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
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
