Was reading some of the stuff on how a flexible frame shouldn’t make a bike slower:
But I don’t think that’s a full view of the issues as they only used the bike a short time and didn’t adjust to it and deal with long term issues
Was thinking wouldn’t a less stiff frame in terms of side to side movement in the bottom bracket make for a different fit? In that when doing a fit wedges are sometimes needed to angle the foot to get the knee to track better. If a frame flexes then the pedal won’t be parallel to the ground but be at an angle in the same way a wedge would act. If someone gets fitted on a stiff bike (guru fit bike) and then rides a bike that flexes the effective angle of the foot could be different leading to a fit issue.
Am I missing something cause I never seen anyone take up this view?
