OK, so whats the best way to shave weight off your bike at lowest price. So ROI of weight for money spent. Stans NO-Tubes? How much do these save? Heres, an example of an I-beam saving... Kore Elite Carbon I Beam Seatpost 30.9 x 400 mm 185g $74.95 SDG I-Fly I-Beam saddle 145g $84 Total Weight=330g total cost=$159 my seat saddle combo was 750g =420g saving.. (nearly a full pound!) Anyone suggest other good value weight savers?
