    And the internet has given me nothing.

    I want to know how easy/difficult it would be to modify a single speed OCC Stingray to a 3 speed. I know how to do the cabling, I just need to know if a 3 speed hub would fit between the single speed rear stays.

    it's been done thousands of times ----- no major problems

    let's see my friend back in aprox 1964 had a Stingray

    which he had made into a 45 speed -- 3 sprokets front -- 5 sprokets rear with a three speed
    yes he had to spread his frame a long ways for all of that

    just locate and buy 20 in 3 speed wheel

    you probably will have to spread the frame a very little -- we did this often in the bike shop

    ride that THING

    always fun to add three speeds

    nice find there Bill
    that THINGS sweet

    It says original equipment
    I didn't realize that they came with a 20x4.25 -- that's pretty darn wide

    always fun to add three speeds to the motor bike

    all good MM
    the internal 3speeds have a rep of not holding up to engine power
    Roland (the sponsor) blew his up at deathrace (I tried to warn him :))

    ok. would an external 3 speed hub fit? adding the derailleur is easy, i just dont want to have to stretch the stays

    are 3 speed hubs heavy duty -- maybe not ??

    yes -- that makes good sense Bill

    we used to make repairs on 3 speeds
    a few of the parts inside -- did not look to be that heavy duty

    possibly made more for cruzing bicycle speeds of -- up to 20 mph at times ??

    where as many MB riders will be going at least that speed at many many times..

    stretching the stays -- commonly done -- when required to fit wider wheel

    we sure do like to ride those motor bike THINGS

    On theSheldonBrown Web site you can find info on how to go about doing this(steel frames).Three speed hubs need frequent lubrication (oil they have lube nipples).It's the lack of this that does them in.Mechanically they actually are quite sturdy..as long asyou don't shift under power.They usually have ratios of 0.75, 1.0 and 1.34

    well, even on my current bike i never shift under power. my idle is set perfectly so that the sprocket spins, just extremely slowly, because as i grew up i was told to always shift a bike while pedaling.

    i just need to know how simple it would be, and if i could do it with no torch n bend lol

    It seemed pretty simple but takes a piece of 2x4 to get enough leverage .GO to www.sheldonbrown.com & look under frames
