A bottom bracket built to outlast your frame - BB ALPHA features hardened stainless-steel races hand-built with grade-3 Silicon Nitride ceramic balls, custom-engineered seals and precision dust covers, delivering up to 500% better moisture protection, while still providing ultra-low friction performance. The simplified spacer tube design and lighter 7075 aluminum cups ensure quick installation and a 10% weight reduction over previous generations. All CeramicSpeed BB ALPHA models are handbuilt in Denmark and backed by a lifetime warranty.- Hardened Stainless Steel races offer exceptional corrosion protection and provide an optimal surface for the hand-built grade-3 Silicon Nitride ceramic balls
- Internal ball bearing race has been redesigned to provide additional support, allowing the bearing to better handle pre-load
- Custom-made light contact seals with stainless steel covering the backside strike the perfect balance between efficiency and protection, while offering the trademark low-friction CeramicSpeed performance
- Inside the BB ALPHA, the bearings have been moved further out in the cup, allowing the incredibly stiff POM plastic dust covers to now sit flush with the outer edge of the cup, making it increasingly difficult for debris to penetrate the dust cover and contaminate the bearing
- Simplified spacer tube design and lighter 7075 aluminum cups ensure quick installation and a 10% weight reduction over previous generations

Very Impressive Quality
Color: Bubble Dark Yellow, Size: Throw
I don't normally write reviews but my search for a low-cost quality throw for my sofa is finally over, right down to the "dark yellow" color. The quality of this throw is amazing for the price, it's just thick enough and very luxurious looking and feeling. I washed it straight out of the box upon delivery fully expecting an issue so I could return it asap. I used the delicate cycle in cold water, low heat in the drawer and it looks better than when it arrived. I ordered several other throws for $20 or less on Amazon that were too thin or the color was dreadful, but this item was perfect in every way. No shedding so far.

I LOVE THIS BLANKET!!
Color: Pink, Size: Throw
Just buy it right now because it’s very affordable, high quality, and soooooooo silky soft. Feels similar to a Minky couture blanket, only with longer fuzzies. I got the one sided raspberry pink looking colored throw size and I love it. No regrets, easy to wash, and doesn’t fall apart in washer. I love it and will buy more in the future, highly recommend🩷🩷🩷

Great product!
Color: Double Sided Tie-dye Pink, Size: Throw
We ordered the pink tie-dye colors which is gorgeous so we ordered 2 more in different colors. They are soft and the weight is perfect. A great blanket for bed or snuggling on the couch.
