Man, I hate this situation... most of you probably know that I am returning my Dahon Mu P8, My wife has issues with her bike as well, including slipping seatpost, so we will probably have to return both bikes... Too bad, I really liked the bike but the slipping seatpost is unacceptable, I can't stop after every 10 minutes of light riding to raise the seat, it's ridiculous. It's a $600 bike and a solid seatpost isn't too much to ask.
My biggest concern is that I am not the only Dahon owner with this problem, this issue seems to be with the Speed, the Mu SL and the Curve. I have tried to clean the seat tube the shim and the seatpost, I have applied grease between the shim and the frame, I have tried 4 different seatposts, 5 shims and 2 QR clamps- I am so worn out from trying to fix this and generally speaking, I just had enough.
Basically, I really like the Mu SL, but what if I will have this problem with the seatpost, I really feel that maybe it's time to checkout a Brompton....although more expensive but maybe will be hassle free...
I have checked Bike Friday, I don't like the concept... I don't care if it takes 5 second or 30 second to fold the bike. I want it to be light, small and manageable, the Brompton looks like my only choice here.
Original budget was $600 but I guess I will have to invest some more in order to get something better.
Any suggestions ?
