K2 r100 UFS 100mm Inline Skate Frame - REVIEW

These are the K2 r100 Frames. They run around $99 US. They’re machined out of extruded aluminum which makes them extremely solid. They’re UFS and are designed to fit four 100mm wheels.

The metal frame spacers can be rotated 6 directions to create your perfect setup. I ended up banana rockering them, which means the middle wheels are down and the outside wheels are up. This should make them easier to turn than having all 4 wheels flat.

I set them up with some Undercover Mushroom Blading wheels and some Rollerblade SG9 bearings on my Seba CJ skates. I had a bit of trouble getting them set up until I realized half the frame spacers were different. 

The axles are designed to allow for a single tool to tighten, which means the frame spacers need to be installed a specific way. This is great design after I realized what was happening, but wasn’t super intuitive.

I skated them in my neighborhood to see how they feel.

Over the next few months I skated them on different terrain. I got pretty confident with some of the flatland tricks and was able to parallel slide better than ever.

I love skating the K2 r100. They’re similar to the feeling I get with my 3 by 110 triskates but with a better wheelbase for landing gaps and doing turns.

Are the K2 r100 the must have frame? Most likely not.

The r100 are long. Really long. Even with the rocker making turning easier, they’re too long for me to comfortably skate without clipping my wheels. I sometimes feel like I’m wearing clown shoes, there’s just too much wheel for me.

They’re UFS, which means mostly aggressive boots will work. You’ll probably want a pretty stiff boot though like the Seba SX. I’ve seen people skate them on the K2 Unnatural and they seem to like them, but most aggressive boots probably aren’t stiff enough.

There’s always going to be the comparison to the Wizard frame. Unfortunately I haven’t skated the wizards enough to really have an option on them, but look forward to getting a pair for a future review.

Even with the length and big wheel feeling, I love skating these frames. There’s a floating feeling you get with 4 by 100 wheels that’s hard to describe. If you have a solid UFS boot, you might want to pick up a set.

Kizer Arrows UFS Frame Review

These are the Kizer Arrow frames. They’ll run you around $90 US. They’re UFS and fit up to an 80mm wheel. This means they’re perfect for aggressive skaters interested in trying big wheel blading.

They have an aluminum core with replaceable plastic sidewalls. This gives you a solid ride with protection for grinds. 

Over the next few weeks I skated them in my neighborhood. Eventually, I decided to take off the soul plate and mounted the frames directly on my boot.

The Kizer Arrow are an interesting frame. The frames are strong and responsive, and if you have a Seba boot, they feel amazing directly on the carbon shell.

If you were planning to take these frames to the skate park and doing some grinds, you’re going to be pretty limited. 80mm wheels are also pretty large for carving transitions, and I found the wheel base was a little too short for me to land comfortably.

If you’re interested in doing some big wheel blading on a UFS boot, these are probably a safe bet.

Disclaimer: I paid for these frames, wheels and bearings at retail, but I found a great coupon at InlineWarehouse for 20% off.

Ground Control TriSkate Frame on Razors Shift Inline Skate - Review

These are the Ground Control TriSkate frames. They're UFS and come complete with 110mm wheels and ABEC 9 bearings for $140 US. You can also get them with 125mm wheels, or with just the frames. They've been optimized to ride with the Razors Cosmo skate, or with the Cosmo soul plates on the Razors Shifts. 

Why would anyone want such huge wheels? The bigger the wheel, the more cruising speed you get and the smoother the ride. With three 110mm wheels, the length isn't much longer than 4 80mm wheels, so you don't have to adjust your skating. 

With the IFC system on the Razors Shift, these frames are ideal for skating around between grinding sessions. I wanted to see how they worked in real life, so I brought them to the skatepark. 

Changing the frames using the IFC system on my Razors Shifts was pretty effortless. It took only a few minutes to pop off my grinding frames and put on the Ground Control frames.

I skated to the next spot, stopping to play around at the city park.

Over the next few weeks I brought both frames with me, skating from spot to spot, swapping out my frames whenever I found something fun. It was really great having the big wheels to travel longer distances and to smooth out the rough concrete.

Would I recommend everyone gets them? Probably not.

Being UFS is great, but the wheels extend a bit above the frame to the inside of the soul plate recess. This is no problem if you have IFC boots with the Cosmo soul plates, but any other UFS boot will need to be modified to fit them. The Kizer Trimax frames are also 110mm UFS and will fit any UFS boot. (Try them on SL3)

The Razors Shift boot flexes a lot, which is great for topside tricks, but makes riding really tall frames a challenge. I'd bet this is less of a problem with a 45 degree buckle like on the Cosmo boot, but it makes me less stable.

If you're planning to skate long distances without a need for grinding, you might be better off getting a dedicated TriSkate. For $50 more, you can get yourself something like the Powerslide Imperial Supercruisers. They're much lighter, fit better and are designed for big wheel skating.

The Ground Control TriSkate frames are a welcome addition to the Razors IFC lineup of skates. I love the feeling of big wheels and being able to get from spot to spot easier. But if you don't have the IFC, or need to switch between grinding and long distances, you might want to skip them.

Oysi Inline Skate Frames - Review

I haven't been this excited about a new skate product in years. The Oysi (aka Oysius) frames feature a wide split, built in rocker and a groove to prevent wheel bite. They're a dream come true, or are they? I tried them out in the neighborhood then took them to the Durham skate park to see how they hold up.

Go Project Crown Inline Skate Bearings - Review

These are the Go Project Crown Bearings. They'll run you around $80 for a set of 16. These bearings are, different. Instead of the normal one piece design you're used these bearings have this little copper crown that slides in the middle.
