This amazing contraption is the result of HB having too much time on his hands at his ranch in Colorado - so much history on this set up.
Oakley's rolling booth travels around the country to various events promoting better optics for everyone.
Speaking of rolling around the country, Projekt Roam is the home to Jesse and Colt Maule as they travel around North America documenting riding areas.
45NRTH is another company that is all about cold weather and fat tires (they make a studded tire that is 26 x 4.0 in size), but it was their low-profile pedal that caught my eye.
Crankbros makes limited edition pedals for the Outdoor demo each year for riders to try out and purchase.
KHS had their 650B DH Prototype at the booth. KHS was a first-adopter of the mid-sized wheel and now expands their expertise to the gravity scene. The industry will surely be watching when it hits production.
The Nuke Proof Mega TR is aimed at the Trail, Enduro and AM riders. The TR is built around a 130-millimeter-travel frame and a 150mm-travel fork.
Ellsworth's Carbon Evolve is their 29er XC race bike, with 100 millimeters of front and rear travel.
The e13 LG1 Race and TRS Dual Race carbon guides in pre-production stages - the goal for this project is to create guides that are 70-percent the weight and 130-percent the strength of current LG1+ guides.
e13 LG1R (Race) cranks, 36T ring and LG1+ 36 Guide were looking fast just on display. This is the same set up that the United Morewood team runs.

Spooner009 - comma - ,
SuperSlowDH - Maybe he should,but seriously you could not read "wourld" as world ?
superbikes - i understand you perfectly and also agree totally.
Who knows something great could be revealed tonight! Or maybe marzocchi will just announce anodized purple and green forks and I will roll my eyes and go for a ride.
1+ this comment if you would purchase a high quality leatt style neck brace IF it was LESS than $110
If this comment goes negative, I'd recommended making the robotic fish fillet-er instead
I agree to the neck brace thing though they need to bring a cheaper alternative out!!
And yeah my neck is worth $300, but I don't have it, so I don't get that protection.
I don't need high quality, just basic function. It is not a question of quality, but availablity. I can find them for $60 which isn't terrible except that is what I paid for my helmet and I only would use it three times a year. I want one for $30.
I guess I'm just cheap.
there is a VERY good reason Shimano continue to make all of their cranksets, including their premium Dura Ace, XTR and Saint crankset from cold forged aluminium alloy
they see no overall advantage in carbon fibre for cranksets and there are genuine issues about impact damage (whether from rock strikes on MTB or clipless pedal shoe cleat scratches on road bikes)
Shimano is undoubtedly the master of bicycle component manufacturing technology - their product has a quality that SRAM and others simply don't have...and I have a lot of SRAM on my mountain bike!
Hit Fat jumps and drops with our new 1" Diameter Thick Stanchions supporting 120mm of legendary travel in a stable Dual-Crown Format. Also, New revolutionary 12" Tire Size, do more with these awesome tires!
26"? 650B? 29'ers? What do they all have in common? They SUCK! With our own propriety 12" Tire Size, you'll be able to fly Downhill while smashing those local grassy knolls and even Smooth Trails! AWESOME. Our unique geometry with awesome feature will make any nooby Rider into the next Sam Hill.
In any case, the only thing special about the pedals show is that they're a limited edition colour combination only available at Interbike. Its like the companies that give away / sell cool bottle openers or wallets or keychains. They're nothing most mountain bikers couldn't make themselves using broken parts or defective samples or something, but they're ëxclusive" because you got them at Interbike, so that makes them better....
I myself have made elaborate wind chimes using chainrings, cogs, and titanium seatpost shafts, bottle openers from pieces of cogs and spare chain links, drink holders from pieces of inner tube, etc.
How long do you think the industry will keep on with three different wheelsizes?? Next year you get 650b tires because they push them sooo much and thats it!!
I think all of that is a step in the wrong direction!
As to how long... the industry will keep supporting EVERY tire / wheel format as long as there is demand for them from the consumers. Right now Schwalbe alone makes tires for about a DOZEN different sizes of bead seat diameters. You seem to think bicycles start and end at 26"(iso 559) and 29" (iso 622), but there are a host of others not including just 650B (iso 584) and even 24" (iso 507).
They are just blanks ordered from Wellgo based off the B181 design and minor cut work done to "customize" them.
They will probably cost a good bit more as well!

nice packaging though....
I think it is just SILLY.
No one with common sense would go out DH riding with such an expensive and surface-fragile component.
Going back to my point - where is the common sense? I would reluctantly put carbon cranks even on my XC bike knowing how often I hit the stones and roots with them.
I like carbon as a material, I think it makes perfect sense to use it to produce frames, handlebars, spacers etc.
In my opinion, when comes to cranks, it is an expensive and fragile cosmetic treatment. Note that all those cranks have the aluminium core.
I guess if you are pro you do not care what the mechanic/sponsor puts on your bike, and if you have money and want to look like pro then you simply go for it, it's your choice, but not very wise, practical or economical in my opinion.
not worried bout the strength of carbon? what are you on about then?
one of the guys I know here in the UK is a carbon composite engineer for Williams Formula 1 racing, this guy is at the top of his game working on destruction testing and development of carbon fibre
he is also a keen mountain biker, and has openly stated (on UK bike forums) that carbon fibre is the future for frame manufacturing, but NEVER for handlebars, seatpost and cranksets - he would rather continue to use aluminium alloy bars, posts and cranks, with very good reasons..
