Designing New Parts

[AlexxRogers]

Alright,

So I was thinking about some things along the lines, of opposite disc forks, so for people who side hop to the left, and want to run front disc, can do so without the worry of bending their disc.

Then I would go on to expand on this, by making frame with opposite disc mounts, then obviously, a rear hub and cranks for this set up to work properly.

Disc protectors could be another option, for people who do not want to spend the money on changing their set up, but also having some sort of protection on their disc.

Please tell me your opinions on these ideas, and let me know of any other new part designs that I could draw up and maybe go on to create one day

Thanks,

Alex.

Look at some triton frames, ive seen a few with built in disc pretectors.

Yes, but frames that don't have them, could have them like bolting on with the calliper.

Excellent idea. especially the fork. The frame would probly end up being to much of a gimmick to last long, but its good that people are thinking of new things. A bolt on rotor guard is a great idea!

Had a go at doing a quick design for one that would maybe go onto the axle before the axle nut, but it is limited to the rear only. Oh well, here it is:

Would it work?

That could definitely work, problem now is snail cams, most frames run them on the inside, and you wouldn't be able to run one on the left side, that's why I was thinking about bolting on with the caliper.

I meant t to go on the outside of the frame. I was looking at the new Onza Pro on Tarty when I designed it so did it on that. Will see if i can do something to the design to change it to bolt onto the caliper

Ahh right, wouldn't work on my Echo though

It's nice having options though.

Thanks for your input.

No problem. I am just drawing up a quick sketch of one now so I'll get it on within the next half hour.

How about this sort of thing. Maybe it's manufacturable if you could fnd the right stuff, but as to how it would hold up the arm does look pretty thin

There would be holes in the top arm that fit the disk mount, you would just need longer bolts as it would go through basguard->Disk tab->Caliper

That's much better dude, I could work off that tweaking the design, to make it stronger, and lighter, if you don't mind me using it?

Thanks James, big help dude!

...and a sprocket, and a freewheel. Not easy.

For the disc protector, I know of another company currently looking into developing one but because trials frames vary in design so much it's pretty hard to get it to work. To see that you've only got to compare the mounts of, say, an Echo Lite to those on a Red Sky. So many differences in size, shape, width etc. that it makes it pretty much impossible to come up with a design that works by bolting onto the mounts.

Can u not just f**k about with say a tensile and turn everything around?

I suppose so, but maybe a protector that goes on the fork would be feasible, as that would only require two designs in total, one for post mount and one for the other which I can never remember what it is called, (IS?)

Just an idea.

If you wanted to screw your freewheel back on to your cranks every time you put any pedal pressure on it I guess you could...

[Matt Vandart]

Oh yeah,

The chances of hitting a disk and bending it so much that an adjustable spanner wouldn't fix it, will not be worth the added costs of making 1 off component parts to protect your disk.

The forks could be mass produced though, as in a small business like fresh products maybe?

Just some ideas at the moment, as I have no tools, resources nor skills to engineer the products.

Mass produced? I'm not saying its a bad idea and it has no potential just as you said, you have no experience, no tools, no resources, and no engineering expertise. And your planning on mass producing forks to solve a problem which doesn't really exist? The only way you really bend a front disk is on a rock if your a natural bum boy, having it on the other side won't make it any better. And if your that concerned about hitting your disk anyway, just get a magura, its not like their aren't existing solutions to the problem that you fabricated.

Look at some of Alex Darks products he has offered the forum before (although he has the skills and the resources to make the products) if you follow the kinda shit he's doing you might actually sell something. The small company's like Fresh products and carbonique did well before because they found something every rider would want and then made them. I don't think that the trials world is crying out for a disk protector, LHD, or right side braking disks.

This is all constructive criticism in a concise manner btw,

Not sure if it's been mentioned, as I didn't read the whole thread, but mounting discs on the opposite side will just lead to weight distribution issues, no? All the weight on the driveside…

Hey let's design a left hand drive side!!

[Skoze]

You do realise you'll need to have the mount on the front of the forks like the new Pashleys, right?

Some people really don't seem keen on those, mainly aesthetically admittedly, but it's something to consider.

It's not just aesthetic, if you run a post mount style brake (avid with the post adapter etc) then all that is holding the brake from normal rotational forces are the threads in the mount and on the bolts.

[N.Wood]

Personally I'd say you're trying to solve a problem that doesn't exist.

I sidehopped to the left for about 5 years with a disk, and cant ever remember thinking I needed a right hand mounted rotor.

The past three years I've been sidehopping to my right and my left in equal measures and have still not come across a problem.
