So I just built up my new s-works sl2.
Looking at published weights of components, frame and a very lenient 1800g wheelset, in total it still registers at 6586g ~ 14.5lbs.

This is what I'm looking at:
1100g 54cm SL2 Frame
2253g SRAM Rival Grouppo
350g SL2 Fork
220g S-Works Seat Post
175g Fizik Antares Saddle
220g 3T Pro Handlebar
150g Ritchey Pro Stem
1800g Just a forgiving number (my Jet 60s Weight in at 1720g)

Total 6586g ~ 14.5 lbs.

MY BIKE does not feel like 14.5 lbs, or even 15.5 lbs, FEELS more like 17 lbs.

How is this possible?

Cables, housing, bar tape, rim tape, tubes, ferrules, cable ends, pedals, headset, etc, etc.....

VA_Esquire

You could always scale your bike. Then you would have an exact number.

There is a lot that goes into a bike that you didn't include on your list. My SL2 weighed about 14 with 1200g tubular wheels, sram red, s-works crank, and zero gravity brakes, and lighter components all around. There is no way your bike would weigh 14.5 with heavier wheels, rival, etc.

Pedals are included @ 317g ultegra pedals, I did forget to list them though, and the bike is sans tape right now

I did omit rim tape, tubes, and tires.

Arn't cables and housing included in a grouppo total weight?

bigskyTi

Like the others have stated, you only accounted for a few things. Plus I'm not sure that the weight of the SRAM group includes things like cables, housings, chain. Then add headset, spacers, tubes, tires, bar tape (suprisingly heavy).

I've got a Litespeed Archon the in in the 14lb range and i've got lots of lighter bits than you do, my frame is about 1100g.

umd

tape, tubes, and tires can be almost 2 pounds... cables may or may not be included in the group weight, but probably not. Published weights are usually lower than actual weights anyway. Do you have the s-works cranks or rival cranks?

sigg.switz

That is a complete list....
Seat collar, hanger, headset bearings, were included on frame weight. I still feel like 1000+ grams for a few non-descript pieces is a lot to be un-accounted for.

sigg.switz

Rival cranks, my one beef with the rival grouppo - I'm not complaining, cheap as can be. I'll be replacing them soon. Thinking Easton EC90 or just a RED crank. Savings of ~100-150 g

umd

I completely stipped my frame and weighed all the parts separately but had about 1100g for the frame weight and about 370 for the uncut fork (about 330 cut agressively). If I add tires, tubes, cables, bar tape, and bottle cages to your list it becomes about 17 pounds. There is a lot of stuff that adds up that you are not accounting for. And even my list as detailed as it is (with actual weights), my bike when I weigh it whole still comes in about slightly heavier than it is on paper.

sigg.switz

If tubes and tires really add that much, then I suppose that is where my extra pudge is.
After I trim steerer tube and seat post, replace the Rival Crank that should take off a little flub - Hopefully to an acceptable level.

Anyone know of a cheap 1400g wheelset?

bigskyTi

Depends on what you call cheap. Teh best way to go would be a set of hand builts, but you could go with something like American classics, or Neuvation C50 tubulars.

umd

If I add up just the obvious differences between your build and mine:


-735g red/custom group
-70g 3T Doric Limited Carbon Seatpost 27.2x280
-21g Arione CX
-15g 3T Ergosum Team Carbon Handlebar 40mm
-31g 3T ARX Team 100mm 73d
-630g Reynolds + tubulars
-152g Speedplay Zero Ti

Total -1654g (-3.65lbs)

Convinced yet?

eric01

When you say "FEELS more like 17" are you weighing it on a scale or just guessing?

As several folks have already pointed out:
1) advertised weight rarely equals advertised weight
2) all of the extra bits (cables, housing, bar tape, bar plugs, even grease) are not 'free'. A lot of little things can add up


And my last point -- you can't be a weight weenie without a proper scale!

Flatballer

Don't forget skewers and spacers and all that fun stuff.

Plus, holding your bike in your hand isn't exactly scientific.

sigg.switz

I actually have a digital scale built into my shoulder. That being said it is 17 lbs from a bathroom scale. I don't care enough about the weight to get a scale, just wondering where the extra grams were coming from. Now I know, and knowing is half the battle. Don't do drugs.

urbanknight

Keep in mind the published weights are usually low, often by as much as 10%. Toss in the items you forgot to mention and I can see that easily. Tires and tubes make up a pound right there easily.

Cheap and light must mean you're ok with them falling apart on the second ride.

kudude

anyone have a weight on the williams 19s?

urbanknight

I believe they are sub 1500g.

leakysieve

Lets not forget that when you pump up the tires, you are compressing air into them and thus adding more weight.

urbanknight

Precisely why I never inflate my tires before a race.

trojanman

Do you drink water?
Does your bike have cages?

nycphotography

Tires ~400g (400 to 600g)
tubes ~150g (120 to 200g)
skewers ~100g (80 to 200g)
headset ??g
pedals ~300g (180 to 350g)
cables and housing ~250g (200 to 300g)

1200g = 2.64 lbs. that gets it close.

nycphotography

Aren't those supposed to be around 1050g? Your tires are 400g each?

Flatballer

The DV46T is 1315g in my spreadsheet. Add two tubular tires at 215 g each, plus glue and skewers (75 g if they're light) and you're up to 1800g.
