The Dyan is our 24" wheel model. It is our best value with solid components at a starting price in the $500 range. The new upgraded version has an adjustable height stem, and 10 sp drivetrain. The Dyan has cold forged cranks, cassette with 9 or 10 sp drivetrain with 11-34 cassette, masterlink chain, disc hubs, integrated headset, rack, kickstand, fenders. We don't believe there is a 24" wheel folder with this level specs for anywhere near our price.
