Why a Combination Radius?

Ice skate runners come from the factory with what we call the "traditional" radius, which is one radius in the middle 2/3rds of the skate blade. This factory radius can be altered for performance gains by grinding a different radius onto the blade. While a custom traditional radius does result in performance gains over the factory radius, the  skate technician must often choose a single radius that matches the exact style, ability, position, and preferences of the player. Sometimes this can result in a loss of performance in one area of skating, when trying to improve another. For example, if you want more speed, you may lose some turning ability. This is usually OK, because the radius is tuned for your specific profile, however, wouldn't it be better if the skate technician could give you better performance for all maneuvers and all game situations without losing any performance? You bet! That's what a Combination Radius does. Also, goalies, don't feel left out, we have many combination radius specifically designed to improve your pivoting, maneuverability, pushes, slides and recoveries! Combination Radius are also called Compound Radius.

Combination Radius Explained

 

The dual combination radius is different than the traditional radius. If you look at the illustration above you'll see that it has two radius on the skate instead of one, a shorter radius in the front of the blade and a longer radius in the rear.  Because each part of the skate runner is used for different maneuvers, the combo radius will give better performance because no matter what part of the skate you are using, the blade is optimized for maximum performance for that maneuver, be it turns, speed, starts, strides, crossovers, backward pushes, ankle dekes, mohawks and more. With a combination radius you will be able to make moves that you never could before. Moves that will confuse your opponent, giving you that extra edge over the competition. In many skating situations, players will allow their body momentum to control their skating movements on the ice rather than the player controlling the skates. If you don't learn how to use your body in-sync with your skates, you'll never advance to the next level of skating. Players must "train" themselves to control body movements, create thrust, and to understand what is going on with the skates. A combination radius allows you to do this much easier than with a traditional radius.  "Watch the video at the bottom of page to see what we mean.

When we started offering combination radius, we were limited to the few choices the radius machine manufacturers had.  Most of these did make some improvements but they were designed with the old, "this one is for a forward, and this one for a defenseman" thinking of years past.  In addition, the difference between the front and rear radius were so small that the result  was like changing seats on the Titanic, it really doesn't gain you much.  We then started tinkering with different combinations, designing and manufacturing ones of our own and then testing them on a wide range of skaters to see what worked and what didn't.  This led to development of many different combinations, including expanding to Triples and Quads.  We've been keeping a database and recorded feedback from thousands of customers who are using our combo profiles and have used this feedback for our development process.  We pretty much have a combination radius that will work for every type skater.

 

Please, be wary of other shops or random people on online discussion boards who talk down combo's. It's likely they are doing this because they don't offer combos in their shop or they have never actually tried one themselves. If you simply talk with and watch someone skate with a combo, you'll find that very few would ever switch back to a traditional radius. The reason why is that the increased performance is amazing.

So, would you be willing to pay as little as $31.99 to skate better? That's all a combo radius costs. Much cheaper than camps, clinics, and power skating classes! Those are important yes, but nothing can improve skating more than a properly tuned skate blade. If you are serious about your game, a combination radius may just be for you. Here's an example of how a combo radius works ... let's say your skates have a single 9' radius. We can improve your turning by decreasing the front radius to 8', and also increase speed by increasing the rear radius to 10'. It's that simple!  Lastly, because combo's are especially suited for two-way play, if you play both Defense and Forward, it can work great for both positions. No more changing back and forth every time the coach changes your position.

Don't be scared to try a combo. For our new, first time customers, after you skate a few times on it, if there is something you don't like about the radius we selected for you we will gladly adjust it to a different combination or change it to a traditional radius for free. We give you a full 30-days to test it out. You have nothing to lose! We offer so many different combos, we are certain there is a right one to match your skating profile.

Triple and Quad Combination Radius Explained

 

In addition to our normal combos we also have great choices of Triple and Quad Progressive Radius. Our regular combos are great, most skaters won't need to advance to a Triple or Quad. However, there is an advantage to a "progressive" radius, which means the size of the radius's along the blade increase in smaller increments. For example, a 7,8,9,13' Quad vs a 7/13' dual.  Not everyone needs a Quad, but for many it offers a smoother fluid stride and seamless transitions.  We can also place extremely short and extremely long radius on specific portions of the blade where they will squeak out more performance but without having any negative effects.  Another example, a 6/13' combo would have great turning, but might rock forward too much and be a little unstable on some size skates.

