If you haven't found the weight for a component in our database,
we'd recommend you to post a request in our forum.
There's a good chance that someone out there knows what you're looking for.
Please do not contact us to ask how much x component weighs -
if it's not in our database we don't know it either.
I've submitted a weight, why hasn't it appeared yet?
Every submission is thoroughly verified for plausibility, correctness and so on.
We get vast amounts of submissions every day, that's why releasing might take some time.
→ How do you verify submitted weights?
By supplying all necessary details you can make sure that your submission is being released as fast as possible.
If your submission hasn't appeared after a period of 14 days, it was most likely dropped.
→ Why was my submission dropped?
necessary details are missing:
Example: a frame weight is useless without the size.
Always supply as much details as possible by following the instructions aligned
right to the comment field on the submit page.
Visit the website of the manufacturer (URL's can be found in our manufacturer link collection).
If you're looking for the claimed weight of a past model the Internet Archive Wayback Machine
is often the solution. It has archived the content of many websites back until 1996.
We provide direct search links to it for each manufacturer website in our manufacturer link database.
Another good source are printed manufacturer catalogues. Note: weights listed in shops are not necessarily the official claimed weight by the manufacturer.
How can I determine the model year of my component?
Unfortunately only a few items have stamps showing the exact production date.
If you couldn't find such an item on the part or it's packaging it's important to know
when you bought the component.
We highly recommend to add this information to the comment field between September and February
(where the majority of model changes takes place) or when you're unsure in general.
As a rule of thumb you can say that items bought before the annual Eurobike/Interbike
are from the last season while items bought afterwards tend to be from the upcoming season
the more time has gone since these exhibitions.
Preliminary note: We already have many bikes yet to add, so don't
be surprised if it takes some time to publish your bike.
If your bike is below the max. weight stated in the corresponding categories in
our articles section,
email us with a detailed list of all components your bike consists of and
a picture (or more if you like) in good quality.
Accurate scales are important for reliable weights.
You don't need to have a calibrated 0.001 g laboratary scale in order to weigh parts,
but it wouldn't bother us. ;)
Our recommendations are as follows:
Always weigh in grams:
converting from lbs to g gives inaccurate results.
Use scales with a matching resolution:
→ 0.1 g resolution
→ 0.5 g resolution
→ 1 g accuracy
→ 2 g accuracy
→ 5 g accuracy
→ 10 g accuracy
→ 20 g accuracy
Weighing a frame with a ± 50 g resolution (+ possible inaccuracy) doesn't make much sense.
Especially smaller parts (like headset spacers) should be weighed with a very accurate scale.
(this is where the lab scale comes in)
Weighing your bike
It's highly recommended that you verify the complete bike on an accurate hanging scale.
Don't just add up all the components you've weighed on your regular scale!
Why don't you have a category for complete bike weights?
The reason is that it's almost impossible to get comparable weights for the same bike.
Let's do an overview about the possible variance in component weights:
Tyres: ± 50 g variance per tyre for the same model are not uncommon - makes ± 100 g
Tubes: same here - ± 25 g for a pair of OEM tubes are normal
Fork: ± 50 g due to different oil levels
Rims: ± 20 g
Saddle: ± 30 g
and so on...
300 g difference between complete bikes of the same model year and size
are easily possible - if the manufacturer didn't change the specs of the weight:
then you can additionally add the difference for a slightly reinforced frame or for changed specifications
because the manufacturer ran out of stock on certain parts during the production.
Then you can end up at ±500 g or even more.
Not to mention that some bikes aren't anymore in their stock condition:
parts were added or exchanged, the tyres are already worn out, ...
That's why we haven't added such a category and most likely never will.
