Complete group weights from lightest to heaviest:
8. Sram Force, 2435.60 grams
Now being that this is WW most of the variables will be replaced with others, so lets look at just the key pieces. (removing cranks, bb, chain, brakes and cassette.) Replacing cables with an averaged light setup such as Alligator. (100 grams for brake and 60 grams for shift.)
6. Sram Force, 771.5 grams
Just adding up components from SRAM's site shows the complete force group at 1968g (albeit, without cables/housing/etc). That's not even close!? Did I miss something here or did they really overshoot their weight by over 200g?
For the core only it's 729 after adding 160g for cables but that's still 40g off.
Maybe it's just a surprise to me because I'm new to counting grams but that seems more inaccurate than I was expecting. I also used the Force example because that's what I'm building up my new bike with.
I think that the weights listed for SRAM Force on this thread are a bit off as well, for the shifters at least. I Just installed 2012 Force on my bike, and weighed the parts:
- Shifters 351g with shifter cables, I suppose set of uncut shifter cables are at least around 30g, so the shifters without cables should be around 320g or less?
- Brakes 288g
- GXP compact crankset 175mm 676g (I suppose the standard is 30g heavier?)
- GXP BB 109g
- RD 173g
The FD was Sram Red 2012 (85g with chain catcher) and with Ultegra cassette (11-23 207g) and DA chain (114 links 262g) the groupset was around 2100g without cables with the chain cut to correct lenght. But still, I don't see how you can get the GXP groupset under 2100g with SRAM cassette and chain as claimed.
