    6 speed to 9 speed conversion, I need a parts list

    1st post so bear with me. I have been an avid MTB for 15 years. I recently decided to get into road biking for exercise. I bought a beautiful Trek 500 tri-series.
    I know it would be easier and probably cheaper to just buy a new bike, but I really love the way this steel bike rides and feels.

    I want to convert it from a 6 speed friction to a 9 speed indexed with brifters.
    Can you guys give me a parts list of what I'll need in order to do this. I will be buying parts slowly over the next several months.

    I know I need a new wheelset, 9 spd. cassette, 9 spd. chain, rear deraileur, front deraileur, brifters.

    What else am I missing??

    Thanks,
    Tony

    Rear spacing? Before you start gathering parts, check the rear spacing.. 6 speed likely means the frame is spaced at 126mm(or possibly even 120mm). You need 130mm rear spacing to run 9 speed. If the frame is steel, it's possible to spread the rear from 126 to 130. If it is aluminum, probably not..

    I believe the Trek 500 Tri was only built in 1986, and was Reynolds 531. You will be able to spread the rear from126 to 130 with no problem.

    Though you can use your original crank, I would really suggest getting a modern one that matches the drivetrain. You would only need a rear wheel, the front is fine. One of the biggest improvements I've found on modern bikes is the brake calipers. They are MUCH better than the Shimano Z series than came on your bike.

    your list so far

    new rear wheel or a new hub to be laced into your existing rim
    rear derailleur
    front derailleur
    brifters
    crankset
    chain
    cassette
    cables w/ housing
    cable stops for downtube braze ons

    the first half of that list can be purchased used, the second half you probably want to buy new

    If the OP buys new brifters, they come with cable stops.

    No sh!+? So Shimano expects you to buy their $40 cable stops to use with their $140 (2300) brifters?

    Guess I'm glad I have an inventory of 100 or so of them here.

    EDIT: You're right. Just checked the new set of 105 brifters here....no cable stops.

    How are those 2300 brifters? I have a buddy that might be doing something similar to this soon (7 to 9/10 conversion)

    You'll see people rag on them on here a lot. I think they're fine. I'm a Campy guy, so I'm used to the thumb levers. Considering their price, they're fine for old bike conversions. I have a pair on my 1970s Stella.

    How about a pic of your new ride before the parts are swapped?

    At your option, you don't need a crankset. If Shimano, update the big chain ring for one with the shift pins and you are good. I'm using a 600EX with a 6500 A series big ring. This was also used with the 7700 DT and now 7800 shifters. With all those new parts, might as well buy the crankset and that will also need a bottom bracket. If that far, might as well consider some updated brakes.

    Are you sure you don't want to just buy a complete bike?
