    What are the various workarounds when using a smaller rear wheel than the frame is intended, so the brake pads/lever reach the rim ?

    Standard 27" steel frame, 26" rear wheel with chain sprocket mounted on 26" MB wheel.

    The pic. is the type of frame being used

    Much appreciated.

  2. Old school side pulls on BMX bikes will work but side pulls are weak compared to center pulls. Any reason why you want to use a 26"rim? Can't you use a 27"?

    i was just thinking (iknow i know bad idea lol) but obviously it would not be as strong, but at the mobile home sttore they have ths stip stuff with holes (like a metal version of those printer papers with the rip off sides) and since those have holes, if you mounded it right, what innd of strength would it have if i put it on my bike? (to make front brakes) the reason its sold at mobile home shops is cause they use it to hold screen doors shut when towing the trailers on the freeway. ill try to find a vacant house with it, they use it to keep vacant houses doors catching the wind constantly. just wondering.

    I am using the the 26" wheel from the bike I could not fit an engine to because it has limitations frame wise ( see the first link with the URL of the bike) and using a 27" frame I had stashed but no back wheel, only the front wheel.
    I think it will look cool with a large wheel in the front and a smaller wheel at the back and dragster type handle bars, ought to make look like a chopper effect when it's finished.

    it was sorta a reply, i was brainstormin, if u used a metal band around the back fork and mounded a center brake, that might work, i was asking about the durability.., cause i have a simmalar issue, my back brakes are just not powerful enough.

    The bike hanger was "featured" on my other thread. It's actually a spine stretcher. I used to hang upside down from the ankles, and the tilt would stretch the spine. Typical if one has the "mechanic's back" syndrome when the ciatic nerve gets pinched down the left leg.
    It worked initially,worked fine for a while till it gave me more problems than it resolved.
    So according to my doctor and physio, she siad not to use it anymore and it's best I use weights and swimming to re-align the spine when the nerve pinches.
    Swimming and floating I find works best, and a little bit of "this and that" works to, depending where it hurts !

    Anyway, when I started to build my first bike, the spine stretcher frame was able to support the bike frame and make it eye-level to work on or sitting on a chair while the bike is suspended.
    I was able to spin the back wheel and start the engine while on the frame and look at the wheel spinning. Great to see if all is working right.
    Yes, I must agree, it is a bit off-topic, but it works and most here I guess are mechanics, so I guess we can identify with back problems anyway.

    Whatever, the options are,
    to find a workaround to have rear breaks, or it might be simpler to get a 27" wheel sorted and ditch the idea of a 26" wheel on a 27" frame.
    Dare I say, it seems the latter, which means taking off the sprocket and rubbers on the 26" wheel and doing it all over again on a 27" wheel, but at least I'll have breaks !

    Suggestions welcomed.

    I still no comprendo ya idea so it's back to square 1, but if you happen to make it back, alive, can you please post a pic.


    Anyone else ?
     
  13. What about where your brakes mount? Do you have a welder? Maybe bring that mount closer to your wheel?
    Maybe there's a bolt on answer,but I'm lost as to what's trustable.

    I think the consensus comes down to a weld job, the same as the bike the brakes,cables and handles are coming off from.
    Has those thread things welded to the rear side down bars anyway.

    Hey boltsmissing -

    You need to measure the reach of the frame to the new 26" rear rim. You do this by mounting the rear rim with or without a tire, and then measure from the bolt hole where the brake attaches, then to the center of the rim where the brake pad touches. This number, in mm, tells you what brake reach you'll require. It will no doubt be 'long reach'. I'm guessing from the type of frame it is, that it does not have cantilever mounts for v-brakes/cantilievers. You can weld those on and those types of brakes are far better and more powerfull than any side pulls. IMO. You don't really need that strong of a rear brake as most of your braking is done by the front wheel. Have fun.

    Could you not use those horseshoe like things that seem to come on the front forks of new style mountan bikes? I think they may be used to stop the forks from twisting.
    My point is that you could mount it in the same way they do and you could drill a hole to mount the brakes . Just a thought.
    The pic is just to give you an idea of the part I am talking about but this is not removable and the ones I speak of just unbolt.

    Thanks cooltoy,turkeyssr

    Both are good options and make much better sense.
    I'll look around for a new set of horse-shoe breaks with long reach, if not, then weld a cross piece as turkeyssr has described, is the direction this minor issue is going.

    I was hoping perhaps some have made some sort of adaptor for the original horse-shoe without having to weld anything onto the frame and if this has worked OK before ?

    I've been going nut trying to find picks of that part but it's hard to find front shots of bikes. If your going to weld, then of course that is the best way and will be very easy. I just thought you could get this part and use two clamps or two u-bolts to hold it in place, drill a centre hole for the brakes and your done.
    As last time , this looks like what I'm talking about but this is just to give you and others a hint as to what in the world I am talking about. Thay used to just bolt on with one bolt on each fork.
    After looking at the pic again,this seems to be bolted in place and could be used.
