Banshee Amp - New DJ

Wednesday, November 28th, 2007

Banshee Amp

It’s not-a-spy-pic of the Banshee Amp. We have listened to you and we’ll do the Amp raw with no decals at all. We’ll throw a bunch in the box and you can decide if and where to put them. You could spray paint the frame if you want and apply the decals after or keep it raw.

However we will put “banshee” on the inside of the non-driveside chainstay so you can keep it low key but people can still notice that you’re riding a cool frame and not a POS.

ISCG Tabs still to be welded on the frame.

We will be stocking a full range of spares and will be offering full servicing and rebuilding off all Industry Nine products. We are still getting spares pricing…but it will run similar to our surcharging structure (and the way we run spares on our other brands)…that is essentially cost price. Neither ourselves nor the shop make money on it, it only covers GST so we can give you the best possible price on spares to keep your lovely products rolling along smooth as a baby’s bum…as cheap as possible.

Our first Demo sets have just landed at the Airport and we expect to receive them today or Monday. You shall these featured and reviewed in magazines in the coming months and hopefully a review sooner on Farkin.net of the DH set. Keep your eyes peeled on XXIV.com.au as we will have an in depth look at the wheel sets we received, including internals and also have them strapped up to the first 2008 Banshees that we will be receiving next week.

We are still looking for dealers in all states for state exclusive deals for the first 12 months, so if you are from a shop or know a good shop then be sure to get in contact with me.

XXIV Appointed Exclusive Distributor for Industry 9 Componentry in Australia

Tuesday, November 13th, 2007

Industry 9 Components

It gives us great pleasure to announce that XXIV will be exclusively distributing Industry Nine Componentry within Australia. Industry Nine are based in Asheville NC, in the United States of America. It was in this rugged mountain bike landscape that Industry Nine combined solid engineering with stunning aesthetics to create a range of wheels like no other. Industry Nine outsource only their rims and bearings, everything else is precisely designed, tested and manufactured in house; a refreshing change to the continuing trend of companies going overseas in pursuit of higher margins. Industry Nine wheels excel above their competitors in 3 ways; weight, precision integration, aesthetics and customisation.

While the 7075-T6 spokes have similar tensile strength as a 14g stainless spokes, they weigh about the same as a triple butted spoke. The aluminium construction offers significantly improved lateral stiffness over any butted spoke. Also with the elimination of the nipple, the rotational mass of the rim is reduced. The spokes come in 3 different thickness to suit varying applications. Who else offers an off the shelf 1400gm disc wheel set with strength and lateral stiffness that rivals of exceeds any XC race wheel?

The Industry Nine spoke design eliminates the 2 stress risers inherent in traditional hooked steel spokes; the J bend and the spoke/nipple interface. Instead the spokes thread directly into the hub shell with a larger diameter thread than the main spoke body, eliminating weakness at the thread. This allows an increase in surface contact area by more than 200% over a standard 14g spoke and nipple combination. The sample simple theories were applied to the one piece axle assemblies, less interfaces means more durable parts. Another notable feature concerning precision is the engagement mechanisms. The patent pending mechanism offers a 3-degree engagement, far less drag than the competition and the ability to withstand over 700 ft lbs of torque! If you need a drive mechanism for your new Formula One car, look Industry Nine up!

Industry 9 Components

Industry Nine wheel sets are the most versatile on the market giving you the ability to easily convert your axles to suit your next bike. The front hub set can be converted to Quick Release, 20mm Bolt Up, 24mm Maverick Bolt Up and 25mm Specialized Bolt Up! Not to mention there is a Lefty specific hub available too. The axles also roll on only the finest quality Japanese ABEC 5 sealed bearings; providing superior seals to give a longer, smoother lifespan.

A primary focal point of an Industry Nine wheel set is the striking aesthetics. From the edgy design of the hub shell, to the custom color options, to the limitless rim choices; we ensure that your wheels will look as good as they perform. In house manufacturing allows Industry Nine to make spoke lengths to fit any rim. It may take a little longer to get but you can ride the rim you trust. Industry Nine is also able to do custom color hub and spoke combinations, alternating colors, fades, etc. If you can dream it and your wallet can handle it, Industry Nine can do it.For more information on Industry 9 wheels please visit www.industrynine.net.

