I’ve been in that Basement a few times , killer stuff down there lotsa road stuff & vintage imports around 2007 & later
My pal Henri retired from that shop after about 7 years but put in maybe 25 years at Valencia Cyclery in the Mission District prior to American Cyclery I’ve been in that basement & back rooms too early 80s & up contemporary stuff there
But my pal Henri his basement at home was a hoard beyond the imagination he was a Schwinn man mostly prewar
Musta been close to 100 complete bikes in there , He had skills complete Bendix 2 sp teardown clean & rebuild in like under 15 minutes
He had a hoard on small parts for any hub
