Some with stiffer upside down forks aren't TOO bad. But RWU forks simple flex and bend rather than go through their travel as they do when not so raked out. Sure they compress a bit, but they flex and deflect off bumps like you wouldn't believe. Go ride one.

Indeed - it is very simple vector addition. draw the picture.

the closer to vertical (or alignment with the compression force, the better the telescopic fork willwork because you reduce the "sideways" bending moment - this is what causes stiction as well as bending. Over the years the compromises to reduce it have been: larger, thinner walled fork stanchions. "Upside down" forks, better bushing material. Better, stiffer, sliders and better lock to reduce twisting (bigger axles etc).

If you can get hold of Tony Foal'e book. The maths is over my head but the pictures are hella informative.

All good mate. You know it too. Pay attention Drew!

[Crasherfromwayback]

How so? I did say that it's just my musings. The fork still compresses over bumps, they just have to overcome more friction because of how they're loaded on the guides. And they have to travel further than they would with less rake because the action is less direct.

What am I missing?

Here's a couple of pics for comparison. Which forks will react better to bumps Drew?

[jellywrestler]

It gets double takes. Twice. Ummmm...not surprised.

seems up for answering interesting questions too....

is this a forefather of you Drewpy?

I like the bumps on the ladys myself ;-) we know drew a 3 wheel man at heart not sure they have suspension do they ?
Mind you just as dangerous you end up pushing a pram doing house work omg i take the bike thanks if only i knew .
I gone to the shops i be 5 mins lol my 20 years have passed by opps

What of all things holy why whould want forks raked like that looks daft

Mind you can go to far with forks being like race bikes and be just as scary on the road.
Imagine a lawn mower with extended handle ,like that you hit a bump and bloody,and bloody well chop your own feet off.

I'm not sure what you've actually said there sorry.

Oh no ten lines

That makes two of us

Look. I'm not saying I want a chopper as my daily rider. I'm saying that a hardtail is not the most I'll handling bike out there.

Apart from bikes with mechanical faults eg worn out suspension, broken frame etc what type of bike in WOF condition do you think would handle worse than a hardtail chopper?

Classic Drewpy retraction when the heat comes on and he suddenly realizes that his babbling cant stand up to actual facts and pics from people who know..

You could always say "Sorry I was wrong" but I suspect you may not know how to.

Ever ridden a bike with a suicide shift?

But ya don't need a raked front to have a hard tail.

I'm not retracting fuck all. I was clarifying my point. There's nothing wrong with a hard tail. Apply as much heat as ya want.

do you even know what one is Drew?
