Ever wondered why there is certain heaviness at the rear of your bike. It may be due to the GS:  the  crankset, the cogs, chain, the RD and the brakes.  Here is the  guide for  the GS weights:   you may spend more for the high end, but  saving weight makes for more  efficient pedalling, more watts for your forward motion, less tiring on your  part.

From Bikelane - Group set component weights.


Thus, Campy and SRA groupsets are generally across the board lighter than Shimano.  There is less weight variance among Campy GS,  big variance among SRAM GS and Shimano.

Thus for Shimano:    6800 is lighter  than 5800 by mere  91 grams;  Durace 9000 is lighter  than 6800 by whopping 409 grams!    Thus 5800 is  heavier than Durace by almost 1/2 kg!

For Campy:  Super Rekord is lighter  than Rekord by mere 99 grams,  Record  is lightervs Chorus by  only 81 grams

Across group set:  for the lightest:

          Durace                                 1,998 grams

         Super record                         1,940 grams (  58 grams)

         SRAM Red bb 30                1,741  grams  (257)   maselan for BB 30 frameset only

         SRAM GXP (standard)       1,845 grams   (153) grams

     

Weight comparison between Ultegra 6700 and 6800 mere 35 grams difference (lighter)

Weight comparison: Ultegra 6700 vs Ultegra 6800

	Ultegra 6700	Ultegra 6800
Chainset/BB	791g	765g (-26g)
STI Levers	447g	425g (-22g)
Rear Derailleur	189g	195g (+6g)
Front Derailleur	89g	89g
Brake Calipers	317g	335g (+18g)
Chain	267g	253g (-14g)
Cassette	209g	212g (+3g)
Total	2309g	2274g (-35g)

Comparison between RS 8000 and Ultegra 6800   -->   RS 8000 is actually heavier  (even vs Ultegra 6700)?

Weight comparison among 105, 6700 and  6800

Looking at buying a 2015 model Giant Defy Advanced, with either 105 5800 or Ultegra 6800 group-set. Did a bit of research on the group-set weights;

                      Ultegra 6700                Ultegra 6800                105 5800        Ultegra 8000
Chainset         791g                            765g                            736g                 674g
STI Levers      447g                            425g                            486g                438g
Rear Drlr         189g                           195g                             234g               200g  
Frnt Drlr            89g                             89g                               89g               106g
Brke Calipers   317g                           335g                            378g               360g
Chain               267g                           253g                            253g               253g
Cassette           209g                           212g                           269g               232g
Total                 2309g                         2274g                        2445g               2263

Ultegra 8000 is lighter vs  6800 by only 9 grams, and 6700 by  46 grams;   am I glad I got a 6700 for my Bianchi

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
