You know I am trying to save a bit of weight on my MXL.
I know...I know it is not a easy battle to win but I'm just cleaning up a bit.

So I see I can save 11+ oz by changing bar, stem, seat & post.
Ok so Im not into the minimalist 135 grams saddles but can live with Selle Italias TT which is advertised as 165grams.
Even reads 165grams on the suede cover.
It weighs 170 grams on a accurate postal scale.

Ok no problem close enough. Im trying to save weight but Im not a super weight weenie or I wouldnt be on a steel bike.

Next up the Alien Carbon post 270mm x 27.2 In their own literature they state 136 grams most internet sites read 130 grams.

Ok on the same scale they are 150 grams now 14 to 20 grams on something like this is getting up to or over 10% variance.

sigh.........

Ah well I hope the solida bar & stem are close to their *claimed* weights.

Advertised weights mean very little. Generally weights can vary + or - a certain percentage due to manufacturing processes. However many manufactures do not provide the mean wieght, but the "best case" scenario, and occassionally it's the best case - 10%.

There's very little truth in advertising when it comes to weight. I'm not sure how bad it is in road bikes, but for mountain bikes, it's amazing. Bontrager Valliant rims are advertised at 390g, and weigh in at 400-440g, Avid sold brakes advertised at 135g that weighed 175g. The list is long.

What the manufacturer says it weighs.
What the owner thinks it weighs.
And what my scale says it weighs. (ALWAYS higher)

A 20 lbs. bike needs a 15 lbs. lock
A 25 lbs. bike needs a 10 lbs. lock
A 35 lbs. bike doesn't need a lock.

I'm sure at some point they do actualy get these weights. You just don't know how they arrive at these weights. Is it before or after paint/finish is applied? What size is it? Do they include mounting hardware? The possibilities are endless. The problem is there is no consistent measurement standard.

You're weighing parts on a postal scale? Man, toss the scale and just ride.
Just bought a 110 SolidoNessism

Claimed weight, which is printed on the box, is listed as 130 grams for a 110 mm size.

Weight of stem without shim = 155 grams

Shim weight = 11 grams

Weight of stem without clamp bolts AND faceplate = 135 grams

Regarding the Solido in general, I really like it although it's not installed yet. Seems nice and sturdy - I'm actually happy it weighs more than the advertised weight.

Just think about all that nice steel - I'll bet it weights a whole lot more than adveritsed. Cheap too! You'd be so blissed out you couldn't ride.

You're not really happy or else you wouldn't have even sought out the weight info and bought it. You're just trying to put a good face on your disappointment.
I'd love to wack you with some galvi pipe ;-)Nessism

Of course, it would just bounce off your wooden head!

Honestly, I did know the stem would weigh more than 130 grams or I wouldn't have bought it. I'm not a fan of killer light parts although I don't mind paying a little extra for quality.

FYI, Excel Sports has some pretty good info regarding the actual weights of parts such as stems and bars. They list the weight of the Solido at 160 grams which sounded about right so I ordered one.

Yep, it's always a tradeoff and the marketing folks are just trying to make their stuff look good in a market full of the same. I'm just surprised that the obscenely heavy stuff still sells based purely on looks. Maybe this is an untapped market segment - really light stuff that only looks heavy, but is still strong! Why wouldn't just about everyone be happy with this?

There's also another website (independent) that lists lots of actual weights on things, but i don't have it handy.

Remember inexpensive, light and durable - pick any two.

I'm sending some quality stuff out to get galvinized!
