I have a new (about 3mo) old Front suspension hardtail aluminum frame - I wont mention brands at this time.
I like the bike. I've been using it a lot. However, I have one really annoying/painful problem.
I can't get the $*($%$ seat post to stay where I put it, it slowly sinks into the bike, unless I literally use 2 hands to close the QR.
Having the QR this tight obviously makes moving the seat up or down when I want too, less then a quick process.
I have tried putting a small shim into the seat post tube - this has not helped.
The seat post tube does not have 'ears', rather the seat post is held in place by a clamp which slips over the top of the tube.
On my older bikes, which have 'ears' on the seat post tube, this has never been a problem.
Does anyone have any suggestions on how to remedy this situation??
