This is a 1990 D'Back Sorrento I bought for about $50 from a guy in Laguna Niguel. Original owner, maybe 10 miles on it. It is a lower end bike, and had a 200GS(Biopace) drivetrain. I put a full DX(Biopace) drivetrain on, and custom built wheels with Avenir branded Sun made rims. The seat, pedals, grips, cage, and bottle are all Avenir (D'Back(Raleigh) accessory brand at the time). The tires are gumwall repop Comp III's as a nod to D'Back's BMX history. Very sweet, somewhat period specific bike.
