    Smile Bike hubs

    Hi,

    I'm new to cycling and stuff, recently I saw that you can buy front and rear hubs for your bike's wheels like for instance "deore xt front hub":Bike hubs-new-temporary.jpg


    But how do you replace it with your old hubs? Do you need a bicycle mechanic?

    I would appreciate it if someone can help me out.

    Yeah, you would need to build a wheel around the hub, with spokes and a rim. You could either do this with your existing spokes and rim or with new ones. I think people generally only replace hubs when one is broken and even then they take the opportunity to upgrade more often than not.

    Some bike mechanics are wheel builders others aren't. You can do it yourself, but it requires a bit of skill. Regardless, you want a wheel builder rather that a general bike mechanic.

    Except you will most likely need different length spokes for a different hub.

    Someone who can't build a wheel shouldn't be called a mechanic. It's basic stuff.

    Other than a bit of skill you also need some not so cheap equipment like a truing stand, dishing tool, and ideally a spoke tension meter.

    Excellent points. The sad reality, though, is that a lot of "bike mechanics" can barely true wheels, much less build wheels.

    I am an expert in everything any bicycle or parts
    can have or do or assemble/disassemble. no problem

    but I stay the hell away from wheels and building them, I leave it to the
    wizards.

    I can also build a piano but no way can I tune one properly

    If you understand the basics, and you can true a wheel (which anyone can learn), you can also build one after watching a tutorial. It's really nothing special, but you need the proper tools.

    Generally it's cheaper to buy a new wheel than to rebuild one with new hubs if you can't do it yourself. Most bikes come with wheelsets that have relatively well matched components (i.e. low grade hubs generally come with cheaper spokes and rims) so if you replace the hubs you're only upgrading one of three parts that make a good wheelset.
    The most expensive bike in the world is still cheaper than the cheapest open heart surgery.

    Only on a Cannondale and only then if you're on an all meat diet.

    yeah I know. it is the lack of accurate truing stand and tensionometer stopping me

    trying to do it with the forks or stays as a truing stands is problematic

    I've trued several of my wheels with a rim-drive trainer.
    (It actually worked pretty well.)

    It's not hard.. hmm, ok it is hard at first. But once you get over the learning curve it's pretty easy actually. I taught my self by reading Sheldon's like 20 times lol. And truing stands are not that expensive, that is to say you can definitely build just fine on a cheaper 100 buck stand.
