The Lineage Ground Master was created to take a DNA strand or two from our past and thread it into state of the art contemporary designs of the present. Look at this masterpiece, from a glance its difficult to tell from the original 30 years prior. But when you look closely, you will see all modern technology. Hourglass Mid BB, internal headset. Forks are full heat treated and butted same as the Kneesaver bars and 48 spline 19mm cranks. This bike is as high level BMX you are going to buy in todays market.
