Best headtube angle for old folder.
Could somebody tell me the best headtube angle for an old "R20 like" detatchable? Looks much like the famous R20, so I think they can be compared.
I am going to put a new fork and since I find the headtube (and seattube) angle wery "relaxed" I was thinking of cutting off approx 1 1/2 cm of the lower part of the head tube before cutting it to the right lenght for the new fork.
What makes me think twice is that I`we got a similar bike, only 24" wheels. I rode it for a short time with a 26" rear and a 24" front just to test out the lowered front. Found the steering "twitchy" and strange. What is the best angle for such bikes?
The purple bike is mine, but picture is not good,
Blue /green bike is not mine and picture is not mine but same type bike and better picture.
Brown bike is my 24" that I tryed with lower front to change angle.
What do you think?
