i know how it would work out. on a frame that isn't really stiff they gonna bounce all over the place and probably get scared and slow down at about 130rpm.
one of my bikes has a pretty soft fork and unless i spin perfectly smooth when the cadence gets high the bike starts wanting to bounce. so i gotta crouch down, be real light on my hands and really concentrate on spinning a circle...or shift gears...ha...that happens quite a bit faster than 130rpm though.
