NO way that bike weighs much less then 13. Got any pics? Plus pedals are a vital part of the weight.

Your crank/BB is 150g heavier then mine, Brakes 150g heavier, post 80g heavier, Saddle 70g heavier, fork is at least 60g heavier if not 140g heavier as the CR1 forks are not the quoted 360g unless you have a 2005 model which isn't out yet so I'm counting on a 160g heavier fork. Only thing you seem to have lighter is the wheels, so -150g there.

Your bike is about 450g heavier then mine without pedals so there is no way your ride is 11.85lbs, more like 13lbs without pedals.

My scott will weigh about 12.6lbs with pedals( they only weigh 133g) and 12.3lbs without with a much lighter build. No way your bike ways 11.85lbs. :roll:

Chris first off :welcome: to the board.

Based on the limted list of parts you posted your Scott could not weigh what you state.

I must third, or fourth, that! All that Shimano stuff, nothing special except for those lightweight AC carbons and tires, there's something wrong with your math, or your scale. My 13.5lb TCR has nearly every component lighter or the same as yours, except for frame and bar/stem, and that's not 2lbs worth.
Sorry, but these weightweenies can weigh a bike from across the ocean, to within 100gms! This is *the* place for light bikes, and while yours is certainly worthy, it's no show stealer.

Happy gram hunting...

Also computer, in my opinion, and maybe an allowance for grease, etc.
Why do these paper builds never add up? Because they're paper.

Welcome, Chris, to WW world, where besides a password, one needs an Excel spreadsheet; photographed digital scale weights; preferably skill with a Dremel; lots o' cash or excellent-paying lawn-mowing work; and absolute evidence that you're not using a rebadged Simplon or a 2-tone DA crankset. Gandini's right: these guys smell kilos, grams and milligrams.

Careful: it's an interest that quickly turns into a fetish that becomes an obsession. :) So, on with the diet....

welcome on this board Chris,
as you can see you will be corrected "by each gram" as you are entering a dangerous area here!!!
the guys around here really know about everything so be careful when posting guessed weights...it's all pretty accurate here and we guys care for every gram. like explained above that can become an obsession but it's part of the fun and hobby we all share here.

so next time you do such an attempt give the full detailed specs. have a look at other spec sheets so you don't forget something. here's mine for example, although not with my lightest wheelset and not the most actual pic but anyway...:

While I am excited to post on the board and real excited about my Scott, I want to be correct in weight of the bike. SO I plan to get a better scale and try to prove myself worthy of WeightWeenies.

I lett you know my findings.

YES- completely!
my CR420 aren't great wheels. after just 90 km i had play in the rear hub. it was so much that it made a knacking sound. so i tried to adjust the play but there was no way to adjust it....when i finally disassembled the hub the rear bearings simply fell out of the hub! they didn't have a thight fit at all. so all i had to "glue" them back in with some special Loctite...not what you are looking for in a new wheelset. ok,ok - i got a free replacement rear hub within 1 week but i would have to re-lace the wheel to which i never did.

the wheels are ok for training. they are pretty light and look good. however my custom built CR350 with FRM SL hubs and 28/28 DT Revo are much stiffer. MUCH! and also 80g lighter (1292g vs. 1371g of the CR420 with Sapim CX-Rays).

my CR350 wheels feel even faster so aerodynamics of the CR420 also isn't too good in my point of view. nevertheless i used them as my everyday wheels. so after 1 year i decided to give them a overhaul at my wheelbuilder. he checked spoke tension but the re-thightened wheels don't feel any better either. the CR 350 of that same wheelbuilder are much stiffer. the rims are also pretty weak. my wheelbuilder said they wouldn't accept too high spoke tension because they start de-forming. sprinting and going down at speed is definitely wobblier than with the CR350 which really surprise me. they are even stiffer than some black Ksyrium SLs i used before.

This is quite strange... I have AC cr420 and I love them! I didn't have any problem with them, they feel fast and light. (well, I had Mavic Cosmos before...) Maybe it's because I weigh 120 pounds...
