The angle of the steering head is not adjustable(correct) but Raising or lowering the front/rear changes the rake angle and therefore we have effective changed the angle of steering head which in turn changes the trail. The important word being effectively.

Unless you get some Spondon adjustable yokes.

To do what? Adjustable yokes won't change the steering head angle.

Err yes it will, they have some yokes where the top part of the yoke can be moved forward and backwards to change the angle, there is another set of yokes where there is a rotating adjustment on the yoke stem and it can be changed.

Err have a look at these harris ones http://www.harris-performance.com/we..._Yokes_10.html

Wrong again :P :wink:

What adjustable yokes do is change the yoke offset which in turn changes the trail. means you can vary the trail for rider feedback, turn-in etc without effecting stuff like rake, swinging arm angle etc.

You could fit different bearings in some sort of spacer arrangement, with a smaller stem...

Ok, you can still do it but they might be called "Raked Triple Trees", they still come under the guise of Adjustable Yokes, just harris dont have them on their site.

I know what you mean but that is not adjustable yokes as we know it :wink: . Harris won't do them as they do stuff main for proper bike innit
:lol:

Those things only worth mentioning if you start talking about choppers and the like and even then if my memory serves me right most builders there are questions about forces acting through said yokes.

You could also in theory change rake angle by boring the holes in yokes for the forks at an angle and infact think of it one or two manufactures have done that.

So all told except you like choppers etc/have a bike with adjustable steering head you won't be getting any yokes of the shelf to change the rake angle. The only other way is to raise or lower the bike.

suspension adjustment
 

OMG I have never seen so much quoting! :)

Anyway! I went for 20mm and took the bike for a spin earlier, I tried jabbing the breaks and feeling for some kind of metal to metal contact or anything out of the ordinary and all seems well.

Early indications for me are a fantastic improvement but I would expect that given ive jus fitted decent rubber, progressive springs and stiffened up the back. Im going to Skelmersdale tommorrow (it has no traffic lights and tons of big roundabouts) and im really gonna give it some and see how it performs, that said I can already tell it is an improvement and ill never change any of it back so im made up!

It is rake by the way :twisted:

I'm not going to swear by this, but I'm about 90% sure that 20mm will allow hard impacts on full compression- braking's not a very good test of that, since even with squishy SV forks you get bigger compression on impact. Go and nail it over some speedbumps, see what happens :wink:
