Go to an outdoor basketball court, and chances are you’ll be looking at thick, durable rims. Look a little closer and you’ll see what looks like two single rims stacked on top of each other.
This is quite different from the thinner variety used for most indoor wood tile courts, known as single-edge hoops.
There’s a good chance you’ve heard people complain about double-rimmed hoops. It might make you wonder, why do some basketball hoops even have double rims. Are there advantages to using double rims instead of single-rim hoops? Let’s take a closer look.
What is a double-rim basketball hoop?
Before we go any further, let’s define what a double-rim basketball hoop is.
A double rim is a type of basketball hoop rim made of two single rims stacked on top of each other. This is in contrast to most basketball hoops or baskets which only have a single rim, a round piece of metal about ⅝ of an inch thick.
The double edge is slightly thicker and longer than the single edge, about twice its thickness.
please note Many rims, including those used by the NBA since 2009, look like double rims but are actually single rims with a tubular binding system. The tube under the rim is thinner than the rim and is used to tie the net more neatly instead of having hooks sticking out.
What is the purpose of a double-rim hoop?
There is one definite purpose of a double-edged hoop: durability. Hoops with double rims usually last longer than single rims.
In many communities and recreation centers, double-frame hoops are deliberately chosen so that they can get more “miles” out of the basketball hoop. These places have fewer resources to maintain the court and are more likely to deal with misconduct, so a double edge becomes a logical choice.
If the basketball court is located outside, there is all the more reason to use double-frame hoops.
Natural elements such as rain and snow can cause wear and tear. Dunking and hanging on the rim wears down a basketball hoop over time, so if there are a lot of high flyers in the area, a double rim will last longer. Double rims lend themselves better to ferocious dunks and other extreme play.
In short, not only will they last longer, they can save you money in the long run.
Single edge vs Double edge: Which do players prefer?
The choice between single and double rims has been a constant point of contention among basketball players.
The vast majority of players agree that a single rim is better for playing basketball. A double edge’s extra thickness creates angles that make the ball bounce rather than go through the basket. As a result, making shots on double-rimmed basketball hoops is more challenging.
Because a single rim allows for more rolls and lucky bounces than double rims, shooters generally prefer single-rim hoops.
However, there is an argument for preferring double-edged hoops as well. Since a double rim makes it more difficult to shoot, it can force a basketball player to improve their shooting ability, such as shooting with a higher arc and with better shooting form.
Basically, a standard edge is more forgiving and fun to play with, but playing on a double edge can improve shooting habits and reward good shooters.
Dual rims tend to be “difficult”.
A common misconception is that the extra thickness makes a double edge less fun to play on.
But often it doesn’t actually have to do with the actual edge itself, but rather, how tightly the rim is attached to the backboard.
Basketball players often talk about how ‘hard’ or ‘soft’ a rim is. Softer rims are more flexible and give more. This can make it easier for shots and rebounds to not bounce as far and land too far from the hoop. Meanwhile, hard rims are tight and the ball will bounce off the rim with greater speed.
The problem with dual rims that people forget is that they are often bolted directly into the backplate. However, higher-end rims have more refined attachments that take pressure off the target, giving them that softer bounce. Breakaway rims even have springs that give them even more flexibility.
The point of all this is that it’s not necessarily the extra thickness that makes a double edge less fun to play on. Rather, it’s the fact that they’re usually attached very firmly to the backboard, which gives them a harder bounce.
Does the NBA use dual rims?
The NBA does not use dual rims, but instead a modified single edge with a “tube-tie netting system” designed to prevent players’ fingers from catching the hooks found on old rims. This tube tie netting system gives it a similar look to a double-edge hoop, but the edge is NOT the same as the dreaded ‘want it or miss it’ outside double rims.
The league first introduced this new rim design for the 2009-10 season, replacing the previous rim design with protruding net hooks. The new design is safer, and despite being slightly thicker, it didn’t affect field goal or free throw shooting percentages.
Do street basketball competitions use double rims?
Given the outdoor nature of street basketball, you can expect them to have double-edged basketball hoops that can withstand tougher conditions and outdoor elements.
However, official FIBA 3×3 or Nike 3-on-3 competitions use standard rims like the NBA. Of course, neighborhood pickups and the like will use any hoop available.
So, do rims really matter?
If you play basketball, this shouldn’t even be a question. Of course it does!
Unbeknownst to many, basketball is as much a mental sport as it is a physical one. Even simple quirks can affect the flow of the game, much less a critical one like the hoop!
So how does a rim’s makeup change certain parts of the game? Let’s talk about rebounding first. Anyone in basketball knows that rebounding is an essential ingredient to victory. “The team that controls the rebounds controls the game.”
An edge’s composition can inherently affect the bounce of the ball and therefore can affect recoil. A “soft” rim (like most single rims) doesn’t allow for long bounces from fog and favors the bigger guys patrolling the paint.
On the other hand, like most double rims, a “hard” edge makes the ball bounce faster and harder. This allows long rebounds and negates the benefits of a longer span.
Unless you play professionally, it’s not your business to dabble with the fringe material in your community. You will have to learn to adjust how to play on a single or double edge. As you watch the first few plays, figure out how the ball bounces off the rim and adjust accordingly.
A double-rimmed hoop is a type of rim that has two rims stacked on top of each other. This is a common type of basketball hoop found on outdoor courts and recreation centers. Durability and the ability to withstand abuse are the reasons it exists.
If you are a beginner trying to improve your basketball shooting skills, practicing on a double-rim basketball hoop can be helpful. But unless you have plans to become the NBA’s next great sharpshooter, practicing on a standard rim with a softer rebound will better prepare you for school, college or competitive street ball games.
