Let's see if I get this correctly: Mark Barnett was the most recent owner (before consolidating operations into Wheel Life in Belle Mead). He purchased the shop from Greg Turner, who owned it for a good number of years, having bought the shop from Somerville cycling icon Fred "Pop" Kugler. I know this 'cuz I was (for years) trying to buy his shop bike (a late 50s red Schwinn Typhoon)... he refused to sell it, because it belonged to Pop...
More recently Greg T was trying to open X-Arena, an indoor motorcross track in Trenton... Not sure the project is still alive. Greg's a good guy, despite refusing to sell me the Typhoon....
Peace,