Banshee Legend Frame Animation

Tuesday, November 13th, 2007

This is a little animation showing you the legend and going through its travel. The video got a little squashed so it looks shorter than it is (this is a large featured in the animation), it also makes it look like it has 10″ of travel when it really is 8.5″

Here are some further comments from Keith (Banshee’s Engineer) on the suspension system used mad on the Banshee Blog:

Why did I chose this linkage design?

Over 2 years ago, I was starting my final year of a masters in mechanical engineering degree and had managed to arrange for my thesis to be designing a DH race Bike for Banshee (I knew the Banshee guys already for a summer working with them out in Vancouver).

I wanted to come up with something new, but was not prepared to design an overly complicated linkage that had to use marketing gimmics to sell it (like some bike companies seem to resort to).

Firstly, I took into account all the aspects of the design that I felt were very important for a DH race bike, such as having a high strength and light weight design with a very low centre of gravity, and race geometry with low standover etc..

Once I had sketched loads of different suspension linkage options, I finally settled on this system, as all aspects of the linkage (such as axle path, chain stretch, leverage ratio, force interface, angular rotation of rear triangle, instantanious centre, centre of curvature etc etc) are highly tunable, and with the shock just above the BB, the centre of gravity is very low in the frame.

The next stage was to work out a way of fitting the shock and pivots into the system, this is where I started to design the forged shock basement to not only fit all the parts together, but to do it in a very lightweight and strong way that removed welds for the areas of high stress.

Then it was a case of doing hundereds of linkage itterations to find the pivot and shock mount loactions that would give the best possible suspension characteristics for DH racing, and I also spent a lot of time comparing my linkage performance with many other top DH bike designs to ensure that on paper the legend suspension out preformed them all.

Once I was happy with the linkage (which took 6 months or so of hard work!) I started to do the 3D modeling of the frame with detailed stress anaylsis. again there were a number of design itterations with redesigns to reduce high stress regions and reduce material where there were low stresses to save weight. I also wanted to keep clean lines and simple but efficient aesthetics trhought the frame design.

This has been going on for about 18 months on and off to achieve this model, and once the prototypes are ready, then I am more than prepared to carry on the improvement process to refine the design further with yet more feedback from racers and test riders. By the time the first 50 frames are released to racers around the world the frames should be dialed, but I will still be asking for yet more feedback and ideas to improve the design even more!

We are treating the Legend as an engineering and design project, with the aim to give our riders the best possible tool for the job. We ae not going to be making money on the Legend as it is costing us a lot to manufacture and develop. People might find this weird, but personally I believe that the flagship model of any company represents the whole brand. And as we are a ‘new’ Banshee, we have to show people how our design ethic has changed, and preformance has improved to meet and exceed the customers expectations.

As for how this linkage is different and preforms compared to other systems:

Horst Link:
Horst link linkages are used almost purely to maintain active suspension under braking. They achieve this well, however there are several downfalls of this design. The axle path tends so be vertical to forwards, which is very bad for square edge bumps, there is no real chain stretch, which results in poor pedalling efficiency compared to other designs. Also the assembly is structurally weaker than many other designs due to the non triangulated rear triangle and the horst pivot location. This results in a weaker design with more lateral flex for a given volume of material when comapred with just about any other linkage design.

VPP:
This is a highly tunable design much like the legend uses, however there is one magor difference! The ‘VPP’ linkages use 2 short links that rotate in opposite directions (watch a video of the suspension working on a V10 to see this), this results in a rear triangle that rotates even more than a swing arm on a single pivot, and so has a major effect on suspension performance under braking unless using a floating brake adaptor.

Legend:
Uses a short link 4 bar suspension design like the ‘VPP’, but with links that rotate in the same direction. This means that there is potential to adjust the pivot positions and geometry of the linkage so as to adjust the system characteristics. This is exactly what I have done, but I have also minimised the rotation of the rear triangle to have active suspensio under braking, and also kept the shock extremely low in the frame, (lower than any other frame design that I can think of).

