Groupset: Shimano Tiagra 4500 groupset (sora brakes) - change to 105 5700
Cockpit: Giant Connect bar/stem - not sure what to do, would like to keep it under $100 here
Saddle: Selle Italia Gel Flow - happy with it, don't want to change
Tyres: Michelin Lithion 2 - don't match my new bike

Tubes: Vittoria Ultralights - don't want to change if it means more punctures
Wheelset: X-Keymet XR300 (1550g according to my kitchen scales) - I feel these are fine for now
QR: titanium - came with my wheels, 46g on my kitchen scales, don't think I can do much better
Bar Tape: stock Giant stuff, no idea how much weight I can save, and if its worth saving
So basically I want to know if I can get a better bar/stem combo than the Giant Connect for under $100. I think I am pretty limited in terms of groupset choices as I think I need shimano BB71, will be happy to hear more info concerning this
