4130 Japanese Heat treated Cromoly, Ever heard of it? it's about 4 times as strong as aluminium but with near the same weight and no flex ,f*ck it's like you've never seen a good dirt jumper or a good BMX....

Each of these statements is confusing in one way or another.

Per equal volume/cross sectional area:

1.) Steel is stronger than aluminum. The ratio depends on what grade/alloy you are comparing.
2.) By definition of the Modulus of Elasticity: Steel is STIFFER than Aluminum. Again, it depends on which alloy you compare as to what that ratio is. This also makes steel harder to machine, and therefore more expensive to use. Al 6061 cuts like butter...(well, almost)
3.) Steel is heavier than aluminum.
4.) Aluminum is weaker in tension than compression has a much smaller fatigue life. Steel is equally good in compression and tension and has a much longer fatigue life.

So in the end, the engineers/designers weigh these factors and reach a compromise. IMO, steel is the winner, but then again I like custom made bikes and not cheap Taiwanese junk...

Am i the only one who thinks this bike is hideous? i mean all the other bikes that have been shown at interbike are all hydro formed, super high tech and awesome looking. then there is this thin tubed single pivot.

No, but you did say: "all the other bikes...are all hyro formed, super high tech and awesome looking."

Which implies that all you care about is how a bike looks...

flag odin333 (Oct 23, 2009 at 9:08)
no, notice HIGH TECH. i was comparing how all the new bikes are really nice looking, and this bike doesn't look like the greatest bike, and too be honest, most people who are experienced in metal fabrication would be able to make this bike with with basic tools.

flag audeo03 (Oct 23, 2009 at 9:21)
Yes, that is true. This bike is hand-made in Canada by bike enthusiasts using American made True Temper Super-Therm chromoly tubing. I'd rather have that than have some random Taiwanese guy/girl involved that cares nothing about the bikes using generic Taiwanese Aluminum.

I have to disagree a bit with the high-tech part though. Single-pivots work extremely well, especially for a DH bike. Brake induced forcings can be mitigated with a floating caliper. It's in the fork, shock, and brakes where I want to see the pinnacle of engineering design. Plus, look at Motorcycles. Single-pivots seem to work quite well for them...

One of Einstein's quotes is quite pertinent here: "Any fool can make something bigger and more complex. It takes a touch of genius and a lot of courage to go in the opposite direction."

flag odin333 (Oct 23, 2009 at 9:25)
yeah, but this is definitely not bringing anything new to the table. single pivots aren't the most advanced thing, but they aren't the best too pedal with. the design looks like something someone would draw in math class.

ok so basically: if you like it buy it (if you can), if you dont, shut up you're not forced to buy it or deal with it.

I would honestly think that stuff welded in Taiwan and China is probably of better quality and workmanship than stuff built in North America...any good welders here are scooped up and paid three times as much to work on pipelines and stuff. The people over in Asia are often welding bikes day in and day out from very young ages. I would probably trust overseas frames equally, if not more than hand-built in Canada.

flag Blindside127 (Oct 23, 2009 at 22:35)
Slopestyle123, If they made the same bike you ride out of aluminum, same dimensions and everything... you would be correct that Steel (Chromoly)would be stronger than an all aluminum frame. Depending on the grade of Chromoly it is about 4 times the strength of 6061-T6 aluminum per unit area. that being said there are a lot of factor that go into design. One for example is that aluminum becomes weaker around the welded areas unless you post process them, Where steel does not necessarily. Also as stated before steel has equal tension and compression strengths as a material... not necessarily true for the structural shape. Where aluminum has different values that depend on a whole range of factors that I'm not going to lay out. Simply put, it is absurd to say that one bike is stronger than another based solely on the material of the frame. Each one has to be engineered to meet the same demands, so they are equally as strong.

I have mixed feelings. Doberman knows what they are doing when they build with steel. Even though its supposed to be function over fashion, everyone will agree that when you plunk down your cold-earned cash that you want to be proud of how it looks. Nobody is going to pay 5 grank (per say) on a bike that looks dorky, even if it 'works'
