How much effort is made to try to estimate/engineer it first? Or even afterwards?

It's pretty much "let's try it and have someone put it through its paces," right?
It is and it isn't. Most people who build with steel usually use a variety of existing butted tubes for the main triangle and existing tapered, swaged and formed tubes for the back end. The options in wall thickness, diameter, length, butt profiles and alloys is staggering BUT not much has changed for many years so there's a decent record of what works and what doesn't in many circumstances.

Occasionally there's a game changing technological advancement (disc brakes, suspension and then 29ers with suspension) that makes everyone have to recalibrate tube diameters and wall thicknesses in certain applications but generally there's not much being done from an engineering standpoint in the small shops because they're really not building anything all that unique.

There's not really much failure analysis amongst small builders either, partly because we generally can't afford it, partly because it's usually obvious why a failure occurred by the mode of failure. In seven years of business, I've had two and was able to figure them both out within minutes. Had I not, I have a good friend and customer who designs parts for scanning electron microscopes and other similar equipment who has volunteered to do testing if I need it.

It's not quite the wild west out there.

All these awesome Ti frames and bars. Here's mine from my ride up to the dam this morning. A mass-produced LeMond, but then beggars can't afford to be choosers.

I don't really like the mate black anodizing, so I may painted in the near future.


Pretty aluminum bolts just for bling.

Oh yeah Enduro makes the wipers or you can still get the OEM and the inside orings and seals can be purchase from industrial suppyers or Ethan the guy that still tunes the Mavericks..

So far the 3 forks I have are trouble free, I really like the design and riding quality, specially from the dual triple crown like the one on the new bike..

hi Ricky!

i wasn't putting down Darios paint; i think it looks like he has a lot of fun with his paint, and i really like some of it.

what i didn't like was seeing how some of what looked like long-point lugs on a frame i was looking at were really just much more standard lugs with long lug tips added for purely cosmetic purposes; seemed like cheating to me.

i hope things are going well for you there; we miss you here!


cheers!

I would say it's close to the same vintage, too. Although I bet mine preceades it by a couple years. Ahead of it's time?
