Barbed Wire 8 Inline Skate Wheels 80mm 78a, Clear/Gray

Update August 3Wheels fell apart too quickly for the 6 or 7 times I used them. I've downgraded my review because they, like my other cheap wheels, are not durable. I would look for a harder wheel than the 78a durability.-----------------------------------------------------------------------------------------------------For the price, the wheels are fairly hard and very nice, especially for the price. Let me begin to make a short story long...I have been rollerblading most of my life. Recently, I decided to educate myself. I've always had standard rollerblades and nothing fancy. I took my rollerblades, $100 dollars, and slapped on some 100mm racing wheels with speed bearings that cost over $100 dollars by themselves. I then decided to take it a step further. I bought a pair or 110mm rollerblade speed skates that retail for around $400 dollars.At first I appreciated the 100mm wheels but here's what I learned. Whether or not you are a beginner or an expert, most likely smaller wheels are lighter and much easier and much more fun to use. I hated the 110mm speed skates and only used them once not because I'm not capable, but because I lost the simple freedom you get with smaller wheels and didn't even come close to noticing a satisfying difference in speed.In conclusion, my recommendation to anyone who may be wondering what's the best way to go, I'm not just accepting these wheels, I prefer them highly.Again, updates will come regarding their durability as I said because who knows if they'll fall apart quickly. I have another set of wheels I will try if these fail quicker than I'd like. Make sure you replace bearings that have been misused or overused or the wheels don't matter.As of now, 5 stars and perfect recommendation to anyone especially for the price. They are simple and useful without any further need for experimenting.

I got these to replace the wheels on two plasma cars as the original ones were just hard plastic and had no traction on our wood floor. They are a bit smaller diameter than the original wheels but work fine up front. At the rear they are a little too wide. I was able to get them in but to do it right the axial carriers need the inside portion that is closest to the wheel sanded down and a washer added to keep the wheel turning free. These wheels pick up sand and dirt from the floor but it wipes right off unlike the plastic wheels.

So far so good. Wheels appear to be well-made and have performed decently first couple of times out. Bought at the end of the season before the weather turned. So...I'll have to wait and see how they hold up from a durability standpoint. I expect that if they clock in at the 78a durometer, they will be soft enough to be comfortable, but hard enough to last for many-many miles. My last set of 78a's lasted more than 5 years on various surfaces including roadway asphault. bottom-line they seem to be a solid buy. 5-stars earned (so far).

As advertised. For the person who stated that he couldn't get the bearings off the old wheels which made this product useless; You cant knock off the whole bearings by trying to push the whole piece through the wheel. You need to get something that is a tad larger than the slot that goes through the wheel and push there. Try to imagine the bearings is shaped like a dumbbell; you need to push the handle through to take it apart and not the whole dumbbell.

I don't have much experience with blades, so I didn't realize these are just wheels without the bearings/spacers. You can take out the bearings/spacers from your old wheels and put them in here, but you might also just want to get wheels with everything together.

I don't know if the wheels not coming with the metal interiors is standard or what, but the wheels are useless to me as I can't remove the inserts from my old wheels.

I am very disappointed in these wheels. I have been rollerblading for 20 years and NEVER had a wheel disintegrate before. I used these wheels for about 20 hours, then rotated, per my K-2 instructions. After about 3 hours of use, both of my back wheels literally disintegrated while I was taking my dog for a run. There was nothing left of the wheels but the bearing, yet the other 6 wheels had minimal wear. Beware, as these wheels could put you in a dangerous situation.

Works as expected. I use them outdoors on concrete / asphalt surfaces and work well. nothing more to say than that.
