Hey guys i just bought my first road bike a new Giant OCR 3 and i'm wondering if i want to eventually upgrade parts of it where i am going to get the best value for money as far as performance is concerned.<br /><br />At the moment its stock apart from clipless pedals and computer and i was looking at whether or not to go to narrower tires for lower rolling resistance, new wheels, lighter fork etc. <br /><br />So far i have found the Sora groupset to be pretty good and i'm planning on running that till it breaks/wears out and then upgrading to 105.<br /><br />As far as what i plan to do with my bike, I'm going to be riding 5 or 6 days a week and plan to train seriously for some long distance rides/races. Even though i know its probably counter productive for becoming a good long distance rider i do a fair bit of heavy weight training as well so i'm about 92kg at 179cm<br /><br />Thanks in advance
