Reddit mentions: The best inline skate replacement wheels

>As the title suggests. Picked up a pair of Macro blade 80 Rollerblade's with slow roll. I thought I was upgrading my Zetra blades but the Macro's seem so much slower( lots of work).

>Any suggestions on an Amazon upgrade wheel/bearing package for outdoor asphalt/concrete skate.

As far as free-spin of the wheels goes, the stock bearings for the Macroblades are a sealed bearing lubricated with a silicone-based grease. In general, grease-lubricated bearings do have a "run-in" period where they do not spin quite as freely as they will once they're run-in & warmed-up.

"Grease lubricated super-precision bearings initially run with a relatively high frictional moment. If they are run at high speeds without a running-in period, the temperature rise can be considerable. The high frictional moment is due to the churning of excess grease, which takes time to work its way out of the contact zone." (source)

Though, it should be noted that, in truth, oil-lubricated bearings also have a similar "run-in"/"break-in" requirement - see here.

As far as slower skating speed and requiring more work to get/keep going, the stock wheels for the Zetrablades and the Macroblades are of the same hardness: 82A. in general, a harder wheel rolls better, as a harder wheel deforms less under load, and loses less energy to hysteresis - "The primary cause of rolling resistance when a body (such as a ball, tire, or wheel) rolls on a surface is hysteresis. This is attributed to the viscoelastic characteristics of the material of the rolling body." If both skates were using the stock wheels (or identical replacements), both would experience the same energy losses, assuming all else is equal.

And, as you describe your Zetrablades as "well worn" & mention using a lithium grease to lubricate the bearings in those skates, I would presume that you are not using the original wheels or bearings in the Zetrablades?

With regard to potential upgrades, pretty much any serviceable bearing from a reputable company (examples: the ILQ series from TwinCam, or the Reds series from Bones) will do, and wheels for outdoor use should generally have a somewhat higher durometer than that of the stock Zetrablade/Macroblade wheels - something like these, these, or these (all 80mm/85A) would work well.

I have the 90mm hydrogen's on a set of baats frames and love them! Thuro has a sale on them and they are a great shop, run by skaters for skaters.

That said, I also have a set of these: https://www.amazon.com/KSS-Outdoor-Asphalt-Formula-Inline/dp/B01GOEJGOG/ref=mp_s_a_1_3?dchild=1&keywords=inline+skate+wheels+80mm&qid=1574295146&sprefix=inline+skate+whee&sr=8-3 on my k2 r80 frames, and they are a lot better then I expected them to be. For the price it's certainly a nice option to have.

I wish I'd taken a "Before" picture of my skates. They were filthy with dirt from lots of rolls over wet and muddy ground here in Philadelphia over the past few weeks. You can see how filthy (and worn down!) the old wheels were. I put about 575 miles on them.

I replaced the wheels with Hydrogen 80/85A wheels, the bearings with Rollerblade Twincam ILQ-9 Pro Bearings (though I got them from Inline Warehouse, not Amazon), and a new Rollerblade brand brake from Amazon. I also bought a Sonic Skate Tool, which really worked well!!! I got it from Inline Warehouse, too.

Took them out for their inaugural roll this morning, and although I couldn't skate at top speeds for long periods, due to wet, leafy patches, the spots where I could, they were AWESOME!

Like new skates again!

I bought these. Everyone loves that they light up. KSS 82A Skate Rollerblade Light Up LED Inline Wheels with ABEC 9 Bearings (4 Pack), 76mm, Black https://www.amazon.com/dp/B01GOEHXKA/ref=cm_sw_r_cp_api_4J9ZBb9Y8EVMP

These are not great wheels, in fact they are probably pretty crappy wheels. They are kinda hard for the size, have a weird profile, and tend to be kind of slippery on anything but rough surfaces.

But the cost to to miles skated ratio on these is off the charts, they are cheap and wear extremely well and come in several size and color combos: https://smile.amazon.com/KSS-Outdoor-Asphalt-Formula-Inline/dp/B01GOEJ5TW/ref=sr_1_fkmr1_1?s=sporting-goods&ie=UTF8&qid=1524265807&sr=1-1-fkmr1&keywords=kiss+outdoor+asphalt+formula

Had them on my skate around town skates for a few months, they are just unremarkable but dependable. They work fine and have not taken too much wear despite regular use.

I ended up going with Labeda Asphalt Gripper wheels. I got them on Amazon, search there. They're pricey, but I've been in them for a good bit now and, other than a rotation, can't seem to shred them. They're rated at something crazy, but still aren't too hard to use indoors.

If you want to shell out more, YouTube one of Bill Stoppard's videos. He has a video about a wheel that is unshreddable.

Edit: actually a bit cheaper than when i got them

And the video

Labeda Asphalt.

EDIT: Got these once and they were surprisingly decent.

If you're playing outdoors, you are going to go through a lot of sticks. By cheap ones.

You need some wheels made for asphault. These last forever; RINK RAT Wheels 72mm 84a PIVOT ASPHALT 4-Pack Black/Red Inline Outdoor Hockey https://www.amazon.com/dp/B00S72RSE4/ref=cm_sw_r_cp_apa_4dPQAb3EPM6H2
