Imagine how things could be ... then work to make it a reality

I've been on Spark for a while now ... however, in the past 1 - 1/2 years I have been gone. A back injury basically kept me from doing any real exercise ... but time to change that. I gained back about 10 of the 17 pounds I lost. Not to worry though, I just need to get back on track ... here we go woo woo.

Now that I got the touchy-feely stuffs out of the way....I'm Greg.

I live in that other place. "Other" place??? Well...I mean near Portland. Not Portland, Maine...that other Portland, near Oregon. Actually, I reside in Washington. Uhhh...not D.C....the other Washington...the state I mean. And while we're at it....let's toss in Vancouver. No, no...not Vancouver BC...the other Vancouver! Seeee...that "other" place.

I REALLY appreciate your very helpful comments on my music blog... between Tom Jones and a "mish-mash of crap" I'm sure I'll be grooving in no time!!!

I remember that from my March visit - raining most of the time I was there! It was fine, though, because it was intermittent and not so humid. Like it rained enough that there wasn't any humidity in the air. It was lovely.

I'm still in the intro of the chi running book. So far it seems to be about finding a way to run without getting injured. I'm all for that so I'll see where this goes.

Hi Greg,

Oh boy! Did you ever open the floodgates!

By far the majority of aluminum bike frames are made of two alloys.

Alloy #1: 6061-T6

Most aluminum bikes are made from 6061-T6, which is primary composed of aluminum, magnesium and chromium. The "T6" designation refers to heat treating process that "evens-out" constituent alloys within the structural matrix.

There is also an "artificial aging" process where the alloy is subjected to 250 to 400 degrees F for 5 to 48 hours. This "artificial aging" process stabilizes the material's properties that may take years at room temperature.

Note: that 6061 is not pre-heat treated. A bike frame made of 6061 has to be heat treated after the frame is welded together. This means that all 6061 frames stress relieved after the construction .


Alloy #2: 7005-T6

Higher-end bikes are made from 7005-T6, which is primarily composed of aluminum, zinc, magnesium, manganese and chromium. 7005-T6 requires stricter controls on contaminants such as iron, copper and silicon than 6061-T6. 7005-T6 comes pre-heat treated and only requires artificial aging after welding.

7005-T6 is harder than 6061-T6, less flexible and has a higher yield strength of 52,000 psi, which allows frames made of 7005-T6 to have less cross-sectional area and thereby lighter. However, the stiffness of 7075 over 6061 may mean a harsher ride. For me, lighter and stiffer is better since the bike is both faster and more responsive.

This is where the confusion over frame quality enters the picture. Artificial aging is not the same as stress relieving. A 7005 frame will be okay without stress relieving. However, post construction heat treating relieves construction induced stress and makes the 7005 frame bullet-proof.

However, a high-quality 7005 frame is about $300 more expensive than a comparable 6061 frame.

A triple-butted frame has three different tube thickness along the length. 6061 frames tend to be double-butted due to a lower yield strength. True triple-butted frames, such as the 9:Zero:7, take advantage of the higher strength of the 7005 alloy to make the mid-section of the tube thinner than would be possible with 6061 and yet maintain high strength.

Although it does not seem worth the extra expense, the 9:Zero:7 frame is 6 pounds lighter than the Salsa Mukluk frame which is made from 6061-T6.

I demoed all the top fatbikes available at the time, including those from Salsa and Surly. I was pretty much convinced I was going to buy the Mukluk. Then I demoed the 9:Zero:7. There was no comparison. The 9:Zero:7 ruled!

Any questions?

Bruce

Hey, Greg, thank you so much for watching and commenting on my video blog! I'm gonna write you more tomorrow because I have some questions, but for today I'll just say thank you and wish I weren't too tired to think of some witty response to your--I'm not kidding--UNFLAGGING WITTINESS. I LOVE reading your stuff!
