Image result for sram groupset weights

I compiled a list of the weight  of the groupsets. I am repeating that if you want to a have light bike (a light bike translates into an efficient and sometimes fast bike)  If you must upgrade, its not only the looks or the brand but consider  the weight:(cost to weight ratio)

        1.    Frame sets

          Not all carbon frames are light review of a carbon frame circa 2011 showed a carbon built bike
          weighing 8kg +.  The Bianchi of some of RBP are said to be tipping the scales at 8.5 kg.  Some alum
          bikes by Cannondale, Giant Merida are light.

     2.  Wheelsets

         Typical wheelsets weigh over 2 kg.  Some more expensive branded weigh over 1.85 kg, those over
         P15,000 tip the scales at 1.7 kg.   Most carbon frames are 1.5 kg.   The branded ones are at 1.5kg.
         Am Cla came out with 1.4+ kg alum wheelsets.  The 350 and 420.   Light bikes.   Even Ursu, the
         Italian company have wheelsets weighing in at 1.6 kg.  But they have beautiful wheels   Aero wheelsets
         are expensive but their wind cheating features are what you pay for.  at 30+ kph, your ability to cut
         through the air is what counts, not the weight.

         Orig 450 carbon wheelset weighs 1,500 grams. SRP is at P30 k.

       Novatec Jetfly (which I bought) weighs 1,435 gtrams making my Freccia really sub 8 kg alum bike.

       Some Italian carbon fiber wheelsets weigh 1,300 grams and cost over P130K.

   3.  Group sets:    Component Weight Comparison from Total Cycling

        There are three major manufacturers:  Shimano, Campagnolo and SRAM. Their average weight is
        2 kg;   Shimano group sets are heavier, Campy is lighter than Shimano, and SRAM is the lightest.
        SRAM was the first with SRAM red 22 to be sub 2 kg.  (1.7kg)

        Weight comparison

        1. Shimano                                                                     PHL price

           105                               2.498 grams                         P18,000

           Ultegra 6800 8000        2,294 grams                           30,000

           Durace   9000               1,998 grams                           64,000




    2.  Campagnolo

          Chorus                        2,120 grams

          Record                       2,039 grams                           P80,000  resale unused

         Super Record              1,940 grams

   3.  SRAM

        Rival                           2,333 grams

        Force                          2,097 grams

        Red                            1,791 grams                       P130 k for e tap

      As you can see, SRAM red is the lightest of all. beating Durace by 207 and even Super Record  by 149.

     I got a SRAM red for the price of 105, and I will get soon a SRAM force shifter,FD and RD for the price of one 6800 shifter.  reducing the weight of my Ultegra 6600 which is 2,600 grams now by nearly 200 grams...

         Crank       FSA                              -  700 grams
         New Brakes (red)                              254                               vs     356                   (102)
         New Force Shifter                              307                              vs.    492 for 6600     (187)
         New FD                                              77                               vs     112                    (35)
         New RD                                           166                                vs     193                    (33)
         Chains                                               260
         BB                                                    400 grams

                          Total new weight           2,254

     It would save me 400 grams from my current Ultegra 6600. Wow that is a lot!.  You can feel that 400
     grams as you heave a bike....