Banshee Legend - DH Race Bike, Light and Fast….Yewwwwwww!

Banshee Legend Mockup

Remember this moment; the public launch of what will prove to be one of the best DH race bikes the world will ever see, you could say it is the birth of a Legend!

After over 2 years of development, study, analysis, calculations, consults, and multiple redesign iterations, I am very proud to give you your first glimpses of the Banshee Legend MkI DH race bike.

Banshee Legend - DH Race Bike

 

The Legend MkI is the flagship for the new improved Banshee. This bike is made purely for DH race, and that is reflected in the geometry, weight and performance.
Coming from a clean slate, the Legend MkI has been designed for one thing… to go fast! Every aspect of the frame has been meticulously designed to be light [8.5 - 9lbs] and low.

Having a low centre of gravity on a bike gives it more stability, especially at speed, and makes the bike much easier to lean into corners and tear around them.

Banshee Legend - DH Race Bike

 

One of the best ways to keep the center of gravity close to the ground, is to place the shock (relatively heavy, especially with the 3″ stroke shock the Legend MkI takes) as low as is physically possible in the frame without leaving it exposed below the BB. The legend has achieved this by enclosing the shock in a machined shock basement forging which allows the shock to effectively go where the down tube would be.

Banshee Legend - DH Race Bike

 

The shock basement is designed to be the lightest possible way to achieve the low shock positioning, but it also is an incredibly strong design for its weight. Since the shock basement is 2 side forgings welded together down the centre line, this means that there are no welds at all taking the high loads of the rear suspension linkage. As we all know, welds are the weakest part in any frame, so by removing them completely from the high stress areas we can achieve a very good strength to weight ratio.The linkage is a specifically designed to be the best preforming DH race suspension system available on the market today (according to data, calculations and performance graphs). This has been achieved by carefully manipulating pivot positions and linkage lengths to optimize such factors as leverage ratio, chain stretch, pedal kickback, force profiles, rear triangle angular displacement, axle path, instantaneous center, center of curvature and many more characteristics.

The results of the thousands of iterations and calculations, models and remodels is a linkage that will enable the fastest riders to go faster!

Banshee Legend - DH Race Bike

The Legend linkage exhibits:

  • Adjustable travel between 7″ and 8.5″ with self adjusting geometry
  • An initially rearward axle path for small square edge bump sensitivity
  • Initial chain stretch of which the rate diminishes as the suspension compresses deeper into its travel, to improve pedaling efficiency, while limiting pedal kickback
  • A progressive to linear leverage ratio which will results in a highly efficient pedaling platform
  • Active suspension under braking
  • Ultra low center of gravity and BB height
  • Lateral stiffness to ensure that the power from the pedals goes straight to the back wheel rather than frame flex soaking it up.
  • Cold form extrusion link and shock actuator
  • Bushings instead of bearings

With the same style internal grease injection pivots used in the VF4B frames combined with large diameter advanced polymer bushings, result in a supple suspension linkage with great performance and ultra low weight, whilst keeping the maintenance simple and cheap.

Banshee Legend - DH Race Bike

 

The Legend Mk1 also has a Banshee propietary custom triple butted hydroformed tubeset which result in large weld interfaces and integrated gussets, as well as the internally ribbed chainstays and seatstays that Banshee is famous for.With a 150 x 12mm maxle compatible dropouts the backend will be stiff and quick to change a flat if required to.Chainline is dialled with the 83mm BB shell and integrated ISCG 2005 standard for chainguides

The 1.5″ head tube allows our riders to either run the new generation of 1.5″ stearer forks, or to run a zero stack reducer headset to keep the front low.

Banshee Legend - DH Race Bike

Again, the estimated frame weight without shock should be around 8.5-9lbs, but we will have to weight til the prototypes are ready to weigh them accurately. This bike will only be available in limited number to DH racers for 2008, so apply now for a chance to get your grubby mitts on one!
