I have a secondhand SMGT with a large, rigid seat. I've noticed a knocking sound that I put down to b the seat flexing and knocking against the frame when I go over bumps the knocking is only over bumps. Before every ride I lift the seat up as far as it will go and tighten the QRs. They still slip which is a concern, but only halfway down the slots.
First question is to any streetmachine owner with a hard seat, does yours ever contact the frame if the seat is right down?
Second, why could it be slipping? The QRs are very tight. I have washers between the seat slots and the frame bolt holes because iirc that's how it came.
Third, if I can't fix it properly, would it be good enough with ba thin strip of foam stuck to the seat with superglue where it contacts the frame? Bodge it.
Fourth, if replacement is needed (all other bodges I mean solutions aren't good) what seat is best? I assume the new GTe two part seat won't fit. So I also assume a mesh seat or a rigid seat made by iirc novosport are my options. The mesh seat being ventiseat I think? Any views?
I'm sure someone on here will have a good answer for me, you people always do.
