Best style of suspension?

[titch__16]

BTW, have you designed and built non-suspended bikes before?

Last year I designed a carbon road frame for someone and it was built. I haven't built anything myself and most of the fabricating will be done by a friend's father. The main reason behind uploading progress of this is to get some constructive criticism, because I don't know anything suspension tbh

how are you going to brake the rear wheel ?

the lefty righty stuff is all well and good, and cannondale and others
have done the front end very well ,but you need specific wheels
and therefore hubs for them
it all depends what your trying to achieve here
a uni engineering project or just dicking around on solidworks ?

whatever your doing keep doing it

In the picture of the rear left side there is a disc brake tab.

As for hubs, I have designed a set of single sided mounted ones, once they're loaded into this model I'll put a pic up.

And this is basically something in the planning stages as a personal project.



The reason for the 'lefty front righty rear', is I thought it may even any offset balance given by just a lefty front.

I'll work on moving the pivot closer to the stanchion now and get a pic up.


And one more thing, I'm not trying to 'reinvent the wheel' with this. It's more like putting ideas down on paper (or screens )

get it built

looking forward to progress/updates

Thanks, I definitely hope to build it at some point in the future.


So this is my axle design;

The round purple part is a cap with a splined centre, the splines fit over the axle then a bolt holds the cap on the axle.

why spline it? ,just adds to the cost
just needs to clamp the inner bearing race

a q/r would also be better than a bolt ,tho i can see the merit in a bolt

It shouldn't be too difficult to adapt this to a bouncy rear end??

This also is rather nifty...

It doesn't actually need to be splined, I just thought about it and realised it won't move with the wheel.
Also a QR system will be what I work on once the frame design is closer to finished. The issue I thought about with a QR is that the caliper will need to be removed before the wheel can be moved at all.

The only thing with that is that I'm using the left side for a disc brake.

So here is the new pivot placement.

It's novelty value certainly has merit...

Why does the disk brake need to go on the left side of the hub?
You've redesigned everything else why not the hub and disk mounts?
Like the picture posted above, have the wheel attach to the frame between the cassette and spokes and the disk mount on that with the disk on the posies side.

That would probably need to have a redesigned gearing setup too. Unlike my design the road bike is a single speed and mine isn't so having the cassette on the outside of the dropout would mean no derailleur. I could possibly put a sort of brake bridge and use a canti/V-brake, but I think the current design is simple enough.

Beefed up the chainstays,

There isn't a chainstay bridge, is it necessary to have one?

 

[gtRTSdh]

You have to join the chain stays very rigidly otherwise nothing (of any significance) willl stop the rear wheel leaning over to either side.

This:

a) makes single sided rear end just plain nuts.

b) where your pivot is, leaves no space to brace the chain stays.

So bring the pivot forwards & up to where the old Marin's have it and brake the chainstays together.

Apologies if I've missed the irony in this thread and it's a windup.
