A beautiful 1999 George Longstaff tandem trike.
Current trim:
Campagnolo ATB/tandem chainset
Campag front and rear mechs, Centaur 9 speed rear and a Racing T on the front. Only a 7 speed double freewheel though. Campag ergo shifters on the front (possibly Record).
Shimano RX100 levers for the stoker controlling Hope disc brakes on the rear wheels. The front brakes are Dia Compe Vc 737, mounted fore and aft of the fork crown.
Hope front hub and unmarked, possibly Longstaff own, rear hubs. Cinelli bars and stem, cheap pedals and saddles which will be replaced very soon.
