About This Product

The Haro Lineage Ground Master 19.5”TT BMX Freestyle Bike-Chrome looks straight out of 1991, but oh boy is it ever a modern bike. Comparing it to the original you’ll see right away that the chain stay and seat tube are both a bit shorter. The gearing is a modern 25/9. After 30 years the rear Dia-Compe u-brake has migrated from the top of the chain stay to the bottom of the seat stay. The bottom bracket has morphed into an hourglass mid. And the fork now has tapered fluted legs. If you are looking for a next-level freestyle bike with a proven heritage then THIS is the bike to get.
