If you go to the Split Pivot site it doesn't look updated since 2007. It doesn't specifically mention any companies planning on using it. It does state "patent pending". So did DW and Trek come to an agreement whereby ABP marches on and Split Pivot went away or is DW waiting on the patent to be awarded so he can start licensing the design and charging Trek? I did notice that the position of the chainstays and seatstays at the pivot are reversed between ABP & Split Pivot.
