I have a question im planing to buy a Caad 10 but after reading alot of people having issues with the bb30 bracket i mean changing them very often the bearings i kind of turned off by it .

And i did some research and find out that the shimano hollowtech II is a much better design and last longer than the bb30 i know there is a long debate on this i red it already but anyhow seems like the shimano need less maintenance and i saw a conversion kit online to convert to it ofcoure i would need to buy a shimano crankset because of the size the fsa is too big, anybody has done this or what is your honest experience im a very handy guy but i don't want to replace bearings after i got caught in a rain or very often if i can avoid it
some people says after 100 miles they needed to take the bike to the shop.

Appreciate your opinion.
