my bike starts making noises after riding for awhile and ive traced it to the seat post. if i unlock the seat qr and then relock it the noise goes away for awhile but then eventually comes back
im guessing the seat post is slipping in the tube but i dont know how to fix the problem. i thought maybe if i greased the post real good it would help but im not sure. any deas? what type of grease should i use?
