Hey what's the deal with the production frames, is there going to be any difference between the US-made frames and the Taiwan-made frames (other than the colours and where they're made)? Ie will the design be different or what?
Dave, I know this has been gone over before but I couldn't pick it up on the search function....the appearance of this bike on the UK forums has started people off saying it looks like the Edge bikes, I remember you responded to this before but cant find it to put them right!
Wasn't that a 2.7 Maxxis Minion you had on the rear of that bike? I thought I remember commenting on the size to Heikki when he was taking runs on it.dw said:
what is this I read earlier in this thread about a IH DW link Freeride frameset??? Inquiring minds want to know. 
The two designs will be identical in function. The main difference will be in weight. This is because of custom tubing being used.thaflyinfatman said:

I didnt search for the previous info, but here's some quick info on the dw-link.
The edge bikes are apparently designed to mimic a concentric BB pivot bike as explained by their web site.
The dw-link uses a tuned anti-squat profile which has absolutely nothing to do with a concentric BB pivot.
It is easy for onlookers not well versed in suspension kinematics and dynamics to look at ANY highly coupled link design bike (such as dw-link, Karpiel, COrtina, Santa Cruz, the edge, azonic worldforce, etc...) and lump them all together. The fact is that tiny variations in link arrangement can make HUGE differences in performance!

hey, if you know of any discussions on other forums that I should be a part of, by all means let me know, i'd be psyched to participate!
Will the new frame be available through Supergo?
They are my local IH dealer.

Why is'nt this bike an Evilbike???
If it was, I would buy it right away

The Taiwan welded frame is made from high grade 6061 T6 tubing that was custom shaped and triple butted to our specification. All of the frame tubes are custom and proprietary.thaflyinfatman said:
The USA frame uses a proprietary aluminum alloy for the tubeset. This alloy has about 135% the strength of 6061 T6 aluminum. Using this material let us cut down on the wall thicknesses on the custom triple butted tubeset used on the taiwan bike. The end result is a a USA made frame that is both stronger and lighter than the already really strong and light 6061 T6 Taiwan frame.

The complete bikes will be available through Performance and Supergo. As far as I understand, for frames, they will only be available through Supergo as a special customer order. You can definitely order one thorough your local Supergo shop. I definitely woud not expect to see any type of aggressive pricing on these completes.
Later!

Don't take this the wrong way but I am always leary of companies who claim to use proprietary alloys. Lots of companies have been alloying aluminum for a long time. If it was so easy to make an alloy that was 135% as strong as 6061, why wasn't it done years ago? Why wasn't it developed for airplanes? I have been working in the bike and metal industries for years and new stuff doesn't come around often. I'm not calling you a liar. I'm just asking you to shed some light on what you mean by proprietary.dw said:
proprietary means it's some alloy easton developed and wasn't able to sell it to boeing so they found another buyer... I'm almost certain that there's a better alloy out there but the cost would be too high for anything less than a space shuttle, either that or whoever originally bought the rights to buy and sell the alloy isn't willing to release it to anybody else.
There is a lot of research going into new alloys for aircraft. 3/2.5 Ti was developed to be drawn into 737 fuel lines. This opened the door for Ti bikes. My point is that I don't think there is enough money in a couple hundred DH frames to warrant a new alloy. There isn't much margin on a DH bike using stock tubes. If this alloy is so great, how come Boeing isn't using it.Kornphlake said:
The alloy is commercially available in the same way that scandium alloys are available. The alloy that we have chosen has been proven in automotive, sporting goods, and airframe use for years now. Basically its all good, and in theory, anyone could use the alloy as long as they can afford the cost of building a few thousand kilos of it into proprietary tubes. Obviously this takes a lot more capital than most bike companies have, but the way I look at it, if you have the $$ and the commitment, there's no reason not to explore your options.buildyourown said:
By proprietary, Iron Horse means that they are just not sharing the alloy # or alloy structure with people who dont need to know that specific info.
All that needs to be known is that the bike is light and strong!
hope this sheds some light on it!

Lucky for us, these are nothing even CLOSE to stock tubes!buildyourown said:
Being that you dont know what the alloy is, how can you be so sure that thye aren't? Heck, I developed the tubeset, and I dont even know if Boeing is using it! I am sure if they wanted to use it, they could. They are a big company!
dw
That makes more sense. Saying that you had the tubes custom drawn out of a commonly available alloy sounds much more feasible.dw said:The alloy is commercially available in the same way that scandium alloys are available.

However, I hope your not forgeting about the soverign with all the buzz about the DH bike. That's the one I'm waiting for.
Well, I wouldn't say its commonly available, but it is available for the right price!buildyourown said:
I m not forgetting about that Sovereign, believe me! Actually, I just talked to our builder about 2 minutes ago. Production tubing is landed in the US from the UK, machined parts are built, and with any luck we'll be on pre-production samples in a couple weeks! Things are moving smothly, just have to keep on top of it!

I am happy w/ my v-10 right now, but I'm thinking that a light DH bike that pedals like a maniac would be PERFECT for an agressive trail bike.
DW, how well do you think that this bike would work with a z150?
Shoot... what a sec. No front der. Will an e-type fit? What about a rhollof? too heavy?
I'm imagining this bike with a DH tubless rim in back and an XC tubeless rim in front... a z-150 to give some good travel but also to add a degree or so to the HT angle (about 68-69 ideally). Light components... single ply tires... and one of those double telescopic Titec seat posts.

Why wouldn't you just buy the DW-Link FR version-BB- said:I am happy w/ my v-10 right now, but I'm thinking that a light DH bike that pedals like a maniac would be PERFECT for an agressive trail bike.

The frame will not at this time accept a FD. It is designed specifically as a DH race chassis. The FR version will of course be completely FD compatible.
The DH frame is designed around approx 570mm length forks.
For reference in the singlecrown FR fork category:
Marz 666 150mm travel published length = 575mm.
Sherman Breakout + 170mm travel = 552mm

Any pics around of the FR version?
Will the FR version come in both Tube configs? (US and Tiwan)
Eh I just picked easton, it could be any manufacturer that came up with the alloy. My point is that you didn't create the alloy, but spec'ed it and had it drawn and formed to your specifications.dw said:
I meant to speculate what you so eloquently explained "anyone could use the alloy as long as they can afford the cost of building a few thousand kilos of it into proprietary tubes." So it's really just an alloy that is controlled more by economic factors than patents and such.
It would be heavier than the Olsen twins as well...squarewheels said:
