[TheThinkTank] any coops in holland or rome?

hi all,

i'll be in holland and rome for a few weeks and want to visit as many
bike coops as i can to learn about how things are done there and
hopefully take some knowledge home to neighborhood bike works in
philly. does anyone know how to get in touch with any cooperative/ collective/community bike shops/programs in holland (amsterdam,
rotterdam, the hague...) or rome, italy? thanks,
