    i want to add a disc brake to the front of my cruiser. i have painted wheels so if i use a side pull brake it will rub the paint off. im looking for something i can add to a bike that never had it.

    eBay is your friend. Just search "disc brake set" under sports/cycling.

    I don't know how much you know about bikes so I am going to go into detail.

    You will need a fork that has a mount for a caliper. This I am 99% sure will only be a mountain bike fork. They do make them in a solid (non suspension) mountain bike fork if you want to keep the cruiser look.

    A bike fork has a part called a steerer tube. It is the tube that goes through the bike frame. The hardware that has the bearings and holds the steerer tube into the frame so it can rotate is called the headset.

    You will most likely have to change the headset because cruisers use what is called a threaded headset. This means the steerer tube on the fork is threaded. Mountain bikes use non threaded headsets. Some older mountain bikes use threaded like your cruisers but they won't have the tab on the fork for the caliper.

    Since you will have to change the headset you will need a new stem (the part that attaches to the handle bars.

    You will also need a new hub that has mounts for a disc for the disc brake. This means you will have to take your wheel apart and have your painted rim laced with new spokes to your new hub.

    As a recap you will need a new hub, spokes, rebuild wheel, new fork, headset, new stem at the least plus the brake and brake lever.

    Here is the break down in cost:

    brake - 45$
    lever - 20$
    headset - 30$
    fork- 50-100$
    stem- 25$
    spokes - 35$
    shop to build wheels -35$
    hub- 40$

    That is 280 -330$

    You could do it cheaper with used parts on ebay.

    Another thing I need to mention is they make different diameters of steerer tubes. The two most common is 1" and 1 1/8". Mountain bike forks are most commonly 1 1/8". I am not sure about cruisers. The bike shop can tell you what size it is. If it is 1" it will be hard to find a 1" with disc brake tab fork but probably not imposible.

    Hope this helps

    I just thought, There might be some guys on here that know of a company that makes and easy replacement fork for you. I don't know much about motorizing cruisers. There are a lot of people like the sponsors on the sides of this site that make specialty parts for us. Maybe there is someone making a kit for this?

    I make & sell the mounts.
    I'm currently out of stock on the Schwinn style mounts, but I have plenty of the Monark disc mounts.

    I forgot to mention the the link say the kits for chopper forks disregard that the kit works on any standard forks,it spins onto your hub,you must have threads on the left side of your hub.then you attach the billet disc brake adapter to your keystay,then attach your disc brake caliper to that,and bodda bing you got disc brakes,this was very easy to do.and like i said works very well,youll be able to stop on a dime.

    yeah you would need the billet bracket *Kicking*,and yeah its flipping sweet,I've done that disc brake set up on three of my bikes now,and I would never go back to standard brakes agin.The hole set up costs about $70 bucks thats the disc brake system and billit bracket,thats pretty cheap considering I've paid $80 bucks for my Avid Ultimate Pro V Brakes setup,and my disc brake setup stops way better then my avids.

    Anybody know if there is an adaptor to change the band brake on a heavy duty hub to a disc? If there isn't that any of you know of, I guess that will be my next project.

    I just changed my mechanical pull (cable) disc brake out for a hydraulic and man what a difference. Hydraulic is the way to go.

    I think the best setup for that nice bike would be a front drum/hub laced to your existing rim.

    It would be in keeping with the style as well.

    Some hub brakes include a generater as well.

    Shimano, Sturmey Archer and others make them.
