Frequently Asked Questions

Gereral

Yes, this is possible, but you need at least one spacer. With a round spacer below the stem the cables can be mounted below the stem.

Please do not hesitate to ask us for that directly. We're trying to find an alternative for you.

Due to the current delivery situation, we don't always manage to weigh the complete bikes, as we are trying to get the bikes ready for shipment as fast as possible. But we're working on it ;)

As we're a young and small brand, our dealer network is still under construction, but growing fast. If you want to know if there's a dealer close to your place, please have a look at our website. We're updating it regularly.

In our showroom in Basel we have a test flew equipped with all of our bikes. As we know, that this might not be around the corner, we're also visiting selected events, such as the Bike Festival in Basel or the TestRide in Lenzerheide.
Or maybe the dealer next to your place has exactly the bike you're looking for.

Webshop

You can pay via credit card or you can make a pre payment. 

After receiving your order, we're collecting your frame from our warehouse. Then it will be assembled and finally packed. This procedure might take up to 10 days. 

Unfortunately this is not possible at the moment. 

Unfortunately this is not possible. If you're looking for a different product, please cancel your order and place a new one. 

Currently we have dealers in 16 different countries all over the world. If your country isn't represented, please get in touch. We will try to find a way to get your favorite ARC8 product to you. 

We're receiving new frames on a regular base. Please have a look on our website to a later date, maybe your desired frame is available at this point again. 

Extra Coil

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. 

On the EXTRA, we have introduced a new grease nipple. This allows for the expulsion of old grease and dirt while simultaneously providing fresh lubrication. The frequency of this grease change depends on the conditions. In very dusty or muddy environments, we recommend more frequent grease changes. If the slider feels stiff, a grease change is also advisable. However, an annual service is recommended. We suggest using suspension grease such as Sram Butter or SlickKick. 

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. 

Essential

It covers well what people call trail or all mountain. But it doesn't mind an occasional XC or enduro race. 

The Essentialis designed to be used with short stems. We recommend stems that are 35 to 55 mm long. 

In general you can mount any 4-piston brake, if it is a flatmount brake. As far as we know, there is only one supplier offering a 4-piston fatmount version. Unfortunately at this point there is no adapter solution which solves this. 

The Essential was developed and tested for a maximum system weight (rider, bike, riding gear) of 110 kg. 

Evolve FS

We planned to do the Evolve FS in three sizes, S/M/L. But then something very confusing happened: we received the first sample in M size, and riders from 1.60 to 1.80 all seemed to fit perfectly on that bike. Trying to understand it gave us some sleepless nights. Lots of measurements were taken, photos and geometries analyzed. Finally we brought the bike to Andreas Gösele, doctor of the Swiss Olympic team and a well known bike fitting expert. As it turned out, we created a highly adaptable geometry, and an S size is simply not needed. 

Whether you classify the Evolve FS as a cross-country or a down-country bike is up to you. What's important to us is that it's just incredibly fun – both uphill and downhill.
Modern cross-country race courses demand a lot from riders and equipment. That's why the Evolve FS underwent rigorous testing by the EFBE Institute and was cleared for ASTM 3.

The Evolve FS is designed to be used with shorter stems than what usual is used in XC. We recommend stems that are 35 to 70 mm long. 

There is an important relationship between head tube angle and stem length. A steeper head tube angle makes for a faster, sometimes twitchy steering, while a slacker head tube angle feels more controlled, but needs more rider input. A longer stem on the other hand will slow down the steering and make that steep head tube angle more controlled, while a short stem will create a more direct feeling and speed up steering. So a short stem with a slack head tube angle will feel somewhat similar in terms of steering like a long stem with a steep head tube angle, but it places you further behind the front wheel, putting you in a better position to attack steep descents with confidence. 

The Evolve FS is available in the Fox Factory version with a remote option. However, the variant with Fox Performance suspension components is unfortunately not available with a remote optio

Fortunately, we were on-site and were able to take over the defective frame directly and provide the rider with a new one. From then everything ran at full speed for us because we wanted to know exactly what had happened here.
We tested frames until they failed, deliberately damaged frames, and tested them again, but we could not reproduce this scenario. The reliability of our products is extremely important to us, which is why we decided to revise the layup of the Evolve FS again to be on the safe side.
The Evolve FS was then tested in addition to the intensive tests at the manufacturer also at the EFBE Institute and passed the test bench tests for ASTM 3 and even exceeded them significantly.

Escapee DB

Tire clearance varies with the rim width. Please make sure, that the effective tire width is not any bigger than 30mm. 

The Escapee is designed and tested for a maximum total weight (rider plus bike plus equipment) of 110 kg. 

Generally we mount a 52/36 crank. If you desire another size, please contact us - usually we can offer you an alternative option.
