Setup Suggest ons
The suspension on your Cotic Rocket is designed to work at it’s best when the suspension ‘sags’ with the rider on board the bike.
'Sag' is the amount the shock compresses compresses with a rider on board. The Cotic Rocket's suspension works at its best when
set with between 25% and 30% of the available travel as sag.
You should be looking to set up your bike between the following:
25% Sag: 14mm Shock stroke with rider on board.
30% Sag: 17mm Shock stroke with rider on board.
How To Set Your Sag
Using a shock pump, set your shock to the following pressures depending on shock type:
Fox - 170psi Marzocchi - 110psi BOS - 230psi
Leave your forks as they are (if you've already set them up) or put in the recommended spring weight/pressure for your weight
from the manufacturers manual.
Adjust the rear shock's rebound and compression damping adjusters to their minimum setting. This allows the shock to compress
unhindered and ensures a more accurate sag measurement.
Put your riding kit on. Or at least a fully loaded backpack if you usually ride with one. Set the saddle to your correct pedaling height.
Mount the bike and go for a quick ride in a suitably quiet area. Whilst riding, bounce on the saddle a couple of times to get the
rear shock compressing as much as you can.
Then, whilst seated, pull the rubber o-ring up against the shock body and very gently roll to a halt, preferably without using the
brakes. We find rolling to a stop alongside a kerb helps as you won't easily accidentally compress the suspension when dismounting
the bike.
Once off the bike, measure the distance between the o-ring and the shock body. Adjust the air pressure in the shock accordingly
to get the desired amount of sag. Note that the BOS Vip'r shock requires higher pressures than you may be used to, the Marzocchi
Roco Air LO is lower pressure than you might expect. For example, for Cy (who weighs 85kg), the Fox shocks run around 190psi.
The BOS is set around 250psi, the Marzocchi around 120psi.
It’s worth noting that as the weight distribution of all bikes is different, being dependent on saddle position, stem length and bar
width amongst many other things. It’s quite possible that with the correct sag at the rear of the bike, your forks may end up with
too much or too little sag because there’s more or less weight on them compared to your previous bike. This is why we don't
recommend any particular pressures, because even quite subtle differences in your saddle/cockpit set up compared to anything
we measure will result in different pressures being required for a given level of sag. This is why we always recommend setting up
using sag as your guide, not a generic shock pressure.
Once you’ve set the rear sag, check the front fork sag. If the fork sag requires alteration, alter it, then check the rear sag again.
eep doing this procedure until both front and rear sag is set as desired by the rider, within the manufacturer recommendations
for the frame and fork.
The Rocket is a bike for hard riding. As such, we recommend running a firmly sprung fork setup with 20-25% sag coupled with
30% sag at the rear for general riding. The firmer forks keep your weight centred on downhill sections. The progressive nature of
the Droplink rear suspension means running 30% sag gives lots of grip and fluidity whilst still having great support when moving
the bike around.
