slimline/slimeline why??

I'm a bit puzzled by the references to slimline frames as "slimeline".

I think that's probably down to some computers spell check, as far as I know both frames have the same geometry and handle the same.

Hi.
Norton Twin Restoration, by Roy Bacon, gives frame head angles Manx 26 Deg, Wide-line 26 Deg, Slim-Line 24 Deg, 750 Commando 27 Deg, 850 Commando 28 Deg,
Wideline frames use a longer rear shock absorbers and different length swing arm to the Slim-line.
Personally I think the leg position ( road bike ) would be set by the width between the foot rests and the width between the knee grips on the tank. I have ridden both.
Regards Craven.

The area of the inside diameter of the tube and the outside diameter of the tube both have a bearing on the ability to resist bending and torsional flexing.More accurately,it depends on area squared and the difference between inside and outside values.IT'S NOT ROCKET SCIENCE OR MAGIC.
*For a given weight of tube,increasing the inside and outside diameters will help rigidity.There is a limit to how far you can go with this;the tube will buckle easily if it becomes thin like a beer can.
*For a given outside diameter,decreasing the I.D. which means INCREASING THE WALL THICKNESS AND WEIGHT,will ALWAYS INCREASE RIGIDITY.

And going to a slightly larger tube diameter will increase stiffness, considerably.

slimline/slimeline why??


Going to bigger tubing, like the monster backbone in a Commando frame for example, may not always be possible, however...

There was considerable discussion about that 24 degrees for slimlines here a while back.
It is quoted elsewhere that all featherbeds were 26 degrees.

Hi
As we can see from this thread that a great deal talk about the construction of the frames and the possible effects on handling, but I would think that a fundamental difference in steering rake and may be a change in wheel base, weight distribution, was pretty important.
Perhaps my Slimline measured (roughly) at 24 Deg is an odd one out; hence my query if anyone could confirm the alleged difference.
Regards, Craven.
