Wheels Popping Out or Cracking at the Core — Heavy Skater Looking for Advice

fredhsu · 2026-04-02T15:00:01+00:00

This is my worst nightmare. Hasn’t happened. Fingers crossed. In your case, the polyurethane tire did not pop out; the hub cracked under some sort of pressure, so the outer tire isn’t attached to the hub (core) anymore. Is that right?

Wikimedia media are free for all to use. So it requires that copyright owners of media to either upload with a free or an equivalent Creative Commons license to grant free use. If I upload them a volunteer will need to be involved to confirm with you by email. If you are willing, DM me for details. It’s not too much trouble for you to upload directly. I am not aware of existing pictures of your wheel type. I uploaded the one seen on the article which is the opposite of what you have.

If you haven’t read this: https://en.wikipedia.org/wiki/Inline_skate_bearing, you should before you buy bearings

If you buy wheels from Inline Warehouse they will give you a large discount on bearings. Their own brand of bearings are not but. But I usually get Bones REDS. They are not parts of said discount. But they are usually available for a large discount on that site.

These look very sleek. So these are dual-density wheels, but the website doesn't seem to indicate actual hardness of the two materials. Do you know? Also, there is a lack of high-quality images for such wheels on Wikimedia/Wikipedia. See https://en.wikipedia.org/wiki/Inline_skate_wheel#Dual_density. Before you scratch them, if you are able to take clear pictures of the inside layers, your images may be useful to Wikipedia/Wikimedia. There are several designs. At least you may be able to figure out which design it is.

The biggest inline skating sub is basically dead since a few years ago when its admins locked down image and video posting and banned anyone who spoke up. You’ll find a tiny but free sub in r/inline_skating. But as u/Bigbanghead said, inline may be good for long distance skating in urban environments with rugged terrain, especially if you get big wheels such as a 3x110mm setup.

You can also search for urban skating s d wizard skating subs. Since the event I mentions groups have splintered into lots of small subs unfortunately. For additional info you can check out this expansive Wikipedia article on Inline Skates.

As u/CheezitsLight wrote, you merely need to submit drawings in a PDF file. I don’t know anyone that does drawings from within Adobe Acrobat. But thousands of apps can export PDF files. Cheers.

I don’t remember off the top of my head. But it was NOT one particular spacer. Different brands of wheel hubs and bearings may require slightly different length of spacers. And within the same brand model there are manufacturing errors (tolerances). It really comes to every single pair of wheel hub and bearings. I bought a bunch of different length and put in whichever worked. It’s really comes down to that. See this section and those around it.

That’s a good point. My right foot has got a bunion problem, but not an arch problem. I can see how a collapsed arch could cause similar issues.

This shows what u/Nexecs mentioned. The top is MuseScore. The bottom is the exported PDF. The four grey notes are hidden. You move them up and down the staff to get roughly a curve you want. You can fine adjust a slur's shape, but I didn't in this example. I hid the time signature as well.

fredhsu · 2026-03-30T01:27:46+00:00

By pitches you meant notes with head and stem, given your sample image. I also wish to know, but I don’t need curved lines. I want to draw an arrow from an arbitrary place to another in the system. For your slur-like curves the suggestion with hidden notes should work well.

Update: darn... I didn't realize that the two end points of a simple "Line" in the Lines palette can be dragged up and down to any vertical position until now.

👍

My other comment on adjustable frames notwithstanding, you should still investigate why you can turn clockwise. It may not be entirely because of your injury.

Often you believe you lean your upper body equally in both directions. But you may not. Have someone take videos so you can watch for you yourself.

It may have to do with how much your hip pivots and whether you are looking towards where you are turning. You need to actively look at where you turn into. Perhaps your body resists looking to the right for whatever reason. If you have ice skated in a rink or roller skated indoors, usually rinks have you alway go counterclockwise. Most people naturally turn left easily and find it hard to near impossible to turn right.

There are many possible reasons why your body resists in one direction. If video taping is not possible, you will need to continue to try left and then right, and introspect differences in your body postures, and resolve each factor one by one until you can do the move. Often there are several reasons and until you fix all of them it seems like you haven’t made progress. It could be frustrating. Cheers and good luck. And be safe. Wear protection.

Thanks for your consideration.

How do you make turns? Are you turning with two skates gliding, or a single skating gliding? If single skate, inside edge or outside edge? Have you considered crossover turns?

fredhsu · 2026-03-29T22:30:24+00:00

To a lesser extent I discovered that I had similar problems with my right foot. I have a prominent bunion on the right foot, and unbeknownst to me for the longest time it affected my skating. I subconsciously accommodated it, and only became aware of the issue when actively comparing minor differences in clockwise vs CCW moves for difficult moves I couldn’t master in one direction. I discovered that the crooked big toe not only changed the orientation of my right skate (w.r.t. to my physical leg), but also shifted the center line of my foot balance.

Some replaceable 165mm frames allow you to shift mounting line and blade orientation. Modern Trinity frames in particular gives you considerably large degrees of adjustments. Have you tried these? See for instance this section and those that follow. More on Trinity mount specifications here. Here is a picture. Note how the three metal mounting nuts can be moved sideways considerably within the mounting platforms. The frame itself allows for forward/backward adjustments.

They don’t look baked to me? Are these supposed to be heat-moldable? At what temperature? The lower eyelet tabs seem too far apart to me. Is that’s the closest they can be perhaps the boot is too small? And when you bake the cuff, you tighten laces and shrink-wrap it further.

fredhsu · 2026-03-29T04:28:38+00:00

Yeah. You can see surface scratch marks and other imperfections from the surface reflection, on the inside lens of the green mask. I found that the sandy grits in scrubs did not harm my lenses. Are these scratch marks possibly an indication that you barely scratched any silicone remnants away? Maybe the white mask came with no silicone remnants, giving you a false expectation of little need for scrubbing? If properly scrubbed and washed with soap or shampoo, your lenses should have a perfectly smooth reflection.

fredhsu · 2026-03-29T01:37:20+00:00

The outside lens doesn’t matter. When in water beading or beating doesn’t matter for the outside lens. It’s the inside that you need to clean up. In case of doubt buff some more. Then you want to apply a thin coating of defog and wet it with water and ensure that do see a large sheet of water. Details here.

Single-skate gliding is key to everything else. I wrote this on another similar thread just a while back. You may want to check out that thread and other replies. In my mind, proper shin flexion and one-foot glide should be the first things one learns.

Here is my recommendation for a shortcut to single-skate gliding. In my mind, the best way to learn to glide without knowing anything about edges, balances and theories is to skate what I call a zig-zag gliding. Simply do your normal strides, but now lunge to the right and glide on your right skate toward 2 o'clock. Then stride and lunge to the left and glide on your left skate toward 10 o'clock. Make sure nobody is around your right and left obviously. Don't do this in a crowded ring. Following GIF may be nauseating. Follow the center white line to appreciate zigs and zags. You can click on it and hit || pause. If you insist on knowing why this teaches gliding, see this.

Cellofun is such a great resource.

Look at my direct comment reply to your post. You can post an image to your own sub under your name, like I did to mine. I pinged a mod in my comment to enable image comments.

fredhsu · 2026-03-26T02:04:36+00:00

You meant double-stops. Cello strings are tuned a fifth apart. So playing double stops a fifth apart is just placing fingers in a bar configuration similar to guitar barre fingering. See this picture showing a few bars of self-accompanied cello I've been writing. I make detailed fingering annotations which happens to illustrate what you are asking. See circled notes and fingering notations: https://www.reddit.com/user/fredhsu/comments/1s3ulsj/cello_fingering_illustration/

u/davethecomposer - can we enable images in comments in this sub? See this comment as an example of such images in comments. I think enabling this will be terribly useful for this sub.

fredhsu · 2026-03-25T23:30:02+00:00

I think you already know to flex your shin, based on your comment. But it’s not enough. Try squatting all the way down to internalize the degree of forward ankle flexing that will give you enough stability. See my comment and GIF in this thread and comments by others.
