フレームのスペックが各社微妙に違うので、自分に合うフレーム長やウィールとのバランスを考慮すると、組み合わせに悩む人が多いかもしれません。この場合、Pawerslide フレームの選び方と言った方が良いかもしれませんが、参考になる概論だと思います。

Frame advice by Yann Guyader

by JvS (Dec. 1, 2008)
With the multiplication and the evolution of the diameter of the wheels, it became the last couple of years really hard to choose the right type of frame, that fit perfectly with our needs and style. It can sometimes be a nightmare. Since the 84mm were unveiled worldwide in 2002, we got 3 more sizes of wheels, what also means new length of frames. With these changes becoming more and more usual, how to make the right choice when you go to the retailer to buy a new frame ?

Several things are required to make it right.
  1. The first and the most important is the wheel size that will fit into the frame.
  2. the second thing, is the length, as several framelengths are available for the same size of wheels.
  3. the last thing is the architecture of frame, soft, stiff or in between.
When you first buy a frame the first thing you have to do is to choose the diameter of the wheels that will go ijnto the frame. As a consequence you need to buy a frame that fits perfectly with your body, your skills and the way you intend use it.

  • For recreational skaters not really keen on hard training and beginners, I recommend to buy a frame of 12 inches long at maximum. This frame will allow a use of 90mm wheels ; which is the best compromise for recreational skating, moreover that kind of wheels give you the best feeling between roll, smoothness and agility A great option here is the Powerslide VENOM 12.0"

  • For people who want to skate a bit faster and do some regional races time to time a 12,8 frame with 100mm wheels is gonna be the best weapon for you. The Core XXX 12.8" should be your choice here.

  • And last, from people skating quite often and racing on a good level to the world class skaters, the 110mm frame is now the only weapon able to give you the ability to keep up and being competitive. XXX and ICON frames offer you all the possibilities you need.

    The only problem for you as a customer, is that the range of 110mm frames is becoming bigger and bigger, and it might make you be a bit lost when you get to the local retailer and this can become a nightmare when no one inthere is able to give you the proper advice.

    Here are the key informations to make the right choice:
    When you choose your frame, you need to find the one that is gonna fit the best with your body : tall or tiny, skating indoor, on tracks or road circuits, the length and the architecture of the frame that will fit with you is going vary a lot from skater to skater.
    Here are the different types of frame adapted to speedskaters according to your practice

    3X110-1X100 : this kind of frame, shorter and lower than a 4X110 frame is perfect for people looking for reactivity and agility. This frame is mainly made for track practicing, as it offers better cornering but this kind of frame is not only a track frame because we got the opportunity to see that this type of frame succeed in many marathon races especially in the WIC series where top class skater like Yann Guyader, Matteo Amabilli, Elio Cuncu, Kalon Dobbi and others won many top events on the ICON frame and on the XXX MEAN MACHINE. This frame is much more comfortable and allows you to keep skating smoothly even twhen you get tired. On the other hand it’s still the best combination for girls wherever they skate : indoor, track, road circuit or marathon…

    4X110 : this is the ultimate weapon for pure performance, some top skaters like Andres Munoz or Nelson Garzon, would never change their big frame with any other kind of shorter frame, its length allows a better push, more efficent to reach a top speed and gives you a better stability on high speed, what you can appreciate when you contest races like Engadin or Berlin. Do not forget that using that frame is not that easy and not everybody is able to do it. You need to skate perfectly because if you’re not smooth it may become a nightmare. Indeed, when you’re getting tired, you’re skating worse and worse and this frame is not going to help you to improve your skating style while being exhausted. This frame better fits tall people. This frame is indeed the ultimate weapon, but you need to be able to use it if you wanna buy it.

    After seeing all the different frame lengths adapted to each practice, you need to choose the stiffness of the frame you want to use : soft, stiff or in between.

