Suspension

I want a different fork. What do I need to take into account?
Our advice is to use the specced fork because we optimised it for the bike's kinematics and its use case. If you want to change your fork, the one you choose has to be approved for 150 kg system weight by the manufacturer. The headset is sized for fork steerer with 1 1/8" - 1,8". Please check the steerer dimensions of your new fork and choose the matching base plate. You can get the matching base plate by our dealer. The travel must be 160 mm. Also check all other standards like post mount, axle dimensions, etc. In case you are in doubt, ask your local FOCUS dealer.
I want a different shock. What do I need to take into account?
Our advice is to use the specced shock because we optimised it for the bike's kinematics and its use case. If you still want to change it, you should speak to your local FOCUS dealer and try if another one fits. As there are many shock models in the market, we cannot guarantee that another one will work. The shock dimensions are 210 x 55 mm // 25 x 8 / no bushing.
What SAG do you recommend? What is SAG?
SAG is the amount of travel the shock compresses when you just sit on your bike without moving. You adjust it with the pressure you pump in your shock with a shock pump. Our recommendation is 30% SAG seated at rear and 25% in standing downhill position up front. To see the actual percentage, you use the O-Ring that is placed on the fork and shock. Find more information in our suspension set-up recommendation.
JAM² MY25 shock set up recommendations

I want to ride with less spacers. Is this possible?
Yes it is possible to remove spacers. All cables run directly into the frame below the stem, so you don’t have to open brake lines or shifting cables when changing the height of your cockpit.
