its road conditions there is one stretch of freeway near me where it feels like im riding over speedbumps at 65. it eventually ends when a new stretch of pavement begins and all is well. but yeah at first i thought i lost the use of my shocks or springs.
I had a wobble at 83+. Had five 1/4 oz balance weights on front wheel. Took the weights off and took wheel in for balancing.Told them about the wobble.Service gave back the wheel and said it was balanced perfectly without any weights..(and suggested other possibilities, not knowing that I had removed the weights previously) took bike up to 85 and no more wobble....check your wheel balance....
did you put air in the tire?
if you have ran the tire with low pressure the tread will cup and give you a bounce feeling. putting air and balancing it will help after cupping but only fix is a new tire.
