when riding on a brompton, i felt a harsher ride compare to my downtube mini. everytime i go over cobblestones, small pothole, i really feel it. is there any particular reason for this? both are 16" wheel and the only difference is my downtube mini has a suspension at the rear while the brompton just has a solid block at the rear. is it the thin marathon tires on the brompton? the downtube mini tires are kenda 16" x 1.5" and look a bit wider than the brompton tires. or is it lack of suspension on the brompton?
for those ppl that own the brompton and dont like the "bumpiness," what do u do to correct this? do u get a spring brook saddle like this one?
and does it really helps?
the rear block that i'm talking about look like this rear block that i rode on:
would getting the newer rear block like this one help also?
thx in advance.
