Kainpo RS frame set XC/DS 1-2
"Steel is Real"
The Kainpo RS frame has been developed for competitive use on the road and for dog races in the DS 1-2 class.
The same frame works in both sports, but the parts are selected according to the purpose of use and the user.
The frame is the result of many years of hard work, testing and experience.
The frame is handmade in Finland.
The manufacturing material is steel, which we have finally found to be a great material for a scooter;
-resistant to wear and bumps.
-suitably elastic, but still sufficiently rigid and durable with this frame solution.
-the most ecological of the frame materials.
-easily repairable.
- light enough
The unique design of the frame is protected as a model and there are no similar ones elsewhere.
This is an order product that is manufactured according to the customer's wishes. Among other things, the customer can choose the color himself.
"I inspect and finish each frame by myself to make sure everything works!"

Headtube
-The model-protected short main tube enables a low riding position.
-The short main tube is a very big factor that increases rollability and aerodynamics.
- Guide bearing dimensions: 1.5 – 1 1/8, ZS 44/55, semi-integrated.
Curved foot board
- Thanks to the long and curved stepboard, you can get into the most optimal landing position and get the center of gravity perfectly distributed.
- Enables different kicking techniques on different terrains.
- Saves the load on the support leg.
Reduces bottom contact with the ground, which is also a condition for good rolling.
-Allows a natural position for the foot of the supporting leg.
Integrated rear fork
-The integrated running board/rear fork without seams or joints makes the frame stiffer and more durable.
Mounting for a 12mm thru-axle in the rear fork.
-Fixing the rear wheel with a thru-axle makes the bike more stable.
-Thanks to the thru-axle, the rear fork does not have any protrusions that the foot bumps into.
-The rear wheel always sits straight and in line with the front wheel, which is also one of the most important prerequisites for good rolling.
Rear axle 12x100mm (1.5mm thread) Axle length 118mm.
Rear fork disc brake mount Flatmounth (FM) 140mm
-Flatmounth model rear brake bracket allows the use of all model brake calipers and all size (from 140mm) brake discs. (obviously requires an adapter suitable for each brake model and brake disc size)
Wheelbase
The long wheelbase significantly improves cornering properties.
-A long frame is a prerequisite for a "fast" driving position (when rolling and kicking)
-Thanks to the long frame and the curved stepboard, it is possible to use a 29" disc at the back and the device is still good for kicking without the calves and buttocks constantly touching the rear tire.
A "vertical pipe" consisting of three pipes
-Thanks to the three different tubes, the frame is vertically rigid, but also rigid laterally.
Foot board
-The aluminum foot board is replaceable.
-As an additional accessory, it is possible to install the teeth on the running board for e.g. mud weather.
-At the back of the step board is an aluminum so-called "support arc". using which it is easy to lighten the rear part of the bike with the help of the heel. The heel arch also prevents the heel from accidentally catching on the tire.
Roll and Aerodynamics:
In its shortness, good rollability and aerodynamics are enabled by a low main tube, a curved running board, a long wheelbase and the possibility of using a large rear wheel. On the other hand, it is also important that the front wheel and the rear wheel are straight and in the same line.
A "crooked frame", where the rear wheel and front wheel are not in the same line, is easy to make, but a frame where the wheels are straight and run in the same line requires a bit of special skills. - Kai Immonen
Solidity:
In addition to good rolling ability, riding skills and how hard you can ride the bike and dare to ride the difficult parts are equally important. Curve characteristics are very important. The long wheelbase of the Kainpo RS frame allows the use of a large 29" rear wheel without taking away the kick characteristics and that is a big advantage when you have to drive really hard in a corner.
Ground clearance/step height:
On a dog walker, the height/ground clearance of the step board should be optimized to such a height that the kicker does not have to focus on rocks and roots, but the bike can cross them without getting hit. Similarly, bottom contact should be avoided in soft and muddy conditions. They take away speed and the concentration on what the dog is doing is quickened. The slightly higher stepboard also gives you momentary use of more power for kicking. In dog competitions, the actual kicking periods are so short that you can kick them even from a slightly higher step! As a rule, you see scooters with too little ground clearance among dog racers, and this fact is also the reason for frequent falls.
"The harder, more relaxed and rolling you can move on the kickboard, the faster you will safely reach the finish line" -Kai Immonen
Frame weight:
The lightest possible frame is not necessarily the fastest option! A slightly heavier frame, optimal wheelbase and good controllability often guarantee better speed characteristics in bends and fast terrain. The ultralight frame is only useful for initial acceleration, but otherwise it might even be a disadvantage. Tests with speed cells have shown that the weight of the frame is not the determining factor for rollability, if all other things in the frame are optimized. Of course, the kicker must know how to utilize the features of the body as well. The weight of the kicker and discs (rotating masses), on the other hand, affect rollability much more than the weight of the frame itself. Weight builds up in the Kainpo RS frame also because the frame is longer than the basic kickboards and more reinforced.
"I claim that if the device is light enough for road races without a dog and can win World Championship medals with it, it is certainly light enough when the dogs are also helping" -Kai Immonen
Facts about kicking and kicking boards regarding DS 1-2 classes:
The most important equipment in the DS classes is of course the top dog if you want to do well in the competitions. The absence of a top dog cannot be replaced by a fast tool or your own hard kicking.
But when the dog is in good shape and the differences in the lead are small, then it is worth investing a little in the tool.
Kicking doesn't make sense even for a top kicker when you go over 34km/h! The basic kicker should not be kicked at speeds above 28 km/h. It only bothers the dog. Better to stay low in an aerodynamic position than to skid and rock back and forth. Every kick that is too slow for the speed eventually just causes the speed to slow down a bit.
The most important characteristics of a top skateboard are rolling, aerodynamics, stability and optimal ground clearance/board height. The development of the Kainpo RS frame has been focused on optimizing these features, and it has indeed been successful.
