Ok so i've heard that the seatpost on the GF cobia (bontrager sport) sucks and that it slips and what-not. I also was hoping that it was just some crazy malfunction thats not gonna happen to me but that turned out to be wrong...so anyways im looking for a new seatpost and want something around $40 my LBS has three im looking at and was wondering if they were worth it...
1:Cannondale Fire Carbon 27.2x250mm ($40)
