If there is a valid functional reason for it, then it makes more sense.

you certainly have a way with words...

Its always a pleasure clicking onto this thread. Keep up the great work Tyler and looking forward to ordering a frame in the future.

I have to stop looking at Tyler's stuff.

I'll be broke forever!

@Tyler and others

I was wondering if there is no obvious gain in efficiency in production.

no treads means less stringent geometric tolerance and less operations at least for mass manufactured bikes.

[jerome]

What kind of tubing (double or triple butted, oversized) are Firely using and how much weigh a 29er frame with a PF BB30 and an integrated headset in size medium or 18"

best

Not totally sure what you mean here. If you mean "no threads" then I'll just assume that you are talking about the PF30 BB shell. Yes... there are no threads in the PF30 BB shell, but I would say that overall there are more steps and more labor involved in the use of PFBB's than threaded shells... from a [custom] manufacturing perspective. It might not seem so from an outside viewpoint, but there are a few extra steps and the shells themselves are machined from a much larger (and more expensive) piece of metal... also adding to cost.

Ti MTB tubing is either double butted or straight gauge (or a combination of both) 3Al/2.5Va, grade 9, CWSR. The tubing selection is primarily oversized, but always applicable to the end user's parameters.

Frame weights vary, even per "size", but I would guess a reasonable range (given no input info) would be 3-3.5lbs.

I really like that 29er with the non wishbone seat stays. What is the retail on a frame like that with a std bb and the 44 ht? Just in case, you can pm me -

If I had the monies, I would def get a FireFly, especially after seeing Ray's.
And that fendered one looks classy with the paint inside the fork.

Impressive work.

What a show!
I'm fascinated by the anodizing. Leni Fried has beeen doing it for a while now but I notice Seven will not warranty any frame that has been anodized. A quote from their site.

A small number of manufactures offer anodizing as a way of decorating the surface of titanium frames (or components). Basically, the process creates a dense, colorful film of titanium oxide, which adheres to the frame's surface. Ironically, this is the same type of oxidation that any skilled titanium welder will prevent at all costs, because it will cause the weld joint to become extremely brittle. (This is why Seven's expert welders bathe both the inside and outside of a titanium frame's weld joints in an inert gas, thereby protecting the molten metal from the high levels of nitrogen and oxygen that naturally occur in the environment.)

The titanium oxide film created by anodizing is, thus, extremely brittle, so the frame's surface cannot flex as it would during normal use. Cracks form through the anodized shell, which will eventually propagate into the tube wall, ultimately causing frame failure.

Seven strongly advises against anodizing titanium. Hence, we will void the lifetime warranty on any Seven frame that has been anodized.

Tyler, what are your thoughts on this?

Titanium fat chance mtb circa 1992-3? Still ridden today. Anodized.





I'll work on a real answer later... must build bikes now.
