SUSPENSION
PERFECTLY ADJUSTED: How to adjust the suspension elements
To make sure that you get the maximum enjoyment out of your eMTB, you should
adjust the suspension to your body weight before you go for your first ride.
You can and the recommended settings at:
www.rotwild.de/quickstart
Follow these instructions:
-
Set the stiffness by adjusting the air pressure in each suspension element. Compress the suspension element slowly several times by around 25% of its travel to balance the air pressure between the positive and negative air chambers. Push the O-ring up to the seal of the suspension element. Sit on the eMTB when you are at your riding weight. Each suspension element should be compressed by 25 to 30% (sag) when the bike is stationary. Use the O-ring as an indicator.
-
Remove the valve cap from the suspension element and screw a suspension pump onto the valve on the fork or shock absorber. Increase or reduce the air pressure until you have reached the required sag level.
-
Now adjust the rebound damping, which determines how quickly the shock absorber rebounds after being under load. Turn the red adjuster anti-clockwise to make the shock absorber rebound more quickly. Turn it clockwise to make the shock absorber rebound more slowly.
-
Finally use the blue lever to adjust the compression damping, which determines the resistance of the shock absorber under compression, depending on the speed of the eMTB. There are three quick settings: OPEN for downhill runs, TRAIL for the best combination of damping and pedalling efficiency and CLOSE for ascents and road
riding.
You will and more detailed information about the settings in the “Suspension” section of the ROTWILD instruction manual. The enclosed instruction manuals supplied by the fork and shock absorber manufacturers contain additional information and recommended settings for compression and rebound damping.
ERGONOMICS
It is important that the saddle and the cockpit are correctly adjusted so that
you are comfortable and can make the best use of your pedalling power. This
will allow you to ride more efficiently and help prevent you from suffering
any pain.
When adjusting your eMTB for ergonomic riding, please remember that it has
cables routed inside the frame and cockpit.
SITTING CORRECTLY
How to adjust the saddle height
Seat post and saddle clamp
- Undo the saddle clamp with a 5 mm Allen key and lock the seat post at the recommended height. Make sure that you guide the cable in the seat post into the front frame opening.
- Tighten the saddle clamp again to the specified torque.
8Pins seat post
- Go for a test ride and adjust the saddle height using the dropper function or the lever on the left-hand side of the handlebars.
- As soon as you have found the right height, get off and use a 2.5 mm Allen key or the 8Pins tool to turn the rotating part through 45° anticlockwise. The height adjustment mechanism is now open. The plunger moves up.
- Close the height adjustment mechanism by turning the rotating part 45° clockwise. Make sure that the rotating part clicks back into its original position.
EVERYTHING WITHIN REACH: How to adjust the handlebars, brake lever and
shifting lever
