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

Good option for people that carry a lot with them
Color: Silver
Very pretty purse for a dressy occasion. I always carry a lot of stuff with me and this actually can fit it. The option to be able to unfold the top to give it more room to put stuff in is fantastic! I love the 2 different strap options as well. It comes in a nice drawstring bag for storage. Very happy with this purchase.

Great for everyday or special occasions
Color: Wine Woven Suede
Mine is brown and I use it daily. Dresses up a sweat set, works as a real clutch for dinners. I'll definitely buy another color.

Cute Look, Mid-Shelf Build
Color: Black Woven Suede, Color: Black Woven Suede
This purse looks like it’s going to impress — that woven pattern gives off designer energy without the designer price. In reality, it’s more of a lightweight, occasional-use accessory than a daily driver. The suede-style material is soft and easy on the eyes, but it isn’t exactly robust. The structure feels thin, and the bag doesn’t have much internal organization. Think “carry the essentials to dinner,” not “load this up and hit a full day at the office.” The gold accent is cute, but again, decorative more than durable. For the price, it’s fine for a night out, a holiday party, or when you want something small and polished. But if you’re looking for longevity or any kind of everyday functionality, this stays firmly in the fashion-over-function category.
