I guess Kevin the chap who did a nut and bolt rebuild of has been my +8 for the last circa 18 years must have altered the suspension to some degree perhaps with multiple leaf rear springs for even while fully loaded while touring I have no recollection of a jarring experience over undulations..
It was not until I stumbled on this Plus Four road test vid that it seems some folk can experience ride issues in trads that seem worthy of attention..?
If you do not wish to watch the whole vid you can jump in at 7:20 and get ready for the jolt which seems to have come as a bit of a shock to the tester ?
