About 70% of my local slopes/mountains are unridable as current boards can't cope with the rough terrain. I'm not building suspension trucks to ride whats already ridable but to ride the unridable.

I think this is what brennig intends to do, not turn the gnarliest track in to smooth as milk track but at least make it rideable.

Just to clear that up for everyone.


A mountain bike has wheels with much larger diameters. This makes a big difference going over rocks etc. relative to 8-10" diam wheels.

I'm no expert on suspensions, but I'm sure size of the bumps will make a difference.

i pretty much think thats the main reason suspension isnt worth it. even with all the suspension in the world we will never be able to ride over some of the terrain that bikes can. not to mention the potential for going wrong as complexity increases.

also ive always felt that 'feeling' the bumps in the ground through the trucks and your knees is what makes it possible to apply those tiny little changes as you ride in order to get that perfect corner or carve. im imagining suspension kind of blurring this sensation and i can just imagine catching on stuff as you turn more often because of it.

however id be right in there to give any suspension truck a go!

@Brennig - you must be a better man that I cause i cant imagine any way that i could ride down Craig y Deryn, at least not on the side shown in the pic. i take it you mean to ride the side you say is 20/30 gradient?

Yah the 30 side, it's like a big slope covered in bolders and drops, you'd have to weave in between them and carve and slide the monkeys out of it but I can imagine with suspension trucks it'll be possible.

The trucks I have designed at the moment have roughly the same amount of parts as a channel truck, maybe even less. Another thing to add is the adjustability, with such a simple design I can change, ride height, suspension resistance, steering resistance, camber, axle track, cornering camber, suspension travel, axle track, and probably a whole lot more that I haven't noticed yet.

Well it wont be long 'till I start building so I'm keeping it back till then. I'll be building two pairs of them, I could build another 10 trucks but I need some nosno axle stubs which cost a LOT, more than the rest of the materials combined. I'm building them to fit MBS/Trampa/skate hole patterns so it should fit anything expect nosnos.

Back to Kiwi's original idea, to make the suspension softer obviously use softer springs. But to keep the compression for turning, if the springs are moved further out and away from the kingpin, then the steering compression increases.

tasty man, will be interesting to transfer the trucks to different decks to feel the difference between super squishy freeride decks and hard freestyle.

Is it going to be individual wheel suspension like a car, or is the whole truck going to be suspended like in the idea here?

a nosno pro downhill on 10's has made it down several mountainbike world cup black runs in europe, rock gardens and all, and in the right hands (or should that be legs) very quickly.
Adding suspension to a board with that level of absorbtion already, in my opinion, would be pointless. 10" tyres run at 8-14psi depending on terrain are a very useful tool which serve a very similar purpose to a complex suspension system. If you can get away with more than 16psi in 10's you should have changed on to the 9's already, they are a form of suspension not a fashion choice.
The reason i moved into mountainboarding (nosno's more specifically) and away from bikes was because they are simple, solid and i was sick of my bike breaking every weekend. Adding complexity in my mind only serves to reinstate a level of frustration. In 10 years of riding, much of it fairly mellow but some of it at speeds your mother wouldn't like on silly terrain, i have broken 1 wheel bolt, 1 alloy axle, 2 kingpin bolts and 2 hubs. That is one of the best things about my riding experience, the solidity and simplicity of the kit.
Jasper - you mention suspension on a hardtail bike making things rideable. Yes, this is because it it for your front wheel which is controlled by your hands, not your legs. You don't have the same absorbtion capacity in your wrists and elbows as you do in your knees. A short-travel rear shock and rigid forks wouldn't open up terrain in the same way.
I think this is over engineering and i think it is trying to solve a problem which doesn't exist but i am a nay-sayer. NAY!
Love the projects though and i look forward to you telling me to fuck off when you prove me wrong! Innovation is always met with hostility, and today i shall play that part and i hope it will serve as some fuel to the fire.

Yeah but you're one of those nosno peoples who managed to find themselves on the internet, you'd strap a boulder to your forehead if you were told it would make you faster.

Or maybe Chris has enough riding experience to know whats going to work or not work...

Don't forget some of us on here have shitloads of experience in "extreme" sports outside of mountainboarding as well as within the sport to draw on when they say things, so to dismiss them like that is somewhat arrogant.

Probably, but I have exams coming up and I'm looking for any excuse not to revise. Made a prototype yesterday, seems to be silky smooth, no bump steer and they manage to turn. Might try and build them within the next few weeks, just a few issues with return to center but that's probably because I'm using elastic bands, swapping them for some tension springs should do the job. I don't think a lot of people understand what these trucks are going to be like so I'm just going to keep back in till they're finished, they aren't going to be some overly complex space rocket precision trucks.
