Description

When you're ready to move up, the DK Step Up 18 Inch is waiting. With a dialed 18 Inch top tube and a lightweight 6061 aluminum frame, this rig bridges the gap between beginner and badass. Chromoly where it counts, sealed bearings throughout the frame, and a parts list built for real riding — from 140mm 3-piece cranks to a legit 9T cassette hub out back. The Step Up is sized right, styled tight, and ready to rip. Perfect for riders graduating from a 16 inch but not quite ready for full-size 20.
