AX-Lightness Europa
AX-Lightness Daedalus
New Ultimate

Bold Precision
Heylight HS II Superleicht
Alpha Q Pro Lite
Extralite The Post UL

Well good point but the syntace stem is 100grams (100mm) and realtively cheap. I didnt even factor in any AX-Lightness componets in here because no-one is rich enough to really afford that ****, but a AX-Lightness seatpost + saddle combo could probably drop 100 grams off the bike right there.
