Is This Linkage Fork the Future of Suspension? - Crankworx Whistler 2017
@sq225917: I'm not saying it will be any better than current designs. I'm just saying that there is a chance this might be a good idea. Some people are forward thinkers, others are sheep. Forward thinkers are often wrong, but at least they try something. If everyone was like you, we'd still be waiting for random lightning strikes to start our fires for us.

Is This Linkage Fork the Future of Suspension? - Crankworx Whistler 2017
@sq225917: Ever stop to think that the reason there are no linkage forks in MX is because the linkage needs to be similar to this one to work effectively? If we're going to look at absurd comparisons to MX bikes let's go a little further. Why do we bother with more complex rear suspension designs when all motocross bikes are either linkage driven single pivots or direct-mount single pivots? Why do we not see water bottle mounts inside the frames of dirtbikes? Why don't mountain bikes have ultra wide rear tires when compared to front tires? Why do we bother with handlebar shifters when clearly foot shifters are more effective in MX? What I'm getting at is that you clearly aren't thinking things through to their logical conclusion. Yes, dirt bikes are the motorized cousin to mountain bikes. But there is enough different about them that direct comparison is silly. Also, one linkage is not equivalent to another and to suggest that "any old linkage" should be considered shows an obvious lack of understanding in basic engineering principles.

@elias15: All you are doing is speculating based on what you think is the case. As an engineer you should probably have a healthy respect for product testing and results based analysis. It may not be able to handle the necessary torsional loads or it may surprise you. I don't see a whole lot of difference between the length of the front linkage vs that found on the rear of a bike, however I do concede that the front of a bike sees different force vectors than the rear. I may be a lowly geologist, but my father is a mechanical engineer with several patents to his name with respect to designs for cantilevered actuators and hydraulic lifts who sees no major challenges in creating a system that shows very little loss of stiffness in the vectors that forces are expected at the front of a bike when compared to a traditional telescopic fork. Keep in mind, longer forks are more flexible than one would think. The major loss in stiffness would be along the longitudinal axis of the bike, not the rotating axis of the steering system. Wheel deflection on a 29er would produce similar loss in stiffness when compared to a 26er and they don't seem to have insurmountable handling characteristics.

This argument is ignorant. There is no room for a linkage like this in a motocross bike because well, they have to fit a radiator, fuel tank, exhaust system, airbox and an engine where this linkage would reside.

I replace the pivots on my Wilson and Troy every year. Costs me $25 in parts and about 30 minutes for each bike. It isn't a big deal to change bearings out. A good bearing punch/press will set you back about the same as a proper seal driver will for a telescopic fork.

@elias15: Their linkage forks are on their off road enduro bikes as well as highway cruisers. But there is even less room on a motorcycle frame for this type of linkage than there is on a MTB frame so it makes sense that it could be pioneered on bicycles rather than motorcycles.

Am I the only one who actually think this thing looks cool as fuck? Yeah, a little out of the box and will need some serious development. But I would pay good money to take that prototype out for a ride on my local trails to see how it compares to my trail bike. Also, this goes out to @Structure-Ryan, would I be correct in assuming that despite the lengthening of the front-center the axle path is not actually forward with respect to an impact but rather neutral and it is only the motion of the front wheel with respect to the frame that causes the lengthening of the front-center?

Prototype Hayes DH Brake - Crankworx Whistler 2017
I don't know man. I'm not a huge brand loyalist, nor do I typically get on the hate bandwagon. But the last 4 sets of Hayes brakes I've had were utter garbage compared to contemporary competition. I had the Stroker Trail, Stroker Ryde, El Camino and an HFX-9. None of them stayed on my bike for more than half a season.
