These wheels come in 38mm Width/62mm Height for indoor skating, so they are a  relatively  narrow wheel.  I wore these wheels for about 3 months, 2 seasons ago thinking I was getting the old version of them when I ordered.  I was surprised with a newer version of a wheel that I did not want changed.  They were great for speed and juking around the track, and for stopping.   (The old version came in a darker Forest Green as opposed to Kelly Green).  I loved the old Green Omegas:  They really were the perfect wheel for me.  As a skater, I tend to skate on my toes, and on the front two wheels of my skates.  I like to accelerate quickly through sprinting, and not use long strides as much.  With the changes, the wheel just wasn’t the same.

What I didn’t like about the changes was that the wheel seemed to wear out more quickly, not be as fast and much less solid in the center of the wheel.  For instance, the “new” omegas have a nylon hub, while the old ones had a hollow core.  The old ones are more like the Atom Lowboys, which I really like, and the news ones, are just like an unwanted relative who annoys you.   With the Nylon hub, it feels like there is too much give or spring when I skate, and therefore, it takes away from speed as I am pushing, yet my energy is going into the Nylon as opposed to into the floor.  Plus, they do not feel as hard as the old ones, yet I can not find the data on the old ones, so I can’t really say if they were perhaps a 95A unlike these that are 93A.

It’s important to note that if pricing lends to quality and performance, (you get what you pay for saying), the Atom Omegas 93A Green are approximately $40 cheaper (list price) than the Lowboys.  So, if you are on a budget, and you are an agile skater, then you might prefer to wear the Omegas.

My request to Atom, bring back the old Omegas.  They were far superior.  Just this gals’ opinion.  However, as an afterthought, given the prevalence of scrum starts, who needs to roll as much?  It’s become more of a game of lateral agility, and they are quite food for this.

P.S.  I dug up an old set of Green Omegas, and I am skating on them now.  I begged someone for them, and since it’s hotter and more humid out, and we skate on wood; they feel like new.  If I were skating on concrete or skate court, I would not be wearing them though.  They are better suited for wood and polished concrete.

Sure-Grip Avenger in White:

Before I start the actual review, let me spell out what I think makes for an awesome derby plate:  Durability, agility, maneuverability and roll performance, stopping performance, lightweight, speed and precision.

I want to be able to turn on a dime, and at the same time be able to roll like mad on hard wheels and not have my ankles and legs weighted down by heavy plates.  Of course, I want the plates to last and not break down on top of the rest.

I currently have two sets of white Avengers, a set on my Vanilla Boots and a set on my Riedell 951s.  They are both set up short forward mount.  The Avenger in white has a new DA45 truck, which is slimmer than the original version and optimized for this with the fixed king pin in the Avenger.

Onto the review….

From my perspective, the Sure-Grip Avengers with the DA45 action meet my requirements across the board.

First, let’s look at durability. For those who are nervous about the strength of the Avenger and subscribe to the idea that if it’s lighter, it has more potential to snap or break mid-jam, odn’t worry.  I weigh more than the average skater (most likely) and I practice sometimes 6 times per week.  I have had  no breakdown with this plate since I started skating a prototype in October 2011.  So, Durability, check!

Next, agility, maneuverability and roll performance since they are all intertwined.  Wait…How is roll something to which the plate contributes?  Read on….

There is no skate action better balanced for derby than a DA45.  It can be tuned with various cushions to go from silly-loose as to be uncontrollable or so tight they will not steer.  So, that leaves a lot of tuning room in between.  Don’t get me wrong, any skate can be tuned in a similar manner, yet that is where the DA45 geometry steps to the front.  For any given state of adjustment the DA45 will turn easier and sharper, faster than anything else out there.   On scale of 1-10, you can get any skate to turn into the 6-7 range, although some take more work than others.  The DA45 goes to 10 due to the unique combination of the “45 degree” king pin angle, the precious adjustable pivot and of course the double action cushion arrangement.   The geometry also lets the wheels stay flat on the floor longer than other designs.  This improves traction, which means you can generally run harder wheels.  That’s where roll comes in.

Want a short forward mount?  This plate is perfect for that, and Sure-Grip even writes “your plate will not hang over the front of your boot”, which lets the place be mounted further forward into the derby sweet spot.  This leads to more agility, better maneuverability and roll performance, all there in spades, check!

