Just re-furbished my newly acquired Clockwork.I started with flats which were as I remembered them,but after the first shake down ride changed them for wider riser bars.Things progress and basically the original flats were too narrow for fine control,especially at slow speeds,and for the sake of my back I prefer to have the bars at the same level as the seat or even slightly higher.The seller of the Clockwork supplied it with the original flats and a pair of riser bars because he had gone through the same process.
BITD I bought both Clockwork and Prestige and each went through a period of change from new as components were swopped out and improved,including the bars.It was rare to find two Clockworks exactly the same as many people had them built up by the LBS and took the opportunity to incorporate their favourite parts at the same time.
This Clockwork is no different,so far it has acquired riser bars,a modern Orange branded saddle,a modern Orange branded water bottle and modern tyres.The bits that work,like the XT shifters have been retained,but as bought it had Biopace rings that I detest,and at the moment it has a Sugino chainset.The DX brake blocks had the consistency of concrete and have been replaced with a new set of Aztec brakes blocks,just as I used to do 20 years ago.
