probably a repost but I was just browsing my images and I was reminded how ghastly this thing really is

I see your Poultrygeist,
n raise ya a Birdemic.

OOOOOO I'll have to check that one out

Has anyone had a look at what this hub does, or how it does it?

I'm currently trying to procure one for my work project. Would like to get hands on with it.

Will post if I get any info...

I'm surprised this hasn't been in a rap video! It's certainly tacky enough

really want to see this.....

Aluminium will usually fail before carbon as carbon is more elastic

Aluminium will probably fail first but your reasoning is wrong.

Sorry but it'sthe other way round, Aluminium has much lower modulus of elasticity. Basically this is a measure of how much force it takes to extend this material.

Carbon also doesn't really have an elastic deformation region at all, unlike aluminium where you will see the material stretching before it breaks completely carbon will reach it's fail point and then do so with little warning.

Why would the reaction arm cause a problem when the wheel has been flipped?

I think I understand why it could cause a problem normally trying to unscrew itself, but with the wheel effectively turning the other way would it not just think it was free wheeling???

Do flip flop hubs with a backpedal brake on the freewheel side exist? If so could someone point me in the correct direction please?

It's going well thanks, still in the prelim stages at the moment but we're getting there. Will hopefully be able to put some details up about it soon.

Just interested in the mechanics of it.

3 gears is getting a bit messy, like I said though just investigating the feasability of it

This is a bit out there (just sort of looking at feasability)

but could you combine this with a flip/flop?

What's with the trawling of old carbon fibre related posts dude?

Carbon's a bit of an interest of mine. Well alternative and exotic materials as a whole really

good post!

and yes prepreg is heat activated, you need to store it in a chiller.

I'm curently involved in the design and development of a carbon frame, this is good food for thought thanks.

Carbon fiber is light => saved grams
saved grams => I can eat more pies

I like pies.

fixed

mmmm pie

Carbon doesn't have the same multidirectional strength that metals do, it is more like wood in that respect = load it the wrong way and POP

Carbon is recycleable to an extent, but it does take a lot of energy again so it's maybe not the best trade off.

It should be stiffer and more accurate than steel/ali but once it fails it fails, there's no elasticity that you get in metal.

Personally I don't think it'll make a massive difference for average riding.

ding ding ding BINGO

Oh this is shameful! I can kind of see where they were going with the mathing colour scheme etc but it looks like it might have been assembled in the dark maybe...

The seat is far too low and what is up with the handlebar?

interesting, very very interesting....

cool, good list thanks

I think that could find a place in the market.

Chains just have the advantage at the moment because they're established already.

I think it makes an interesting commuter alternative?????
