Thanks in advance for any help you can give on what this is worth and if it is worth more if sold as parts...
I’ve got a 1987 Centurion Ironman Expert "Miami Vice" that I’ve had since high school (~1996). Previous owner upgraded many of the parts and I’m wondering if the parts are more valuable than the bike as a whole. Some of the parts I can find comparibles on eBay. But finding the value of some things, especially the cranks is a little tricky. Always kept indoors, but ridden without being pampered over the years.

Frame: 58cm (c-t) some rust and wear here and there
Front derailluer: 105 (stock)
Rear derailluer: Dura-Ace 7 speed (12-26 cassette)
Shifters: Dura-Ace downtube shifters (rear is indexed)
Cranks: “Cook’s 176mm” with 52-42 Shimano chainrings
Wheels: Campagnolo “Omega 19” laced to Dura-Ace hubs front and rear
Seat post: Campagnolo “Brev. Inter”
Seat: Vetta Suede (stock)
Brakes/levers: 105 (stock) rear lever missing small plastic piece under hood. Hoods are misfitted because these were "emergency replacements" about a decade ago.
Headset: 105 (stock) with crack in plastic seal (always covered in Lizard skin since I bought it)
Bar/Stem: Nitto (stock)

Let me know what other information you need. I can upload more pictures (i.e. Serial number, etc) if that makes a difference.

Parts. There's really nothing much original about it anymore. Sell the frame complete with forks, headset and bottom bracket.

Thanks for the advice. I’m having trouble finding the equivalent cranks on any auction sites. Any suggestions for how to find them? Scouring these forums I saw one similar pair in the “Favorite Cranksets gallery” which called them Cook Bros Track cranks, but even using that as a search term I can’t find any for sale or in completed listings that match. Any other search suggestions?

I got a picture of the serial number this evening after work.

Nice!

YEs - in this case, worth more as a part out --

but as a keeper, i'd replace the remaining 105 parts with Dura Ace , swap the post out for either a Dura Ace if you can find one, or a black Control Tech or something similar to extend the theme from the black crankset and ride off into the sunset --- The crankset is a period correct upgrade and looks cool on the bike.

WRK101 nailed it as usual. He has tons of experience with eBay so I take his comments seriously. The frame is sadly in need of TLC, but it is an awesome frameset. I owned one and sold it due to lack of space but would have kept it if I could. The ride was uber-smooth.

Part it out. You won't get a real lot for the frameset. I paid $100 a few years ago for the frame, fork and headset which was in perfect condition.

Re: bottom bracket. I see people leaving it with the frame but my thinking is it’s better with the cranks (assuming the chainline is good). A 68mm English shell takes any English BB but those Cooks cranks are going to want the spindle length of that BB. Saves the buyer a lot of trial and error when installing in the next 68mm shell frame.

If those Cooks cranks are the same as Cook Bros, they likely have quite a high value in the vintage BMX market.

In this expired sales ad I found a little info about Cook's.

CQP Cook's Dogbone Crankset: 176mm - Milled - 110/74mm - 46/36/24t - Bike Recyclery

This 1st gen Cook's Quality Products crankset was the original "Dogbone" crank. These came out of Gary Cook's workshop, whereas the Cook Brothers CBR/RSR Dogbone crank was based on Gary's design but produced by Jack Whitmer under Cook Brothers Racing (which Jack bought from Gary Cook in 1982).

Thank you! This is awesome. I thought they must be older than the CQP cranks I’ve seen around that are labeled C.Q.P., and I found a couple scans of announcements from ‘88 or ‘89 that looked similar, but this is spot on.

Namnad510,
Is that picture just a bit altered, or do I see a potential separation of the down tube starting to form? If so the frame is trash! JMHO, MH
