I just purchased a FOCUS Izalco pro 2.0 from Wiggle and they installed the FSA mega exo BB30 adaptor w/ DA 7900 groupset Di2 and the BB is creaking on every stand-up pedal stroke. I have taken it to two local bike shops and all they do is pull the cranks and add more grease, re-press the bearings because they think they are not seated well, put it all back together, and I stand..."creak, creak, creak"! So I am left to swapping the FSA adapters to find another press fit BB30 solution for my FOCUS. I will say this, the ride is awesome and the bike is a monster on the road. I guess that is the one reason I have not thrown it over a bridge yet! HELP!!!! I keep reading about FSA BB30 needs 609 Loctite applied and all that, but that doesn't get translated well to the Japanese shops in my area. Does anybody know of a bulletproof solution to remedy the creaking noise. The bike is not even a month old, but I can't ride it because the creaking drives me crazy.
I'm getting a Specialized Tarmac SL4, and I plan to put a DA 7900 crank on it. The frameset ships with a Wheels Mfg adapter like this one:http://www.competitivecyclist.com/product-components/2011-Wheels-Mfg-BB30-Adapter-for-Shimano-7624.19.1.html
However, there is annother BB30 adapter available, which allows for standard BSA 68mm bottom bracket to bu used; it's from FSA:http://www.fullspeedahead.com/products/449/BB30-Threaded-Adapter-68mm
My question is, which adapter offers a more durable and less creeks-prone sollution? Accorning to a Shimano Youtube video, the BB30 standards is bad, since the bearings are positioned closer appart and thus offer less support to the crankset. From this point of view, the FSA adapter, together with standard DA BSA 68mm bottom bracket, is a supperior sollution. Plus I've also heard reports, that many BB30 users experience creaks in the BB area. What do you guys think?
