Someone requested that I do a tech column on head angles and steering geometry. I wasn’t sure at first if this was a worthwhile subject, after all, there isn’t that much variation available is there? Most frames have a head angle of 74 and a half! Degrees and most forks have one and a quarter inch legs with dropouts that stick out just enough to get a peg on.
Granted the odd frame has a 74 or 75 degree head angle and there are so called “flatland” forks that have less rake but by and large they are all the same… or are they?!? Dun-dun-durrr (dramatic/sinister drum roll).
