I ride a 2003 Raleigh USA Competition, all triple butted aluminum with carbon forks and a 9-speed Ultegra drivetrain. The only thing that I have changed was the wheelset. I am a little too large for 16 spoke wheels. It is a good comfortable ride.
I also ride a 1978 vintage English Raleigh with a mixed drivetrain consisting of late 70's vintage Dura Ace front derailer, Dura Ace clamp on shift levers, Front and rear Dura Ace hubs, a Shimano Crane rear derailer, Shimano 600EX non-aero brakes, and a Shimano 600 6-speed Freewheel 13T-18T. I did change out the no-name bottom bracket with a sealed hub and changed the old Sugino crankset with a Shimano 105 crank. This bike has the derailer cables routed over top of the bottom bracket which was common back then. I couldn't find a Shimano cable guide that would work with the front derailer so I had to go with a Campagnolo cable guide. It was expensive but it sure is purty. Of course the frame is a steel frame but it still is a pretty sweet ride. The main reason that I even keep it though is that it was my first serious bicycle bought new in 1978.
I have a mix of other bikes that I ride on occasion but the 2003 Raleigh is my main horse right now.
