Frequently Asked Questions

If you have a question regarding your Marwes, you have come to the right place! Here you will find answers to the most common questions asked from us since 1986. If you can’t find the correct wisdom  here, contact us by using this form

What are the main differences between Marwe Aluminium and XC Composite roller skis ?

In general, the main difference is in skiing feel.

  • In the Aluminium skis, the frame is a bit lighter but also stiffer
  • The Composite roller skis frame is close to a normal cross-country ski in construction, so it is more like skiing on snow

For example, most of our national team skiers and other snow athletes (Biathlon, Nordic Combined etc) use the composite XC-skis for training. Some heavier skiers, and sprint skiers, like the aluminium ski because it suits them and their training better.

Can I get new wheels for my old Marwe´s?

Yes. All of our roller skis are downward-compatible. This means in our case that you can use our current roller ski wheel range, but you might have to you use spacers or other adaptors to get them to fit.

Is there a recommendation as to the torque with which the screws should be tightened when changing the wheels?

There is no specific torque for the bolts:
– Free rotating wheels need to be tightened so that there is no freeplay in the wheels
Nyloc nuts will ensure that the wheel will not get loose
– Ratchet wheel needs to be tighter, so that it does not slip backwards. This is why we use
hard 10.9 bolts and nuts in the skis (Std bolts are 8.8)

One of my XC roller ski frames broke. Can I get a replacement frame for it?

The short answer is yes. At Marwe we emphasise our athletes to be environmentally aware. However, in the case of the composite XC ski range, we strongly recommend changing both ski frames in case of one of the frames breaking down. The reason for this is that the XC ski range ski frames are tested for their flexibility at our factory and paired together so that both skis have similar vibration damping and flexibility characteristics.

What is the difference between the MEDIUM and STIFF XC ski model frames?

The stiff frame is designed for skiers who weigh over 90 kg, or whose skiing technique is of a more powerful kind. This frame has been made to be an option based on feedback that the medium stiffness,  long classic XC-frame is too flexible for some bigger athletes. For example the Marwe CLASSIC 700 XC roller ski frame.

Also, we have discovered that for example, our own Finnish national team skiers prefer to use the stiffer frame even if they are not this heavy, as they put a much bigger stress on the skis than normal weekend skiers.

How do I attach or detach the support struts on my 800XC roller skis ?

Is it normal that the front ratchet wheel on Marwe Classic roller skis spins slower than the rear wheel when you spin them with your hand?

It is normal that the ratchet front wheels might have a bit more friction than the rear wheel but when you ski with the rollerskis this should have no effect on the speed of the skis.

Speed of the wheels depends mostly on the elasticity of the wheel material, and the bearings don´t have much effect in this.

How do Marwes roller ski wheel speeds correspond to Swenors designation on rollerski wheel speed?

  1. USR is a racing wheel, very fast and made with a different manufacturing process than the training wheels
  2. US0 is fast training wheel
  3. US6 is medium speed wheel, Swenor 2 is about the same speed as this
  4. US7 is a slow wheel
  5. US8 is a very slow wheel

How can I ensure that my wheels wear evenly and get the most out of them?

During your roller skiing exercise, we strongly recommend swapping your skis at the midway point. Doing so you will ensure even wear of the wheels and they will last longer. This will prevent the excessive one-sided wear of the wheels, and avoid the ski tracking to one side.

How do classical and skating style roller ski wheels differ?

Roller ski wheels differ quite a bit depending on the chosen skiing style.

The first thing to consider when buying wheels for roller ski are the style. For roller skis, there are two styles.

  • Classic style where you move your legs in a parallel movement
  • Skate style where you move your legs similar to the way you would be moving on
    inline skates, putting the feet’s in a fishbone position

Classic style roller ski wheels are wide and made for rolling in the middle of the wheel. Skate wheels are narrower and made in a way, where there is a smoother transition from side edge to side edge.
