Frequently asked questions

Depending on the frame size, we use different spring rates.


S: 225 lbs
M: 250 lbs
L: 300 lbs




These spring rates roughly reflect the average rider weight per frame size. We recommend a sag value of 30% - 35% for the EXTRA. If you can't achieve this sag value with your weight, we suggest using a different spring rate. In the table below, you'll find the spring rate we recommend based on your body weight. Additionally, you'll find the stroke and length of the springs, allowing you to order the right spring for you. 

The EXTRA Coil and the EXTRA Air share the same frame platform, which means you can install an air or coil shock on both frames, regardless of the color. If you prefer, you can also equip your EXTRA Air with a 170mm fork, or alternatively, equip your EXTRA Coil with a 160mm fork. Additionally, we specify the EXTRA Air as a 29" bike from the factory, and the EXTRA Coil as a Mullet, meaning a mix of 29" in the front and 27.5" in the rear. However, you can always switch between configurations based on your personal preference. 

You can get the EXTRA Coil as a complete bike in a Mullet specification, meaning a combination of 29" and 27.5" wheels. Here, we set the FlipChip to the High/27.5" position. If you prefer a very low bottom bracket, you can also switch to the Low/29" setting, but be prepared for occasional pedal strikes ;-)


Our EXTRA Air comes as a complete 29" bike from the factory. We initially set it to the Low/29" position for perfect bike positioning with a low bottom bracket. However, for more ground clearance and slightly more agile handling, you can also use the High/27.5" setting. We don't recommend the Low/27.5" setting with a 27.5" rear wheel, as the slightly shorter 160mm fork makes the bottom bracket even lower, bringing the cranks quite close to the ground. 

With the new EXTRA Air and Coil, you can use up to 180mm of front suspension travel. From the factory, we install 160mm (front/rear) for the EXTRA Air and 170/165mm (front/rear) for the EXTRA Coil in the complete bikes.

Yes, that is possible. We have thought of two cable exits on each side. 

No, by introducing the 55mm chainline, we were able to create enough tire clearance, allowing you to use a standard 12x148mm rear wheel.  

The EXTRA is approved for a system weight of 120 kg. With the ASTM 5 classification, it is also suitable for use in the bike park. These approvals apply to the frame. In some cases, we use components, that are only approved up to ASTM 4 by the manufacturer (e.g. EXTRA Air). Please check this in advance. 

We recommend cleaning the rails after every ride and removing any dust or dirt from the wipers. In adverse conditions (mud or fine dust) or after a few days on the trail, it's helpful to apply a drop of suspension fork oil in front of and behind the Slider on the rails. Then compress the bike to work in the oil. Wipe off any remaining dirt once more. We've had good experience with R.S.P HyperWiper, for example. After that, your bike is ready for the next ride.

A 2.5-inch tire on a rim with a 30mm inner width fits in the rear triangle. Depending on the tire's actual size, a 2.6-inch tire may also be possible. This, of course, depends on the specific manufacturer. 

We have tested our storage box with a variety of tools. We recommend a maximum tool width of 3,2 cm. 

We recommend a pump as compact as possible with a maximum diameter of 25 mm and a maximum length of 21 cm. 

To ensure you're always prepared for emergencies on the go, our Storagebox has a dedicated pocket for tire levers and a tube. We recommend using a compact tube, such as the Aerothan by Schwalbe or a Tubolito. 

Das Extra Coil und Extra Air haben folgende Einstecktiefen:
S: 28 cm
M: 30 cm
L: 32 cm


Bitte beachte, dass der Aufbau der Vario-Sattelstützen kann im Bereich der Ansteuerung variieren kann und daher die Einstecktiefe durch die Stütze selbst noch leicht beeinflusst werden kann.

All shocks we specify for our mountain bikes are tuned in close collaboration with the respective suspension manufacturer and tailored to the bike’s kinematics. Due to our custom suspension layout, standard shock tunes often don’t work optimally and may limit the bike’s performance. For example, the compression tune might be too firm, or the rebound too slow. That’s why we strongly recommend using a shock we’ve specified – to ensure you get the most out of your bike and enjoy every second on the trail.

Yes, the Extra Air is UDH compatible.

For this Extra Air in 29" variant, a T-Type chain with 118 links is required. Setup is the same: 7th cog (21 teeth), key position A, for 32 and 34T chainrings. More info: https://axs.sram.com/guides/fullmount/chain/calculator
