Are you looking to buy the fastest and best roller skate bearing on the market? You have found them. We built this bearing from scratch with JESA of Switzerland. Not only did we use aerospace-grade steel for the outer race, but we also double-polished the outer and inner race to provide the least amount of friction possible. The balls go through a number of stages of polishing, far more than any standard ABEC 5, 7, or 9 bearing to make sure that they are as round as possible. To help reduce drag, Jesa increased the radial clearance providing slightly fewer total contact ball patches. Additionally, the lightweight plastic cages allow for lower rolling resistance. Finally, we use a special lightweight racing oil from Germany called Kluber oil to top the bearing off. The result is the fastest steel skate bearing on the market. 

  • Bearing type: 608 8mm 
  • Dimension: 8mm core, 22 outer diameter, 7mm width
  • Protection: 1-Z shield
  • Cage: TN9-plastic cage
  • Ball complement: 7 pieces
  • Ball material: High-grade steel

Pack of 16 pieces.

Spaces not included.

To ensure all of this hard work in creating the bearing actually works in practice, our professional inline skating team which includes a number of world champions tests the bearings in real work conditions to confirm that these are the best roller skate bearings. We complete back to back lap time comparisons as well as roll tests. Our roller derby team tests the strength of the bearings in bouts. Our testing confirms that there is no faster steel bearing than the Bont 608 steel roller skate bearing.

Upsize
Color: Pink, Size: XX-Large
Knowing to upsize before I bought the shirt was a good thing to know. Otherwise, it is a very nice shirt

No flaws, not high end
Color: Pink, Size: Medium
I nabbed this for my in shape 14 year old son who had an upcoming wrestling banquet. It fit very true to size for him however as a low-mid grade dress shirt it had little flex or mobility across the chest and that’s ok, this is an entry level dress shirt and perfect for this and similar events. The color was vibrant and well saturated, and the fabric itself was thin enough for some transparency but thick enough to be considered medium weight. It would not be a cooling dress shirt. It did not have a soft hand, rather a sturdy rougher feel akin to a dress shirt a restaurant server would wear and laundry frequently which is also ok because it is exactly what a polo in this range should be. If you are looking for a flexible chest and soft touch you will need a better fabric blend and you pay a lot more for that. The buttons were nice and collar looked good. I would recommend this for any average event or occasion or even for work. If you are looking to impress on an interview or a date or during high heat you might need to look elsewhere. For what it is it’s perfect. Buyer and shirt need to remember this and keep it in its shirt lane.

Good shirt, not great, but it was never trying to be
Color: Navy Blue, Size: Medium
Let’s start with the fabric. The 50/50 cotton-polyester blend sounds like a compromise, and I suppose it is — but it’s a good one. You get enough cotton to feel like an actual shirt and enough polyester to keep things from turning into a sweat tent in the heat. It holds its shape after washing. No complaints. The collar is a genuine highlight. The pin tips keep the points flat and symmetrical, which is a small thing until you’ve owned a shirt where the collar curls after two washes. You’ll notice it. There’s also a hidden plaid print under the collar — a subtle detail that’s only visible when unbuttoned. Unnecessary, but charming. Fit is true to size. Order what you normally order. It’s versatile enough to tuck in for the office or wear loose on the weekend. Not going to replace your best Oxford. But at this price, it was never trying to.

No bleed through of t-shirt color beneath. Very hard to achieve, but Alimens does it.
Size: X-Large, Color: All White
At the price point of this shirt, i'm super impressed with the overall quality, fit and appearance. I have had short sleeve white from others in the past and what sets this apart from them is this ... this needs no t-shirt underneath. if you did choose to add a t-shirt, the t-shirt color will not bleed through the white optics. I am daily shirt and tie guy, who loves button downs. I own many VH brand shirts and this Oxford is sized exactly as a VH. Will be ordering more!!
