That set on a K model looks impressive, I wonder how they lock the legs to the hollow axle? And how much do they reduce the trail by?
I have had a similar problem with hard right hand corners, and have decided to add a stiffening brace, a bit like an incomplete fixed swinging arm to lock both leading legs/forks together to make it all more rigid and non–flexing. Seems to have worked quite well now.(see attachment).
Re. triple tree angle changes, Do you know of any who make ones with a 7 degree change in the USA? I’ve heard that they are available but can’t find them.
Also do you have the email address of any firm in England which make leading legs I had one but have lost it.
