Inline Skating Knowledge: Rockering

I've been playing around with the setup of my skates recently, and decided to share my findings, to give people an idea what can be done with different wheel setups. All wheel sizes mentioned on this page are examples only, other sizes will work, too.

What is Rockering?

Most skates are sold with what we call a 'flat' setup, means: all wheels have the same size

This is a stable setup that suits most beginners and occasional rec skaters, providing good balance, speed stability, but limited manoeuvrability. This setup is easiest to control when practicing slides.

If you want more then you'll have to change some or all your wheels to different sizes!

Why the heck would I do this?

Simple answer: to change the way your skates behave in specific situations. To adapt them to your way of skating, to your uses for your skates. Skates you skate a Marathon in are not the same as skates you play hockey in, at least not if you have a choice. If you have the money buy a pair of skates for each activity you do on skates, and modify them to suit you and the activity perfectly. If you don't have the money (or storage space...) to do so learn to adopt your skates to your varying needs - and changing your wheel setup is one of the best ways of doing so!
On the financial side you can get maximum life from your wheels if you rotate them the right way into rockers (see explanation below), just in case you don't have to money to splash out for another full set of wheels for your flat setup every 2 or 3 months.

OK, so what can I do, and how does it work?

Well, let's have a look at the 'classic' rockering setups, and their pros. cons, and potential uses.
Let's start with a simple one: the 'HiLo' setup

Inline Skating Rollerblading Rockering HiLo

Benefits/Downsides: still quite good speed capabilities and speed stability (you sacrifice a tad at the top end), rotates a bit better. This position shifts your weight forwards, keeping you in a perpetual sprint position. This can be very comfortable, and can also be very helpful if you have problems with your weight shifting backwards resulting in backwards falls. This setup works well for slides, too, and allows extending the useful life of your wheels (see comment on wheel rotation below).

A bit more volatile: the 'front rocker'

Benefits/Downsides: you're rolling on either 3 or 2 wheels. This means that you have less directional stability at speed, a lower tolerance for speed wobble, but a better response to rotational movement. A very good trade-off if you, for example, would like to use the same setup for street and hockey skating.

One step further, the Full Monty: the 'full rocker' (aka Banana rocker)

Benefits/Downsides: a lot like the front rocker above, but more extreme - you're on 2 wheels at all times! This setup mimics an Ice Skate blade: inline skate rollerblade information rockering ice blade

This setup is mainly used for playing hockey, or for slalom; skating at higher speeds - and slides - become very hard to control. Frequently the wheel sizes are smaller than indicated here (I sometimes use 50-60-60-50) which provides a little bit more control (and less speed, which is not an issue here).

Why not do a bit of both? a 'full HiLo rocker' is the result!

Benefits/Downsides: Very similar to the full rocker above, but with your weight more forwards, which brings your ankles and knees into a more natural position and make intricate footwork easier. This is my preferred setup for slalom/freestyle, and it allows extended wheel use (see comment on wheel rotation below).

A specialist variant: the 'anti rocker' (aka inverse rocker):

This setup is only used in aggressive skating. It provides easier access to the frame (which provides less resistance and wears less) when grinding ledges & rails - frequently the inner wheels are either very hard, or are replaced with hard plastic blocks altogether, as they don't need to rotate at all. If used for rolling then this setup is very similar to a flat setup, but with higher wear on the two rolling wheels.

A few words of advice

rockered frames: some frames, especially for hockey skates, come in either pre-rockered configurations, or allow you to move single axles up/down, so you can create your own setups without using wheels with different sizes. Calculate the difference in axle height into your wheel arrangement, or you might end up with a very funny rocker indeed! ;-)
a special case of a pre-rockered (or not) frame is the Salomon FSK EA series:

The Salomon FSK EA frames don't have the axle holes on the same level - this is what Salomon calls a 'HiLo' setup, but which, in reality, is a flat setup with different wheel sizes.
If you want to create any of the setups above on this frame you have to subtract twice the axle height difference (2mm on these frames) from the 'normal' wheel size (think about it... radius vs diameter...:), e.g. the same proper HiLo from above requires 80-78-72-70 wheels now.

wheel sizes: the easiest way to get your hands on all the wheel sizes required is a shopping trip to your local, well-stocked skate shop (or, these days, your even-better-stocked online shop...) and buy a few sets in the right sizes. If this is a bit too expensive then you can do what I do - collect all your part-worn wheels in a bag, and once in a while measure them, and write the size of the wheel on the rubber (in such a way that, once the wheel wears down again, the marking is gone, too), and hey presto, you have a selection of wheel sizes to build different rockers from!
Both the HiLo rocker and the full HiLo rocker can be achieved by simply rotating your wheels the right way (that might be a reason why I love both these setups). A how-to can be found on the Wheel Rotation page, besides other information on this fascinating activity.
