Note that the mount is designed to be used with the S5 HB14 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
Care and Installation Instructions
Care Instructions:
Carbon Nylon is a strong, durable and heat-resistant 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.
Our mounts are supplied with blackened stainless-steel fixings. Please use a good quality hex key when installing our mounts as worn or poor-quality tools may damage the hex interfaces. Do not combine our fixings with aluminium ones as these 2 metals corrode when placed together.
Installation Instructions:
To ensure a perfect fit of your Concentric Cycling product, please follow these recommended installation instructions:
---------------------------------------------
Seat post mounts
1. Remove the 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 and pre-install the bolt into the seat clamp (drive-side of the bike).
4. Place the light mount into the opening and commence screwing the bolt into place using a 2.5mm hex key. Before screwing the bolt through the other side of the seat clamp, ensure that the lock nut is in position and hold if required.
5. Slowly screw the bolt through the non-drive side of the seat clamp and into the lock nut until it is hand tight (max 1.5nm).
Note: 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.
7. Attach your bike light / radar and go for a ride!
---------------------------------------------
Saddle mounts
1. If using an Apple AirTag model, place the AirTag into the base plate.
2. Pivot the cover plate into position starting from the clip side.
3. 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. Insert your chosen GoPro adaptor and reinstall the M5 bolt and lock nut until it is loosely in position. Be careful not to drop the M5 lock nut.
5. Attach your chosen accessory, adjust the GoPro adaptor to your preferred angle and tighten the M5 bolt until it is hand tight (max 1.5nm).
Note: 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.
6. Go for a ride!
---------------------------------------------
AirTag combo mounts
1. Install the combo mount as per the Seat post / Saddle mounts above.
2. Place your AirTag on the insert tray with the battery side facing down into the tray.
3. Insert the tray into the AirTag combo mount with the bottom of the tray facing the front of the bike.
4. Check that the retention clip is pressed in, to ensure the tray remains in place.
5. Go for a ride!
---------------------------------------------
Front race plate mounts
1. Using the included template, punch 4 new holes into the top edge of your race plate, making sure that the timing chip will not be damaged in the process.
2. Slide in the race plate into the mount and insert the 2-pronged fixings through the front, making sure they are pushed all the way through.
3. Click in the locking clips at the rear of the mount.
4. Attach the front race plate to the GoPro attachment under your computer mount. Note that the bolt should be hand tight (max 1.5nm). If you want to be able to adjust the angle of your race place during your event, back off the tightness slightly.
5. Adjust the angle of your race plate mount ensuring adequate clearance from your front wheel.
6. Go racing!
---------------------------------------------
Rear race number holders / adaptors
1. Slide in the race number.
2. If required, mark on the race number your preferred new hole positions and add new holes with a hole punch. Once complete, reinsert your race number.
3. Insert the 2-pronged fixing through the race number and holder.
4. Click in the locking clip.
5. For adaptors, twist/slide the race number holder into your Concentric Cycling Seat Post Mount.
6. Go racing!
---------------------------------------------
Computer mounts
Our computer mounts are supplied with a selection of stem bolts of different lengths. Selected computer mount models are also supplied with shims to allow for angle adjustment. Please select the relevant bolt length depending on whether shims or a GoPro attachment are used.
1. Insert a stem bolt into either the GoPro or Blank attachment and position it into the computer mount.
Note: The GoPro attachment and Blank insert should not be used together. It is important to use the blank insert if you do not install the GoPro attachment.
2. Shims are included for Cervelo S5 or BMC ICS computer mounts. These will help to optimise the position and angle or your bike computer. Place a shim of your choice between the computer mount and the handlebar with the textured surfaces pressed together.
3. Screw the bolt into the front integrated fitting on your handlebar until it is loosely in position.
4. Position the rear bolt into the adjustable area of the mount and screw into the rear integrated fitting on your handlebar, again until loosely in position.
5. Tighten the bolts using a torque wrench to max 2.0nm.
6. 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).
Note: 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.
7. Attach your accessories and go for a ride!
