Which Groupset?

I'm running these at the moment on my supersix bb30 to a 6800 crank. No creaks at all. I've also used the FSA EE085 converters too (circa 80g, 40g heavier than wheelsmfg), no difference. The key thing here is to remember that if you ride in the wet, BB30 will likely creak (converters or not), all you have to do is take the crank off (shims pop off), gently lift the bearing seals up and regrease them, as well as give the lightest of coatings near the shell/bearing section just in case.

A lot of people attribute bb30 creaking to converters, when in fact they don't maintain the bearings properly, or install them incorrectly. No loctite needed for installation, just some marine grease, perhaps even doped up with tester approved MoS2.
