Good frame, Orange always spent money on the frame and not the components. The base (stx) model C16 was priced up against bikes wearing LX kit. They also offered groupset options so often a Clockwork would be built as a XT and a P7 built as an STX bike depending on what the buyer watned for their money.
C16 commemorated the 16th revision to the Clockwork frame IIRC.
Somerset, like 'Heartbeat' with newer cars!