@ Railgunner, guess what? I know the RaceFace very well and it's one of my favourite brand.
okay then. Let's hear these good reasons.
I use carbon frames and wheels, but never again for bars, and wouldn't for seatpost. Not thought about cranks.
"Why carbon?
Well let me be of some assistance. I have an MSc in the subject and work with it and test it every day at the top level (Formula 1). Are you sitting comfortably?...
Here's a brief guide:
For a start do not buy carbon bars for downhill or any kind of harsh riding!
Carbon composites are materials made by using a resin (usually epoxy) reinforced with carbon fibres, these can be continuous, as in woven cloths or unidirectional ribbons for example, or discontinuous short fibres or even nano tubes!
Pros:
It is light and strong and can be made into almost any shape.
Its strength can be designed into it in the desired locations depending on fibre placement and number of plies (layers).
It can be very stiff, or very compliant (depending on how it is designed and made etc).
It has excellent fatigue life (verging on the infinite).
It can absorb huge amounts of energy when it fails (hence great for making helmets).
It can be tough (depending on the resin).
It has excellent damping and shock absorption properties.
Cons:
It is expensive.
Its purely elastic nature means that it does not locally yield at points of high stress, unlike metals which relieve stress concentrations by deforming plasticly around the point.
It is not indestructable.
When it breaks in tension it goes with a BANG and without warning.
When it breaks in compression it crumbles (with a not so big bang).
When it breaks it splinters (health hazard, in more ways than one).
It is weak in any direction other than the fibre direction.
It can be brittle (depending on the resin).
"So you can see why they are not good for handle bars, where there are many stress concentrations with everything that is bolted to it. These can induce failure. Carbon composites are best joined by adhesive bonding, not with mechanical fasteners like nuts and bolts (see cons).
Now, Carbon Nano Tubes (CNTs) Not to be confused with Carbon Ultra Nano Tubes are minute (on the nano scale) tubes of carbon. Imagine a sheet of carbon atoms, one atom thick rolled into a tube. These are some of the stiffest and strongest (to weight ratio) fibres known to man. Hence if used correctly as a reinforcement can make some very strong stuff indeed. However CNT's are very expensive to make. Recent developments in technology have reduced the costs though and we can now see such technology in things like bicycle handle bars. However, still at a price of a couple of hundred pounds a gram of CNTs (or something ridiculous) I wonder how the likes of Easton make a bar entirely from CNT reinforced composite for the price of £70. I imagine they use a tiny amount of CNTs in their bars. Meaning the rest of the bar would likely be made up from woven carbon (as some of those photos suggest).
Carbon can be woven, with many different weave patterns, including plain weave, 2x2 Twill and 5 harness satin weave. The latter two are often used in structural parts and have good drape properties for forming complex shapes. Some woven fabrics however are used for cosmetic reasons, like plain weave for example. You can also have layers of woven plies.
The Easton bars use woven carbon for structural reasons too. They cannot be purely CNT composite - it would cost way too much! But CNT composites, if made properly with even distribution of the CNTs (which is the tricky part as they often 'clump' together being so small) will potentially be stronger than woven."
"Basically Alloy bars will be much more durable and much safer. Don't be a fool - don't put carbon bars on your bike!
I might add that carbon can be used to make ideal frames (Lahar for example) and some components. It just takes good design. Metal inserts bonded into the carbon structure are a good way to provide locations to thread / bolt to etc. However there can be problems with bonding Alu to carbon (thermal expansion and stiffness differences, galvanic corrosion etc). Titanium is really the best option here as it has none of the problems that Alu does...
Anyway if you've read this far - well done, I hope this has been interesting.
In summary: Don't buy carbon bars, waste of money."
yes, aluminium alloy bars can fail (anything will fail given enough load), however the modern, quality brand (Easton, Race Face, etc.) aluminium handlebar is very well manufactured and tends to bend rather than suddenly shear as myself and my riding buddies have experienced first hand.
in the "real world" the aluminium bar tends to be a lot tougher from everyday wear and tear like scratches / gouges, fitment of equipment (brake lever, shifter, stem, locking grips) and crashes where the end of the bar digs into the ground, compared to carbon fibre bars which are very "notch sensitive" and do not have the localised elastic deformation that an aluminium bar exhibits if the brake lever is pushed into the ground in a crash
I am thinking particularly of one customer at my old shop using an Easton CNT DH bar which suddenly sheared next to the RF Diablous stem on his next ride (causing a crash), following the previous crash where he put his left grip into the dirt.
We had fitted the bar in our shop, using torque wrench and checking his lever, stem and shifter edges for any sharpness before mounting the bar.
This customer was 12 years old and slightly built, the bar was approx. 1 week old and was actually a replacement for a 2 year old Easton EA-70 aluminium bar which was heavily scratched and gouged, having survived 2 years of abuse and crashes without any issues - let's just say his next bar was aluminium alloy.
