Après 2 mois d'utilisation, tout rouillé!! Beaucoup de bruit une fois graissé... ne perdez pas de temps à économiser ici.

Ok, sure, they appear elegant ootb. However, once I handled them, it was clear they were of low quality and I'm pretty sure the bearings (not sure if steel or ceramic) were never greased, and there was significant play and both audible and physical clicking. These issues were amplified tenfold when pedaling, but I was in a bind and needed this part to at least function to get to work (I commute primarily and solely by bicycle). This all began straight from delivery last May. It's now February 2024, and they need to be replaced ASAP. One wants to disassemble any chance it gets, and the pedaling has become much more rough and it's actually affecting my performance and my speed and it's gotten to the point where I don't really feel too safe riding because I'm afraid it's just going to fall apart from inside my frame. I don't know about you all but I'm sick and tired of these subpar manufacturers just half a**ing they're products just for profits while we the consumer are left with nothing of quality and durability in today's world . Also, if you notice in the picture if you leave these colored parts out in the sun for not even a full day they begin to fade fast so my advice is to keep it inside or keep it covered. I've gotten screws, bolts, all kinds of hardware, parts, components, brakes, you name it with red accents... all pink now

Not a bad bb if you replace and grease the bearings assuming the race is milled right. I returned mine as I expect them to at most require greasing, kinda silly to ship these defective ootb.

I bought one of these because I needed one quickly. The colors is good and installation is pretty easy with the right tools. I did have an issue with on of the dust covers. My crank spindle was very tight fitting and in the middle of installation it cracked. I reached out to the seller to see if I could get a replacement part. They responded very quickly and took care of my issue fast courteously. We will what the longevity will be, but the seller is top notch in service.
