Im 21 years old and working up the USAC racing categories, losing body weight is not an option (60kg @5’9) Im currently on the market for a new race bike. I’ve decided to go with the Giant TCR (carbon wheelset, dual sided power *on both models discussed here) I simply cannot pass up the value for money and Giant will replace frames for free if damaged while racing (pretty sweet deal!) The Rim variant is 15.5lbs and the disc is 16.7 lbs! As someone who lives in the mountains i’m very confident with rim brakes but the sound of great braking in the wet sound very nice considering it rains here 30% of the time. I plan on doing crits where weight doesn’t matter as much, however I plan on doing several climbing road races and uphill time trail series. My goal is solely on racing and being fast will the 1.2lbs of extra weight on the bike REALLY be that detrimental and or is it worth it? This is a VERY big decision and one that will last me for the foreseeable future, so making the right choice is paramount. Any help is greatly appreciated.
TCR Advanced Pro 0 Disc (16.7lbs)
TCR Advanced Pro 1 (15.5lbs) - would upgrade this to Di2
