I have an old Centurion Sport DLX in my shed that I'm rebuilding. It has a Tange Champion frame with lots of alloy parts. It's a project bike that will take some time but I think is worth it. Was this a fairly good quality bike? Is anyone familiar with this particular model?
Centurion was a leading name in road bikes from around 1970 to around 1989, when the US importer decided to use the "Diamondback" name on all of their bikes.
Centurion imported bikes in the low, mid, and upper-mid price ranges. Their bikes were well thought of, as they combined some good design ideas, from riders such as Dave Scott, plus Tange steel tubes, and Japanese craftsmanship. At any given price point, they were among the better choices.
I decided to keep my Centurions exactly as they were in the 1980's, so when I replaced the brake levers, I used Shimano levers from the same era. Some folks have taken Centurion frames, and then updated them with a 2004 drivetrain, new wheels, STI shifting and new brake calipers. All of that stuff costs a bunch of money, more than some new 2004 bikes.
The drivetrain is a good clue to the original price level of a Centurion, with Shimano 600 components being used on the more expensive bikes from 1985 to around 1989. However, the Shimano 105 stuff from that era usually works as well as the 600, just a little less cosmetics.
As far as the components are concerned; the crank is "Sugino", the rear derailleur is "Suntour Seven", the freewheel is "Perfect", bars are "Sakae Custom". It had the old two position brake levers which I removed and replaced with Shimano Dia-Compe hooded levers. I have no idea what the vintage of this bike is, but I guess I could find out from the serial number stamped on the bottom bracket.
Thanks for your info.
