I know this has probably been done to death... Clicky bbright bottom bracket on a Cervelo R3.
The first one that came with the bike (SRAM?) lasted a couple of weeks.
The second one (Wheels Manufacturing as per below) lasted about a year, I replaced the bearings and it lasted for another year.

After that I tried the new style screw together wheels manufacturing one, which lasted less than 6 months. Changed the bearings and the click is still there!!!

I did think about putting new bearings into the first wheels manufacturing one, but worried I'm throwing good money after bad. Instead I'm going to defcon 1. Changing to a Shimano Ultegra 24mm crank and putting in outboard bearings with a Rotor 4624 bottom bracket.
Am I wasting my money?
