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

Beautiful Purse but could be better
Color: Denim Blue
I ordered this bag without reading the reviews. I actually read them after I ordered it and it arrived today.
After receiving the product I do agree with some of the other reviews. I REALLY wanted to give this five stars but I didn't like that the purse was shipped in a sealed vacuum bag which flattened the purse and put it in a purse bag. I do love the leather, material, and style of the bag. I also love that it is a great size. I also think the price is a little expensive considering that the purse is out of form and placed in a plastic sealed bag. Because I've always wanted a denim hobo style type bag I decided to keep it and I ordered a purse insert which cost me another twenty plus dollars so that when I wear the purse it won't tip over when I sit it down.

BULKY & BUCKLING HANDLES
Color: Tan
The handles are bulky, and the leather buckles where you normally would hold it which is very uncomfortable. If you try to use the shoulder strap, the handles don't come off and get in the way when holding the purse against your side. Unfortunately, I first used it well past the eligible return date. I'm so disappointed. I would not recommend this product.