 

 

Triple Combination Radius

 

We have two types of triples, first is a regular combination radius but it  also has a flat spot in between the forward and rear radius. This "flat" will increase speed quite a bit because no radius is faster than flat. It's also has great stability. These triple radius will result in just a little loss of turning, so it's best suited for up/down skaters who don't rely or use a lot of mobility. If you think this is you, ask us which triple we think might work for you. We also have 7 new progressive triple combos for all skaters (these don't have the flat area.)  These work similar to our Quads and also fit well on all junior and youth skates which don't have enough steel length to fit 4 radius.

What is Skate Pitch?

 

The Pitch of the blade is another very important part of how a skate feels and performs. When you get a custom radius, or a custom combination radius, the pitch settings can be adjusted. As you can see in the illustration above, pitch is the angle in which the blades lean toward the ice. It can be forward, neutral or reverse, and in varying amounts (in degrees or fractions of inches) For example a minor forward pitch would be .5 degrees or 1/64". A lot of factors are used to determine what proper pitch setting a skater should have. Pitch is critical because not only does it effect skating, but also body balance. If your balance is off, you'll have a poor stride. Pitch on the skates helps the knees unlock and to drop in the proper skating stance (90 degree knee bend with knees 2" forward of the skates.) In addition, if pitch is too far to the rear (a factory configuration for some model skates), you'll lose ability to accelerate. Believe it or not, the pitch of your skates also effects passing, shooting and checking. Pitch is one of the most critical components in equipment configurations. At No-Icing Sports, we'll customize the pitch along with your radius so you can achieve maximum performance in your entire game.

Quad Combination Radius

The QUAD is a combination radius similar to our regular combinations, however it consists of four fine-tuned and strategically placed radius to provide even more performance. These have been designed for each progressive stage of a skater's stride from push to toe snap.  Each radius on our QUADs are located and portioned on the proper part of the blade to achieve maximum performance and a smooth stride.

 

We still offer our 2 original quads, but those were designed mainly for the most experienced skaters. We now have a Quad for all levels of skaters from novice to expert. All our Quads have greater speed and agility than a stock radius and for many can offer more performance than our double and triple combos. Keep in mind that our dual and triples are significantly better than stock radius's as well but the Quads are just one step above those.

If interested in a Triple or Quad, please note such on your profile form when you fill it out.

Selecting Your Quad

 

Selecting your Quad is easy. Simply choose from the list above the Quad that most closely matches your position, style and experience range. For example, if you are an adult intermediate level skater who plays defense, the Quad 4 is best for 2-way play. If you're same type defenseman but want a tad bit more speed, the Quad 1 would be best for that.  The above list is a generic guide, keep in mind that there may be more than one of our Quads that will work for you, you aren't limited by what the list describes. If you want help choosing one, we can do that when we review your Skater profile Form.

If you'd like to see what kind of moves and agility are possible with a combo radius, watch this video of one of our long time customers, Will Graber. Granted as you will see, Will has great talent and personal drive, but the way his blades are profiled has allowed him to reach the highest level of skating skills possible. This video was made many years ago when will was in his teens. Will is now playing for Dartmouth College. Fast forward to time 2:40 to see Will's moves.

 New QUINT combo's are ready!

Our QUINT 5-radius combinations are in BETA testing but are avail to order for adventurist skaters who can't wait to try love something new. 

 

The name "quint" is derived from the Latin quinque-, meaning five, and for this radius it refers to the five functions that a Quint provides - Speed, Acceleration, Agility, Balance and Power.  A QUINT radius is a combination radius similar to our regular Quad combinations, however in addition to four properly sized fine-tuned radius, we've strategically placed a small flat gliding surface inside the Quad sequence to gain even more speed. Why did we do this, well, the majority of our customers are always asking for more speed.  But in order to get more speed, the radius have to be made larger and what that does is it can make the blades feel like skis. So to prevent that awkward feeling, we designed the Quint radius with a small gliding surface that will add more speed but which also has shorter radius on each side to eliminate that flat feel and maintaining maneuverability and control.

Right now we offer 3 Quints, the Quint Major (for size runners 254mm and up), the Quint Minor (for size 247mm and smaller), and the QUINTA, a special Quint for girls and women which compensates for the low center of balance (at hips) that women have.
