105 build weight
I just finished installing all the components on a new build on a carbon frame using up various spare stuff and purchasing cheapo where i didn't already have spare components.
drive train and brakes - shimano 105
wheels and pedals - low end shimano non series
bars, stem, seat post - aluminium
saddle - reasonably light 225g claimed
fork - carbon with carbon steerer (Real Design)
I was surprised how heavy the whole thing came to. The frame is 2.8lbs and the complete bike came to 19.2 lbs (no bottle cages). Is this the sort of weight other bikes with 105 group, cheap wheels and non carbon components come to? How much lighter would an ultegra build be?
When I eventually replace parts I might do the upgrade if it makes a noteable difference in weight but I wouldn't change anything right now since the purpose was to use up spare parts. Just curious and surprised by the weight.
p.s no picture for the moment as I haven't put on the new tyres and bar tape. That'll be next weekend's task.

I'm too lazy to look up the link right now, but when 10 speed 105 came out there was a review comparing it with Dura-Ace.
The ENTIRE 105 group was almost 1 lb heavier than the ENTIRE Dura-Ace group. That's one expensive pound.
On your build, low end wheels are costing you some on weight, and depending on what they are...I've seen seatposts and stems that are boat anchors.

It sounds like the 19.2lbs is about right for a 105 equiped bike. I was just curious how much a typical 105 level carbon bike would weigh if bought as a complete bike compared with the components I used. The bars stem post are Deda (piega, logo, metal stick).

Yeah, 19.2 lbs is light enough to race and win. Work on the engine.

Sounds about right. With low end wheels, you could save a full pound off those easily. But as mentioned above, you can race and win on what you have.

1) I was expecting a bigger difference from my early 90's steel bike of 22lbs. I keep reading people claiming 16 lbs and 19 is a long way off.
2) You mean I should have weighed each of my spare components, added up what the total would be before I built it, considered alternative permutations and aimed at a target total weight? I was using whatever I had already. And weighing components;that's obesessive!
You sir are a weight weenie and you shall be cast into the lake of fire on judgement day along with the rest of your road nazi minions and your cervelos!

Did the early 90's bike have downtube shifters and 7 speeds on the back but 2 on front? Brifters weigh a bit and add length to the shifter cables, then you have 3 more cogs as well.

actually you described the steel perfectly in it's original state. But the 22lbs was after i upgraded to 10 speed 105 last year. I intend to put the steel back to it's original state (or turn to fixie) now I have a new frame to hang the 10 speed stuff on.

I'm guessing you meant the opposite. Or were referring to yourself. Otherwise your writing is coming along nicely. Good luck on Alpe D'Huez!

FWIW My aluminum (scandium) build came to 17.5 lb with mid weight (1750g) wheels and Ultegra 10s (8s brakes).

the drive train was swapped over. brakes and bar/stem/post were new and clearly was not light. i think i might get some nicer wheels next but not until I've re-tuned the engine.

Good point.
I'm spending time on an 09 CAAD9 5 with CF tubulars, and a Thompson post, and stem. Fully built the bike come in at around 16.7. Not bad for a sub 2K bike.

The Giant TCR-C came in at 16.7lbs and the Boreas Ignis (Ally Frame C.F. Forks) came in at 15.5 lbs.
Those wheels and tyres can add a lot- and Ally components can be a lot heavier than you think.
Mind you- these are small frames so take that into account aswell.
