    front v-brake with rear disc?

    sad news, i found cracks in both chainstays. living in southern china, largest frame
    here is 17"...but i can order a 19". my former mtb is a 23" diamondback. i've located
    apparently the only other 23" frame in china (yes, they are made here, but only for
    export), an alu frame with no brake studs. disc only, chainstay mounts.

    i can transfer some of the components, along with the v-brakes on the heavy, steel
    fork (21cm headtube). the fork has a disc mount, but.......

    i'm not doing much heavy touring, usually around 10 kg on the rear rack. lots
    of rough roads, cobbles, landslides, jungle. v-brakes have sufficient stopping power
    for that load and my 85kg. we have long slopes here..... sometimes a 32km rise,
    followed by a constant 32-km descent.

    a disc would be nice during monsoon season. i'd be afraid of a disc in front as i
    imagine it'd be too easy to lock up the front wheel, especially in the wet. on the
    rear, less chance of overheating the rim on those long descents. and maybe less
    mud scraping off the v-brakes and dropping into the chain.

    v-brakes on the front would eliminate the disc dishing problem, and would give
    me a system i can get spares for in almost any tiny village hardware store.

    what would be the advantages/disadvantages to a mixed system....with the v-brake
    in the front and disc in the rear? anyone tried this setup?

    A disc front and V rear is a better setup as your primary brake is up front and with a good disc the modulation is excellent... with the right technique one should be able to apply full force to the front brake and not go over the bars and with a loaded touring bike the odds of this are decreased to a higher weight in the rear.

    the only frame available has disc mounts only. my current fork has both options.
    i'm not worried about going over the bars, i'm more worried about the front wheel slipping
    out, going off the edge (no guardrails in china!) and dropping a thousand feet onto the
    rocks (and gone-over-the-edge tour buses) below.

    i'm thinking of the rear disc like a tandem drag brake.

    i suppose i could just go with dual disk. easier to buy a pair of brakes and a complete
    wheelset. just wondering about the options.

    You mean all the other stuff is on the export docks?

    Put discs front and back--there's absolutely no reason not to.

    I'm assuming if you're touring, you're familiar enough with a bike that you know how much force it will take to put you over the handlebars.

    Disc brakes have just as much modulation as any other type of brakes, if not more (a lot of people argue that hydraulic brakes have more modulation than cable actuated discs). If you apply the brakes, they're not going to instantly lock your front wheel and send you flying, I promise.

    Not a thing wrong with your idea, and a lot right about it. The heavier braking power should be on the rear. Use it most of the time and preserve your front wheel rim. Best of both worlds.
