    Centurion Ironman with Shimano 600 parts

    Centurion Ironman. I bought this because i loved how my expert ironman rode, so smooth but just wasn't my size.. I don't know what year it is but maybe you can tell from the bottom serial number. Fitted with Shimano 600 parts.

    1986 paint job and serial number, but the stem and handlebar are not original. The rest looks as built. Does it have the black face rear derailleur?

    That's the original '86 one

    But the seatpost and saddle are not original.

    Not that the non-original parts are any big deal.

    1986 frame, since no "Master" or "Expert" designation.
    That's the proper group, although the wheels could be either the copper-colored Araya A20 "rounded" or the Wolbers it appears to have, which were standard in 1987.

    Bars were Nitto B115 that year, swapped out for the Modolo Speedy.
    Stem was a standard Nitto, swapped out for that 3TTT.

    Brake levers early in '86 were Dia Compe drilled, with "leader" cables under the wrap. Hoods were Dia Compe, and red. Later in 1986, I think they switched to 600 levers as shown. Wrap was white, as far as I know, but a lot of that was up to shops.

    Seat post was a fluted SR, and saddle was a Turbo. Those have been changed.

    No big deal, I'd take it apart, clean and lube it, touch up the frame, repack everything with bearings, and ride it. Get a 7-sp freewheel for a pittance, drop on some 7 or 8-sp STI shifters and don't look back.

    Good job on getting a good bike.

    Thanks for the tips. Im pretty new to biking and have a few questions.

    I want to use this bike as a commuter to school (~2 miles) and was wondering if i would have to change the tires to a wider size.

    I also would like to get some sti shifters since they look like less of a hassle when shifting from the handle bar. But all my mikes are downtube shifters so i know little knowledge on the sti ones. Do i need both left and right shifter/brake levers to be sti or can i just leave one sti to control the rear gears. Don't have much of a budget to get the highend ones. Any recommendations for sti levers for cheap?

    About the 7 speed freewheel, would this one fit? Link

    And the bearings are in the crank and wheels right? Should i get new ones and apply grease or just use the old ones?

    Any help is much appreciated!

    New to biking and you have two Ironman bikes? Someone get me an aspirin! Oy! this kiddo.

    OK, STI upgrades are easy, but not with 6-sp. You'd need at least a 7-sp freewheel, which is cheap, about $10-$15, spin the old one off, spin the new one on, presto. The shifters are normally sold in pairs, but you could get by with a R one, others have done so, like Lance Armstrong.

    That freewheel? Nyet. The range is too wide for your rear derailleur.

    Others here may slay me for saying so, but to commute on that 1986 Ironman, you should change to a cheap 7-sp freewheel, flat bars, and go to eBay for a $25 set of Shimano MTB shifter/brake combos. They would work fine with the rear end, shift smoothly, and you'll have a commuto-rocket, a LOT cheaper than roading up to 7-sp STI. You'd better PM me if you try that, or we'll both get kicked out of the cult.
