Here is my story . I switched my stem like a month ago for a stem with a steeper angle. IT rode fine. Got a longer seatpost with setback and rode a week. I decided to try the old stem back to see if i needed it that high after i got my seatpost to see what was most comfortable and for some reason i feel a front/back shake in my handelbars when i go over bumps. When im on flat i dont feel it. I thought maybe i didnt but the stem all the way down so i loosend the bolts and pushed it down while i tighten them again. No go. Anyone have any ideas what it may be. Can it be my headset? ITs a WTB venom comp. Thanks for your help.
BTW IVe only had the bike since march so i dont think its ovalization on my head tube
