hi y'all. i have a 2007 masi speciale fixed, and i want to upgrade the crankset. it comes with stock truVative touro 1.1, 48T chainring. which i think is pretty ****e. want to replace with sugino messenger rd, 165mm 48T chainring. don't want to spend a ton, so do you think this is a good move? would have to replace a BB as well, correct? how do i order the correct/proper crankset and BB, so that i can take it to my LBS to replace? any help/advice for a novice would be greatly appreciated. happy holidays!
