We’re working on estimating the total weight of the frame. We have a material spreadsheet we’ve developed over the past decade includes every bike material ever used along with all the relevant engineering data. With this spreadsheet we can get accurate within about 2% of the actual frame weight.
The reason there is any variation is because small variations in tubing add up to large variations in frame weight. We’ll post some examples later.
In the meantime, here’s a 25Seven post that might be interesting.
