How They Work:

  • There are two different types of roller skis: Classic and Skate; just like cross country skis. 
  • The "Body":
    • A typical roller ski has two main parts: the ski and the wheels. The skis are about 1 1/2  to 2 feet long, in the middle they have a binding mounted onto them so you can put your ski boots on them. These are the same bindings you can use for cross country skis.

  • The "Wheels":
    • The wheels are different for the technique you are doing. For skate, they have a larger diameter and are skinnier. And for classic they have a small diameter and are wider. The classic skis have a ratchet on the back wheel so you can ski up hills; this is a reflection of kick wax; but the ratchet is mostly more reliable than kick wax ever is.
  • Poles (get a six pack):
    • Unless you want the biggest legs in town, you also typically use poles so your upper body can do some of the work as well. The skate poles typically are the height up to your mouth/nose, and the classic poles are the height to your armpit rang. For pavement you will want to put roller ski tips on, they will last longer because they are built for hard surfaces; and will grab the pavement better.
  • Typically the best places to roller ski are on paved roads and bike paths, they do not work on gravel due to a high force of friction.