    Soft or medium frames : they are adapted to people practicing track as they offer the best cornering and reinforce the grip of the wheel when the urethane is bending in the corner what gives you a better push. On the other hand this frame is more or less adapted to any kind of skaters, tall, small, light or heavy, beginner or top class skaters…

    Stiff frames : this is the best weapon for the power, it could make a comparison with a big chain ring on a bicyle. This is the better tool to reach the highest speed, but when you get tired… be careful because it could become a bit hard for your legs. This type of frame is adapted to tall, heavy or powerful skater but it’s also the best weapon for sprint races like the 200M.

    Choosing a Racing Frame for Your Skates

    Dec. 17, 2008
    "Frames may not be as pretty as boots, or as talked-about as wheels, but they are one of the most important components of your skate setup", says Peter Doucet at InlinePlanet.com

    "This was brought home to me last Summer while I was training in France before the World Championships. I switched to a stiff frame with a lower center of gravity (CadoMotus’ Pro Hilo 110) and suddenly cut my 200-meter flying lap time by as much as 1.7 seconds."

    In covering what is optimal in terms of:
    • Frame length for roll and control,
    • Stiffness and feel,
    • Frame height (that's easier on the shins); and,
    • Frame weight
    Peter, Canadian World Team member and owner/author of SpeedSkateWorld.com provides a plain-English guide to choosing the right frame for your inline speed skates that is easy-to-understand and cuts through technical terms and specifications to explain the differences between frames.

    Finding your optimal skate set-up

    (Dec. 26, 2008)
    In response to our story 104mm and 110mm wheels compared, a Pure Skating News reader this week asked:

    "If you had a 110mm hi-lo frame, would that put you in between a 4x110 and a 4x104 set-up in terms of acceleration and top end speed?"

    The top-end speed of these three skate configurations, in terms of wheel diameter rolling potential, can be thought of as:
    1. 4x110,
    2. HiLo (3x110,1x100); then,
    3. 4x104

    Frame Configuration Diagram


    Note that 'Wheel Size B' determines the minimum possible Deck Height (being that deck heights are set to allow clearance between the 2nd wheel and the lowest part of the forefoot) while maintaining anatomically-optimal pitch (angle between forefoot and rearfoot)

    However, skaters need to be mindful of the type of skating being done, for as wheel diameter (and rolling potential) increases so too does the skating speed required to take full advantage of it. If you're not regularly skating at those speeds, you could be needlessly carrying, pushing and accelerating too much skate hardware for the job – and limiting your own skating potential.

    The acceleration potential of any skate set-up depends on the type of skater you are, and the type of acceleration you want to optimize: from zero (standing), or from a rolling speed (and the speed range of that initial speed):
    • Skater size, strength and stroke rate
    • Type of acceleration (from zero, or speed-to-speed)
    • Typical skating speed range
    • Importance of economy (a single accelerative effort – like a 200-500m, or repeated intervals of acceleration – like a points, elimination, or perhaps marathon event)
    There are a number of factors that can be manipulated with skate configuration:

    Maneuverability (affected largely by frame length), Acceleration (wheel size & frame length), Top-end Speed (wheel size & frame length), and Stability & Economy (deck height) to name a few...

    A big, strong skater with a lower stroke rate can definitely achieve higher top-end speed using 4x110mm (a Mantia, for example). The lower stroke rate allows the 110 to roll out as well as overcome the turning resistance of the frame's length (smaller angles to track the skate through during the stroke, as more road-per-stroke is passing under the skate), and the lower turnover rate is not impeded by a 4x110 frame's higher decks.

    A smaller skater with a different technique (a Guyader, for example, making use of more frequent turnover) may use excessive energy trying to accelerate a 4x110 and not achieve the speeds they could (alone) on a HiLo skate, particularly in repeat situations. Without modifying his technique to match a particular skate type, this skater benefits from shorter frame length and lower decks, and a skate that can be accelerated more efficiently with less strength-per-stroke.

    Following the indications above, your individual size and skating style, as well as your target event types, should guide you as to the correct skate configuration to get the best performance out of yourself.
