SRB introduces a longer skate roller ski

The German manufacturer SRB now follows Norwegian IDT by introducing a longer skate roller ski in its product range. It is called SR07+ Skate-Premium and features a wheelbase of 700 mm; IDT Skate Elite Gold has a 715 mm wheelbase. The reason for this new SRB model is mainly the same as that of IDT’s:

Der SR07+ ist das neuste Modell in unserer Produktpalette. Er hat durch seinen verlängerten Achsabstand ein deutlich skiähnlicheres Laufverhalten. Aufgrund der verlängerten Frontpartie ist es möglich die Bindung in Balance zu bringen und somit den Beschwerden beim Umstieg auf den Ski im Herbst / Winter vorzubeugen.

It is noteworthy that it also mentions the possibility of balance point mounting of the bindings. However, with only 700 mm and fenders that take up considerable shaft length, I guess that one can’t use ski boot sizes bigger than EU 44 and still have the bindings at balance point.

Rollerski developer Tony Pölder

In the following YouTube video former Swedish national team cross-country skier Tony Pölder tells (in Swedish with his Dalecarlian dialect) his roller ski history as a user, developer and salesman. It is a very interesting account of a transformation period in the history of roller skis when the two-wheeled barrel-wheeled rollerski was invented.

Pole tip exchange systems

Sometimes one needs to exchange pole tips: when a tip is broken, damaged or worn out, or when the tips are not hardened or otherwise unsuitable for roller skiing. The old way of doing this is by heating the tip in hot water so the glue softens and pull the tip off the pole and replace it with a new one. In recent years easier systems have been introduced where heat and glue are not necessary, at least not every time.

Most of them use a screw mechanism where one either screws the actual tip onto an adapter glued to the pole end, or screws a nut around the pole shaft down onto (or into) the upper part of the tip. The brands using these mechanisms are 4KAAD, Fischer, KV+, Leki, Swix and Skigo. Two brands, Exel and Rex, use a quick lock system where a little tab in the pole tip holds on to a little ridge on the adapter.

Linked in the following names are demonstration videos of the systems by Fischer, KV+, Leki and Exel.

Interesting roller skis

Recently I visited the digital museum of Vest-Telemark in Norway and found the following interesting pair of roller skis named Truma Rollski that has the bindings not mounted directly onto the shafts but via a metal blade spring to the shaft at the front fork. I assume that this construction lets the roller skis lay flat on the ground also when the roller skier does the diagonal stride. It would be really interesting to try them out; I believe they require a special technique in e.g. step-turning. The levers above the front wheels are brake handles.

Has Woodski quit?

Woodski Incorporated is no longer available at Has its business closed or is the company just applying a retro strategy also in marketing?

Binding choice decides pivot point placement

On pre-drilled roller skis, like the new Swix Triac Carbon Classic, one can choose pivot point placement by using different binding brands and models without drilling new holes. This is so because different bindings use different screw hole placements in relation to the pivot point.

Swix Triac Carbon Classic shall not, according to Swix, be mounted with NIS bindings, and there are no pre-drilled holes for NIS or any other mounting plate system. The way to choose binding position is by selecting different screw mounted bindings. There are two sets of pre-drilled toe piece holes (the three holes stemming from NN-75 bindings) in Triac Carbon Classic. By using the two sets of holes and the bindings Rottefella Rollerski and Salomon Prolink, one can have the pivot point circa 10, 25, 35 or 50 mm behind balance point. Rottefella Rollerski gives the 10 and 35 mm options, and Salomon Prolink the ones at 25 and 50 mm. I would probably choose Rottefella Rollerski in the foremost position rendering the pivot point 10 mm behind balance point. I don’t see any advantages in the 35 and 50 mm positions, only disadvantages, so it is a little strange that Swix didn’t drill the holes 10 mm further fore, permitting a balance point mounting with Rottefella Rollerski.

Two new brands on Prolink bindings

Swiss companies KV+ and Tecnopro now market Prolink bindings with their own brand names on. KV+ has the Access and Pro models and Race Junior Skate; Tecnopro only Access. The bindings are probably made in Salomon’s Romanian factory that produces the regular Atomic and Salomon branded bindings. The model KV+ Prolink Race Junior Skate even has “Salomon” on the main sticker.

Fischer Turnamic Skiroller

This year, Fischer has launched its Turnamic roller ski binding called Turnamic Skiroller (like they say in German). It is just like Rottefella’s latest roller ski binding, Rottefella Rollerski, a screw mounted binding, a rugged construction that shall withstand the strain of roller skiing. Unlike Rottefella Rollerski it is a binding with two separate parts and 7 screws instead of 4. The screws have the Torx screw drive which is a little odd when considering the standard ISO 7794 that prescribes Pozidriv. The binding has also a new screw hole pattern not seen before.

Russian Roller Ski Brands

Yesterday I discovered on the Internet the Russian roller ski brand Klinsport so I wrote to the company for more information about it and for information about Russian roller ski brands in general. Klinsport’s director Vladimir Nikiforov answered and was very helpful so now I have been able to add eight Russian roller ski brands to my page Active Brands. Check them out!

Mounting Roller Ski Bindings

Since “mounting roller ski bindings” has been the top search on this site lately I think it is appropriate to write an article about that, i.e. mounting roller ski bindings.

According to me, roller ski bindings shall be mounted just like cross-country ski bindings, that means on or some centimeters behind balance point. This is so because the maneuverability is best in most situations that way. For the free style equipment the jaw of the binding should be on the balance point of the ski, and for the classic style equipment circa 1 or 2 centimeters behind.

When skating it is advantageous to have the ski level to the ground when it is lifted, and then landing flat when a new stride is beginning. In classic style skiing, and especially when doing the diagonal technique, it is advantageous to have the ski a little tip-heavy so the tip (or front wheel) of the ski easily stays in contact with the snow (or ground) and thereby is easier to direct.

However, many roller skis today are too short to allow for balance point or behind balance point mounting of the bindings if one has larger ski boots than EU 40. This is particularly so on skating roller skis where even EU 37 can be impossible to balance point mount without the heel colliding with the back wheel or its fender. On these roller skis one is often forced to mount the binding in front of the balance point making the roller ski tail-heavy when used. I think roller skis, just like skis, shall be adapted to the length of the skier and thereby also to the size of his or her ski boots, and this is also a principle I follow when building my roller skis.
