1989 Centurion Dave Scott Ironman Expert

I just picked up this bike for $160 and wondered if someone could tell me how I did. I am pretty sure it is a 1989 because of the Suntour GPX components and the 2nd number in the serial is 9. This bike looks to be mint condition. I plan on riding it not reselling. One quick question I have is what is best to clean it up without risking damage to the paint. Also is there any urgent maintenance that I should be done before I ride. I also got two tires in the deal. Thanks.

You did fine. Replace bearings and grease and lube the chain. Every vintage bike I find is in desperate need of this service. You risk doing damage to bearing surfaces, particularly wheel hubs, if you neglect this. If you are not ready/able to do this work, have a shop do it for you.

Later I would replace the cables and maybe brake pads. Actually, just looked at your pics, brake pads look good, as does the one cable I can see.

Sorry I'm late to the party, but I've filled in the OP already.

'89 Expert models came with Suntour GPX group, incl wheelset. Tange Levin CD headset, Tange BB. 52/42 crankset, Araya CTL-370 rims and very hard Panaracer Technova II tires in 700x20 that were almost universally despised for being rock-hard.

Colors were black and smoked blue fade. There may be others, but there's no catalog around to confirm anything in that regard.

Geometry, per Centurion, was tweaked for '89, but magazine tests were all of non-black models and they couldn't confirm a change. 3 owners of the black ones, who also have other Ironman models, think the black model feels a bit faster/quicker. I am one of those convinced that, if there was a geometry change, it made it to my black one. Probably simple a psychological effect.

Prices that I tracked for 2 years showed shipped price $240-$275 on eBay. Lately, I've seen some better prices on CL, notable drrobwave's near mint '88 Expert well under $200. The black ones generally bring good $$ if they're clean. I've built two, and one went, heavily upgraded, for $600+. BF members thirdgenbird and lsdmt each have one, with thirdgenbird's flying with Campy, lsdmt's running 600 tricolor.

I'd pay $160 all day, every day. Great frame to upgrade to modern stuff and never need another. Hard to lose money at $160. Parted out, would bring even more. I've paid that much, with shipping, for a pristine black Expert frame. Most of them run $80-$150 for the framesets.

Good luck. Glad you bought it.

The strong point of the bike is it's fine frame, Tange 1, and the excellent components offered for the price, both then and now. Suntour GPX, in my experience, sits between 105 and 600, with better calipers then the 105 and not as smooth in the shifting as 600. Easily upgradeable, the FD and RD will handle upgrades to at least 9-sp STI that I've seen and done.
