Does the slacker head angle make any difference to the handling … ?
lots.
yes i’ve ridden a 456, and i own a standard inbred.
the steeper head angle on the inbred/456 means i have to hang off the back on steep descents, to keep my weight between the two wheels.
the slacker head angle on the Ragley means i can maintain a more ‘normal’ riding position on steep descents. making it all a bit easier.
the Ragley head angles are completely normal if you compare them to full-suspension bikes, but for reasons that i don’t understand it seems hardtails usually have old-school-steep head angles.
consider an inbred, with a 70 degree head angle, ride it down a steep slope, the forks will compress another inch or so, you now have a bike with a 71 degree head angle, and a really interesting weight distribution…
