It begs the question why.

This may lead to a huge side debate, but for a lot of mechanics, the frame is actually the boring part of a bicycle build. Sure it's the centerpiece. Sure does it plane? But there's already a plethora of other issues one needs to address when assembling a bike that building your own frame seems like a misprioritisation of time for novices.

For example: will all the components of the drivetrain you pieced together actually shift well? Are the cranks going to clear the chainstays? Is the headset too tight? Do the brakes bite at the right moment when one pulls the lever? Why do the brakes squeal? Are the wheels properly tensioned and trued?

These details may not matter the first 30 minutes of riding a new bike. But 3 months from now, whether a bike has issues or not depends on attention to these details.

Most local bike co-ops have enough 80s Japanese frames that are still compatible with easily accessible parts that I don't see a strong proposition for building a bamboo frame other than a design gimmick. Steel frames are generally lighter, won't fail catastrophically, and are arguably more elegant.

But to answer your question, if you'd like to build a bicycle frame, I'd look into a class from any of the following:

UBI in Oregon - https://bikeschool.com/

Doug Fattic in Michigan (he has a three-week course) - http://www.classicrendezvous.com/USA/Fattic-Doug.htm

One of Doug's students has written a lengthy piece about his experience - https://medium.com/@ben.hudson/framebuilding-with-doug-fatti...

> Steel frames are generally lighter

I’d rather see numbers on that. My cheapo MTB is sure as hell not light. Depending on how much I have to pay for the materials, bamboo one might be lighter and provide higher quality of ride at the same price point (not counting work).

More expensive steel frames use butted tubes and higher grade steels.
If I need to pay $1000 for such a bike, I’d say it’s a very generous interpretation of “generally lighter”. As in, 90% of bicycles I encounter on the street on a given day are probably not that.
My apologies for taking your comment seriously.
Just realized where I remember you username from. You gave me a ton of food for thought in a bicycle maintenance thread not that long ago[0]. Thanks, being a newbie up until then I didn’t even know which terms to search for!

As I recall you were obnoxious in pretty much the same way then too.
