Had a slew of bike thefts and had to pick up an Access frame from Performance. I admittedly have been riding it with a seatpost that was out beyond the minimal insertion line. I've had it for 6 months now, fairly heavy usage. Its never been stiff like a superfly, but over the last couple weeks its been feeling really soft in the rear end. No crackage, but I was wondering if it was possible for the not-so-good aluminum they probably use to "craft" these things to soften up in that short of a time period. Its noticeable enough that I think I'm ready to spend some savings but was wondering if there were other culprits.
