Headset
Droplink bikes are designed to use an external type bottom cup (regardless of steerer size) to maintain the geometry
of the bike. It is possible to install a 1 1/8” steerer fork using a crown race adaptor. Installing a 1 1/8” fork using a zero
stack bottom cup will steepen the geometry and drop the BB height. It will also result in fork crown adjusters not
having sufficient clearance from the down tube, thus allowing potential damage the frame and fork if the bars are
over-rotated. ZS44 lower cups are therefore not approved.
Specifically it is not safe to install a longer travel than recommended fork (eg 180mm travel or more on a Rocket) with
a 1 1/8” steerer and ZS44 bottom cup thinking that because the overall length of the system is similar to the approved
EC44 bottom cup/max fork length set up it will be safe. It won't. No matter what the headset-steerer combination,
forks longer than the maximum stated in the table above are not approved.
Use of offset bushings in the shock to alter the geometry is prohibited and invalidates the warranty. The tyre clearance
at full travel is not sufficient to allow the use of offset bushes and presents a danger to the rider and the safety of the
frame if used and invalidates the warranty.
Seatpost
The seatpost size is 31.6mm, using a 34.9mm clamp. Hose routing is provided along the down tube and through a
hole in the seat tube for internal or 'stealth' routed seatposts.
For internal 'Stealth' routed seatposts, the routing hole is on the front of the seat tube above the bottom bracket, but
below the droplink. Feed your remote cable/hose through by anchoring it to the outer cable pre-installed in the frame
and install as per the seatpost manufacturer instructions. Once installed, wrap the supplied Jagwire routing grommet
over the cable/hose and push into the seat tube hole until firmly in position. This will prevent water ingress at this
point.
To prevent frame damage, the seatpost should have a minimum of 100mm of insertion into the frame below the top
of the seat tube with the saddle set at the maximum height required by the rider, regardless of any minimum insertion
marker on the seatpost.
Failure to observe this minimum insertion of 100mm will result in premature frame failure and invalidation of your
warranty.
It is important to check and ensure that you can insert your dropper seatpost far enough into the frame to get your
correct pedalling height.
For maximum insertion measurements for your frame to check dropper post compatibility, please check the latest data
on the geometry chart on the product page of the website at www.cotic.co.uk.

It is possible to fit various brands of angle adjust headset to the Cotic Droplink frame. Whilst this does not invalidate
any warranty, it does move the handling away from the layout we spent a great deal of time researching and
perfecting. We accept some people have different preferences to the handling of the bike, and all we ask is that you
proceed with care if fitting an angle adjust headset and take time to learn how the bike handles differently.
