Hey all. I'm pretty new to cycling and have a few questions as i'm still a noob about the mechanics of the bike. I just purchased my 2nd road bike, a Trek Madone 2.1 with SRAM apex groupset with a compact crank and 11-32 cassette. I plan to race on this bike, so I want to upgrade to a standard SRAM FORCE BB30 2.2 Crankset and the pg-1070 cassette (12-27). Will i also need to purchase an upgraded bottom bracket for the crankset to work with this bike? Also, i think i will need to upgrade the chain but someone correct me if i am wrong.

thanks for the help