What makes them so light?  The white Avenger plates are made of magnesium alloy and feature a holl0w center.  The kingpin is hollow as well.  Both of these features were designed to save weight, which translates into less fatigue on your feet, easier pushing and overall lightness.  There are lighter plates out there, but they are plastic.  They bend and twist which costs the skater performance and there is always the possibility of a plastic plate breaking.  It’s lightweight and with none of the disadvantages of most plastic plates.  Check!

Speed, you will certainly have that as well with the Avenger.  The sleek design lends to less air over surface friction, and therefore, less drag, more speed.  You can focus on working smarter, not harder.  Riding on these plates reminds me of driving an expensive BMW, the handling is supreme, and pick up is unsurpassed.  The plate does a remarkable job of sending energy to the front or back, which allows for your wheels to meet the needs of the jam at hand, whether it be quick pick up speed or long strides.  Speed and Precision, check!

These plates have made turning, hockey stopping, snowplowing and powersliding so much easier.  They make juking and running on your skates feel like you are running on air.  So, Stopping, check!

The Avenger in white is starting to take off in my league with skaters  replacing their old DA45 Magnums or what not, and newer skaters getting them on their first set up.  The feedback is pretty awesome.  Never before have I heard so many positive comments about a skate plate!  personally, they have revolutionized my skating, and I can not recommend them more.

This plate runs $191 MSRP.  You can find them on various derby websites and www.suregrip.com.  If you have more questions about “how the (white) Avengers work”, then just check out the website above.

This is going to be the summer of roller derby documentaries. We can add Hell or High Water to our list of derbumentaries. The trailer doesn’t give much info behind the story of the film but here’s what their site says.

This inspirational story follows the Nashville Rollergirls through the loss of their practice space, the move to a new game venue, injuries, relocation of key players, huge financial pressures, and even an epic flood.

Ever the underdog, and with a burning in their bellies, the Nashville Rollergirls seek to prove themselves at every turn. And nothing will prevent them from achieving the goals they set.

On a quest to succeed athletically on the national stage, and to keep their skater-owned and operated organization afloat, the Nashville Rollergirls, in true Nashville spirit, refuse to accept ‘no’, ‘can’t', or ‘won’t’. And in true roller derby spirit, they bring ‘do-it-yourself’ to the next level.

Jam Expectancy Study: Power Jams

In both the introduction and situations posts, we’ve talked about expectancy on a jam-by-jam basis.  We’ve counted one absent blocker at the double whistle as a -1 toward the iPS.  It’s a decent way of measuring the cost of blocker penalties because the beginning of the jam is when pack strength matters the most.
Jammer penalties, on the other hand, are a completely different beast.  Whenever a jammer is in the penalty box, it’s a very … Continue reading »

Jam Expectancy Study: Pack Situations

If you read our introduction article posted last week, you should now have a pretty good understanding of the concept of expectancy and how it might apply to roller derby.  We’re trying to determine what results, on average, a team can expect in different situations.
At the beginning of a jam, each team lines up with 1-4 blockers between the pivot and jammer lines.  The number of blockers each team has as of the double-whistle is … Continue reading »

Sure-Grip - Super Cushions

In my opinion the best value for your dollar upgrade is usually replacing your stock cushions. The Sure-Grip Super Cushions are similar to their Powerdyne cousin the Magic Cushions in style but not in price. I’ve heard great things about these but not sure what plates they will work on. If you use these and have an opinion please let your fellow skaters know.

Jam Expectancy Study: Introduction

The essence of roller derby is 5 skaters on each team: 1 jammer who must get through a pack of blockers, and 4 blockers who must both aid their own jammer and impede the opponent’s.  At the beginning of every bout, these 10 skaters line up on the track.  The odds are even, and each team has to account for the same number of opposing skaters.  This is always true in the first jam, but it’s … Continue reading »

Evolution of Jam Starts - Fall 2010

Back in 2010 I took footage at the WFTDA Eastern Regionals for the purpose of studying and teaching jam starts. Coming out of the Championships of 2009, it seemed pretty clear that those 30 seconds before the whistle and positioning after the whistle was going to be the next big evolution in the game after general speed regulation.
Since I posted the video, I’ve been teaching the concepts around those 10 starts I published on YouTube … Continue reading »
