has anyone had any issues with the adjustable seatpost slipping? i am having problems now with regular seatpost slipping and I am going to try a different clamp. but I would like to get and adjustable post!!!
Out of 14 bikes, I've had only a few that haven't slipped. road or mountain. I've upgraded the seatpost clamp to hope at times and it stopped the slipping.
regarding your question, I have two joplins and neither slips.
Just bought a 2nd hand Maverick speedball Clamp is a Hope QR which i insisted was on the bike(Enduro SL) when i bought it.Nothing works better than the Hope,its been on 12 months with the original post and never slips.The Spesh stock ones are poor.
